Hello,
I currently developing an additional component, this component need 3rd
party jars to run.
I have included my project in Eclipse, where I stored the jars in the
build path.
To create the jar with Maven works without error.
Whenever I install my component in xwiki.basedir {} / WEB-INF/lib, and
then try to execute this in Velocity in a page I get the following error
displayed:
Caused by: org.apache.velocity.exception.MethodInvocationException: Invocation of method
'createProjectPages' in class com.acme.internal.BlueAntComponentScriptService

I've tried to make the jars available via the command:
mvn install:install-file -Dfile=src\main\resources\axis.jar
-DgroupId=axis -DartifactId=axis -Dversion=1 -Dpackaging=jar
...
...
...
But this has not helped.
My pom file looks like:

Can anyone help a desperate trainee? :)
