I use Zen's Maven plugin to develop my JavaFX 2.2 application using Maven. The following is the plug-in declaration.
<plugin>
<groupId>com.zenjava</groupId>
<artifactId>javafx-maven-plugin</artifactId>
<version>2.0</version>
<configuration>
<mainClass>${mainClass}</mainClass>
</configuration>
</plugin>
I fixed the classpath using the following command:
mvn com.zenjava:javafx-maven-plugin:2.0:fix-classpath
and the fixing probably succeeded.
The compilation also worked but the process did not generate JavaFX main files such as the following:
/com/javafx/main/Main$1.class
/com/javafx/main/Main$2.class
/com/javafx/main/Main.class
/com/javafx/main/NoJavaFXFallback.class
Running the project produces the following exceptions:

What is going wrong and how can I fix it?
The main jar doesn't contain these classes, but the plugin generates an additional jar in the "target/jfx" directory (or something like this). Use that jar to start your application.

Using Maven I am creating a jar-with-dependencies for a project that uses ClasspathSuite to create a JUnit test suite. When running the jar from the command line I am running into an issue where the project classpath isn't being supplied like it would be in Eclipse.

I need the project classpath so that ClasspathSuite can scan my files to build a junit class suite. I have been searching a number of ways to allow maven to include the classpath in my pom such as <additionalClasspathElements> or <Class-Path> but I cannot get the value to appear in the system property java.class.path. At this point I am unsure if I am just walking down a rabbit hole that isn't going to work.
Is it possible to have a classpath in my jar's manifest that will point to one of the jar's directory? In this case ./com/....
How can I have this classpath referenced so that maven will include it when the jar is executed?
I write project work with osgi + aspectj. It work ok in Eclipse Kepler, but when I upgrade to eclipse 4.4 (Luna) then get error:
I open org.eclipse.osgi*.jar found in Eclipse Kepler and see class org.eclipse.osgi.baseadaptor.HookConfigurator
But in Luna not found.

I have followed the instructions here, it's based on Eclipse Kepler, but I use Eclipse Luna.
Please help me.
Equinox Luna has change many of the internal details that require all equinox framework hook implementations to be migrated to use the new hooks. It is unclear to me what you have installed that is trying to implement HookConfigurator from the stacktrace. If it is the Equinox weaving support which supports weaving with aspectj then you will need the Equinox weaving bundles released with the Equinox 4.4 (luna) release as well.
If not then what ever framework extension you have installed that does weaving will need to be migrated to the new Equinox framework specific hooks in luna.
I have a uber jar that's already generated (not via Maven; I just have the jar). I need to use it along with another jar, which has dependency conflicts. I'd like to shade all the libs in the first uber jar, except for a few classes which need to be public.
What is the setup to take an existing jar, and use Maven shade plugin to rename most (except for a whitelist) of its classes, generating a new uber jar?
You can do a "rename-all" type of activity with maven-shade-plugin. For example:
<relocations>
<relocation>
<pattern></pattern>
<shadedPattern>relocated.</shadedPattern>
<excludes>
<exclude>com.myfirm.level1.level2.*</exclude>
</excludes>
</relocation>
</relocations>
Will essentially move every package a.b.c to relocated.a.b.c (except for the explicit pattern I excluded).
It appears that the relocation process moves all references to classes that match that pattern, regardless if that class is defined within a dependency used to construct the jar.
The following stack trace (obtained from trying to run a main() defined in a jar that was constructed using the relocation above) shows that a reference to java.lang.Object was renamed to relocated.java.lang.Object, and that (obviously) the relocated. version can't be found.

Exception in thread "main"
I am trying to create the concordion-extensions-demo (located at http://concordion.org/Download.html) project with Maven.
When I run the command mvn test I receive errors ...

In the POM there are variables for ..
concordion.version, concordion-extensions.version and slf4j.version.
Do I need to update these tags with actual version numbers?
As is probably obvious I am not an experienced software devoloper or have much experience with Maven. Does anyone have an idea as to what the problem could be and how I could resolve this?
Thanks.
Tam.
