this is exactly what I have tried to do. This will really look ugly :/
I will write it as clear as possible:
in pom.xml I added:
<dependency>
<groupId>org.mvel</groupId>
<artifactId>mvel2</artifactId>
<scope>compile</scope>
</dependency>
On forge install-plugin ~/blabla/ I get:
***SUCCESS*** Installed from [plugin-faces-idaware] successfully.

So to me it is clear, that I was successful, integration of Mvel libraries is done.
But when I invoke my plugin, I get _a LoaderConstraintViolation_!!
[myidaware] myidaware $ set VERBOSE true
[myidaware] myidaware $ scaffold from-entity at.tfr.test.model.* --scaffoldType idaware
Use which scaffold provider?
1 - [idaware]
2 - [faces]*
? Choose an option by typing the number of the selection [*-default] [0] 1
***ERROR*** [scaffold from-entity] loader constraint violation: loader (instance of org/jboss/modules/ModuleClassLoader) previously initiated loading for a different type with name "org/mvel2/templates/CompiledTemplate"
org.jboss.forge.shell.exceptions.CommandExecutionException: loader constraint violation: loader (instance of org/jboss/modules/ModuleClassLoader) previously initiated loading for a different type with name "org/mvel2/templates/CompiledTemplate"
Caused by: java.lang.LinkageError: loader constraint violation: loader (instance of org/jboss/modules/ModuleClassLoader) previously initiated loading for a different type with name "org/mvel2/templates/CompiledTemplate"
So for me it is evident, that I brought my own Mvel jar, but the module loader will not let me use it!
