Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.13:test (default-cli) on project testtest: No tests were executed!  (Set -DfailIfNoTests=false to ignore this error.) -> [Help 1]

It took me some time to find out why, because there are some potential sources for this effect. First I started to check if I happened to have a hidden JUnit 3.x dependency, because that would effectively turn JUnit4.x off. Nothing.
Then I found out that the effect appeared to happen only when certain dependencies where set.
I noticed that the problem appeared when AnnotationProcessors where in the list of direct or indirect dependencies of an affected project.

Dealing with AnnotationProcessors in maven has its issues, so I already had downgraded from maven-compiler-plugin 3.0 to 2.5.1 for the projects that contained AnnotationProcessors (See http://stackoverflow.com/questions/4941355/maven-annotation-processing-with-maven-compiler-plugin) and configured the compiler-plugin to compile with -proc:none. At first I thought “-proc:none” might cause the problem (see http://jira.codehaus.org/browse/MCOMPILER-97 for details / workarounds / ideas on that one). But none of it was the case (I even switched back to maven-compiler-plugin 3.0 for now and everything works fine).

It came as a surprise to me that the actual problem had a totally different source:

The real problem and solution

After Renaming an AnnotationProcessor, I simply forgot to change the content of “META-INF/services/javax.annotation.processing.Processor”, which must contain the fully qualified ClassName of the AnnotationProcessor! Notice that a projectbuild usually doesn’t fail when this entry doesn’t match an existing className. However, it’s a weird effect that UnitTests will fail for all projects that define a Dependency to such a project either directly or indirectly.

<dependency>
    <groupId>org.netbeans.cluster</groupId>
    <artifactId>ide</artifactId>
    <version>${netbeans.version}</version>
    <type>pom</type>
</dependency>

However this doesn’t work too well in my current multimodule / module-suite setup.
Collecting the dependencies for the Xml Editor with Xam has always been a long-lasting pain during development. When I changed the structure of the application it often broke and I had to go through the dependencies in a trial/error manner which took a lot of time.
To make things “easier”, this time I created a “Reference” Netbeans Application Project (not using maven) and went to the Properties-Libraries Panel. I started with checking “Extensible Abstract Model (XAM)”. The Libraries Panel then shows you warnings telling you which Libraries would be needed as well. So I clicked my way through the dependencies and wrote everything down manually (you need to look at the tooltip for the actual name of the module and you can’t copy that tooltip, so copy/paste was not an option. Rather my options were pen and paper *sigh*).

Note that currently NbTestCases / Jelly Tests are not working anymore once you include certain modules (tax and freemarker in my case).

So this is the complete list, I collected this way (there are additional dependencies at the bottom, I documented their purpose inline in the following xml:

C:\ProgramData\Desura\DesuraApp\GDF\

on a Windows-System.

The dlls have numeric filename-prefixes, but it’s always the same numbers (so I guess each dll maps to an installed game).
For some days now, everytime I started the Desura-Client, Avira warned about a Trojan:

TR/Kazy.65525.12 in C:\ProgramData\Desura\DesuraApp\GDF\54528904790048.dll and in C:\ProgramData\Desura\DesuraApp\GDF\RCX3C2D.tmp

It was always the same dll-filename.

According to the Desura-Support, this is a false positive. (Thus it’s actually not a Trojan according to the Desura-Support)

However: I was wondering what these dlls are for. Apparently these dlls are used to display the games in the start-menu -> games folder.
Checking the option “disable windows games explorer” in the client settings solved the issue, so that dlls are not being created on startup anymore.

Dependency problems

When you want to install certain modules in your standalone application based on Netbeans RCP-Application, make sure to use <type>jar</type> in order to have it considered transitive. This way, Netbeans will install dependent modules as well. Otherwise, (e.g. when using <type>nbm</type>) you’ll end up adding tons of modules required by other modules directly, which is time-consuming (run-time trial-error), annoying and less maintainable.

When you get errors on startup, saying “Could not install xyz”, make sure to check the file target/userdir/var/log/messages.log of your application in order to get more useful error-messages.

Solution:

It is actually a bug in CompletionUtil.isDTDBasedDocument, because it doesn’t check for the reasonable return value null. But the source of the problem is that there’s no appropriate LanguageProvider registered.
Add the Dependency org.netbeans.modules : org-netbans-modules-lexer-nbbridge, which provides org.netbeans.modules.lexer.nbbridge.MimeLookupLanguageProvider.

	<type>jar</type>
</dependency>

important: since Release71 (not beta anymore) I experienced the error-message “Module dependency has friend dependency on org.netbeans.modules.editor.settings.storagebut is not listed as friend” when using the above dependency declaration. Solution: add scope runtime.

<dependency>
	<groupId>org.netbeans.modules</groupId>
	<artifactId>org-netbeans-modules-editor-settings-storage</artifactId>
	<version>RELEASE71</version>
        <scope>runtime</scope>

java.lang.ClassCastException: org.openide.text.FilterDocument cannot be cast to javax.swing.text.AbstractDocument

This bug might appear when you’re dealing with the XML-Schema-Module. In my case, it appeared when I was trying to get a Xam-based-approach working with MultiViewEditor. I copied sourcecode from the Schema-Module in the first place in order to get a glance on how that works.

Hint for Solution

Thanks to Jesse Glick from the nbdev mailinglist: Make sure the editor-related modules are enabled in your app. The resulting BaseDocument should be assignable to AbstractDocument.

Module dependency has friend dependency on org.netbeans.bootstrapbut is not listed as friend.

Description

When dealing with org.netbeans.modules.xml.xam.ModelSource. (But appears in other constellations as well, so transfer the solution to your constellation. Debugging by temporarily adding the implementation-dependencies helps a lot.)
I had this problem in a submodule that used ModelSource. As soon as ModelSource was used somewhere, this error-message appeared when compiling.
In order to resolve the issue, I added implementation-dependencies in the first place. It was not sufficient to only add org-netbeans-bootstrap, but core-startup and netbeans-core would be neccessary too.
Note: This is not the solution but the way I went:
I modified src/main/nbm/module.xml and added these to the <dependencies> section:

<dependency>
	<id>org.netbeans.modules:org-netbeans-bootstrap</id>
	<type>impl</type>
	<explicitValue>org.netbeans.bootstrap/1 = 201109252201</explicitValue>
</dependency>
<dependency>
	<id>org.netbeans.modules:org-netbeans-core-startup</id>
	<type>impl</type>
	<explicitValue>org.netbeans.core.startup/1 = 201109252201</explicitValue>
</dependency>
<dependency>
	<id>org.netbeans.modules:org-netbeans-core</id>
	<type>impl</type>
	<explicitValue>org.netbeans.core/2 = 201109252201</explicitValue>
</dependency>

Then the actual error-message occured when compiled:
“Project uses classes from transitive module org.netbeans.api:org-netbeans-modules-xml-xam:jar:RELEASE71-BETA which will not be accessible at runtime.”
Which basically means that you have to add this module as a direct dependency:

Solution

Add this to the dependencies-section of your pom.xml:

<dependency>
	<artifactId>org-netbeans-modules-xml-xam</artifactId>
	<groupId>org.netbeans.api</groupId>
	<type>jar</type>
	<version>RELEASE71-BETA</version>
</dependency>

Afterwards, you should remove the previously added implementation-dependencies from src/main/nbm/module.xml if you followed my debugging steps.

JellyTools not working and problems with JUnit

I noticed that in my multimodule maven application JellyTestCases just wouldn’t be executed. After some research, I noticed the following hint:

Using configured provider org.apache.maven.surefire.junitcore.JUnitCoreProvider

This message just didn’t appear in a reference Application (where JellyTestCase works) that I just created from the scratch in order to find the problem.

So I compared the effective poms. In the “broken” app (the one where JellyTestCase wouldn’t work), I found the maven-surefire-plugin to have a dependency-section that wasn’t there in the working pom:

<!-- not working -->
<groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-surefire-plugin</artifactId>
                    <version>2.13</version>
                    <dependencies>
                        <dependency>
                            <groupId>org.apache.maven.surefire</groupId>
                            <artifactId>surefire-junit47</artifactId>
                            <version>2.13</version>
                        </dependency>
                    </dependencies>

So I deleted this section:

<plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-surefire-plugin</artifactId>
                    <version>2.13</version>
                    <!--dependencies>
                        <dependency>
                            <groupId>org.apache.maven.surefire</groupId>
                            <artifactId>surefire-junit47</artifactId>
                            <version>2.13</version>
                        </dependency>
                    </dependencies-->
                    <configuration>
                        <systemProperties>
                            <property>
                                <name>cluster.path.final</name>
                                <value>${project.build.directory}/${brandingToken}/${brandingToken}:${project.build.directory}/${brandingToken}/platform</value>
                            </property>
                        </systemProperties>
                    </configuration>
                </plugin>

Which then almost worked. There was the following Build-Error:

org.netbeans.junit.NbModuleSuite$S@326906a1(org.netbeans.junit.NbModuleSuite$S)  Time elapsed: 0.354 sec  <<< ERROR!
java.io.IOException: no match for junit:junit:4.10 found in [tons of paths]

	at org.netbeans.junit.NbModuleSuite$S.runInRuntimeContainer(NbModuleSuite.java:855)
	at org.netbeans.junit.NbModuleSuite$S.access$100(NbModuleSuite.java:660)

I could solve this problem by defining my junit to be version 4.10 instead of 4.11:

            <dependency>
                <groupId>junit</groupId>
                <artifactId>junit</artifactId>
                <version>4.10</version>
                <scope>test</scope>
            </dependency>

NbModuleSuite: java.io.IOException: no match for [...] found in

When having ApplicationTests, such as NbTestCase or JellyTestCase, sometimes there are errors like the above. In my case it has been the following error (beansbinding):

org.netbeans.junit.NbModuleSuite$S@2eb9eee9(org.netbeans.junit.NbModuleSuite$S)  Time elapsed: 4.122 sec  <<< ERROR!
java.io.IOException: no match for org.netbeans.external:beansbinding-1.2.1:RELEASE72 found in [...lots of paths...]

	at org.netbeans.junit.NbModuleSuite$S.runInRuntimeContainer(NbModuleSuite.java:855)
	at org.netbeans.junit.NbModuleSuite$S.access$100(NbModuleSuite.java:660)

I found this bug-report among others:
Netbeans.org Bugzilla #225522 which might describe the problem. chrislovsund states there:
"I found that the method org.netbeans.junit.NbModuleSuite$S.rewrite doesn't
consider an maven dependency with <classifier> set. I have fixed with a simple
patch for now."
As I'm not willing to use nb-patches in my application, I'm left with Jesse's statement, which basically says that this problem persists in RELEASE-72 and even RELEASE-73-BETA2.

Fortunately in my case, I was able to decouple the parts of the code that needed beansbinding (was just a feature on top that isn't needed for the application itself) and could easily be decoupled. The only other "solution" would have been to have no FunctionalTests whenever this problem arises (just delete the Tests). *sigh*

Here’s the solution:

The easiest way to start is to open your layer.xml-file in the explorer view (by using the plus-sign, don’t open it in the editor). Search the folder <this layer in context> and search for the Windows2-folder. Open it. You should see a favorites.wstcref entry. Double click.
change <state opened=”false” /> to <state opened=”true” />.
Make sure to specify a module tag (see below on how to get this right)..
Netbeans created an entry in the layer-file for you that should look like this:

            <folder name="explorer">
                <file name="favorites.wstcref" url="favoritesWstcref.xml"/>
            </folder>

If it didn’t, create that entry on your own now.
Here’s some context-info, just place that section anywhere directly under the filesystem-tag:

    <folder name="Windows2">
        <folder name="Modes">
            <folder name="explorer">
                <file name="favorites.wstcref" url="favoritesWstcref.xml"/>
            </folder>
        </folder>
    </folder>

Netbeans also created a file named “favoritesWstcref.xml” for you under src/main/resources/path.to.your.package. The name doesn’t matter, just make sure to have the same name as referenced by the url-attribute of the file-tag in the layer.xml (see above).
The file should look like this (although Netbeans might not have created the very important module-tag. Just make sure to have everything just like below in the favoritesWstcref.xml-file):

<?xml version="1.0" encoding="UTF-8"?>
 
<!DOCTYPE tc-ref PUBLIC
          "-//NetBeans//DTD Top Component in Mode Properties 2.0//EN"
          "http://www.netbeans.org/dtds/tc-ref2_0.dtd">
 
<tc-ref version="2.2">
    <module name="org.netbeans.modules.favorites/1" spec="1.25.1"/>
    <tc-id id="favorites" />
    <state opened="true" />
</tc-ref>

You’ll wonder which settings to take (especially when you don’t use Netbeans RCP Release701 as I did here).

You can look that up in the dependency which you will define right now.
You need to define a Dependency to the Favorites module in order to make sure that it gets loaded before your module, otherwise you’ll have a Favorites-Window that disappears under certain circumstances on startup or won’t show up at all.

To define the dependency you might want to search by right-clicking the “Dependencies”-Folder and choose “Add Dependency…” enter “favorites” in the Query-Input-Field and choose the appropriate module and version (in my case “org.netbeans.modules : org-netbeans-modules-favorites” RELEASE701 [nbm] – netbeans)
Or you could simply add it to your pom.xml under dependencies like this:

        <dependency>
            <groupId>org.netbeans.modules</groupId>
            <artifactId>org-netbeans-modules-favorites</artifactId>
            <version>RELEASE701</version>
        </dependency>

Once downloaded have a look at Dependencies/org-netbeans-modules-favorites-RELEASE701.jar or whatever version you chose in the explorer-window of netbeans. Open META-INF/MANIFEST.MF to get the infos you need for the above mentioned module-tag in the favoritesWstcref.xml-file.
The important entries are:

OPENIDE-Module: org.netbeans.modules.favorites/1

and

OpenIDE-Module-Specification-Version: 1.25.1

These two values are needed for the attributes of the modules-tag in the favoritesWstcref.xml-file.

When you build your project, you will get an error-message saying:
“Failed to execute goal org.codehaus.mojo:nbm-maven-plugin:3.5:manifest (default-manifest) on project [...]: Module dependency has friend dependency on org.netbeans.modules.favoritesbut is not listed as friend. -> [Help 1]”

This means that you have to specify an implementation version of the favorites-module (which is pretty bad, because your module will only work with this very version afterwards). You can specify that you wish to use the implemenation version by modifying src/main/nbm/module.xml to contain the following entry:

    <dependencies>
       <dependency>
            <id>org.netbeans.modules:org-netbeans-modules-favorites</id>
            <type>impl</type>
            <explicitValue>org.netbeans.modules.favorites/1 = 201107282000</explicitValue>
        </dependency>
    </dependencies>

Again, have a look at the Dependencies/org-netbeans-modules-favorites-RELEASE701.jar /META-INF/MANIFEST.MF to find the right values for explicitValue:
the important values are:

OpenIDE-Module: org.netbeans.modules.favorites/1

and

OpenIDE-Module-Implementation-Version: 201107282000

If you get an error like the one below at runtime (open View/IDELog, when parts of your applications GUI or functionality are missing on startup, you’ll find the errors there (just be patient, they’ll appear in a minute)), then you’ve got a typo in your module.xml.

Anyway. I wanted to install FindBugs Plugin for Netbeans 7 and the long search for a correct update center to get this plugin was finally successful. There is a problem with urls like https://sqe.dev.java.net/updatecenters/sqe/updates.xml as the folks at java.net don’t seem to care about ssl-certificates and at least sqe.dev.java.net doesn’t provide a valid certificate.

This is why firefox and netbeans refuse to use the url. While I can tell Firefox to ignore that, Netbeans simply refuses the url. Ok.

Finally – after reading loads of threads and after a long time of trial and error, I found this one: http://deadlock.netbeans.org/hudson/job/sqe/lastStableBuild/artifact/build/full-sqe-updatecenter/updates.xml.

You should know, that while installing FindBugs / SQE, there are numerous Plugins to be installed which are not signed. Netbeans will warn you about that.

//make sure to add your classpath, e.g. cp.appendClassPath(new LoaderClassPath(loader));
 
//throws no Exception
CtClass cc = cp.get(className);
 
//this would return a non-null object (alternative to above line of code)
//CtClass cc = cp.getOrNull(className);

But as soon as you invoke cc.getAnnotations or similar, it either fails silently (then add “catch (Exception e)” ) or (after you added the catch-block) you get a Runtime-Exception:

Make sure to call ClassPool::get with a ClassName not containing slashes, but dots. That is:

instr.addTransformer(new ClassFileTransformer() {
  public byte[] transform(ClassLoader loader, String className, 
                                    Class classBeingRedefined, 
                                    ProtectionDomain protectionDomain, 
                                    byte[] classfileBuffer) 
                                        throws IllegalClassFormatException {
                        //NOT THAT WAY:
                        //CtClass cc = cp.get(className);
                        //BUT THAT WAY:
                        className = className.replace("/",".");
                        CtClass cc = cp.get(className);
...

Otherwise, ClassPool would happily populate your CtClass but it would fail on

//line 191 of CtClassType.java in javassist:javassist 3.14.GA
if (!cf.getName().equals(qualifiedName))

and throw an ugly Runtime-Exception, when you try to inspect Annotations.
