Lincoln, frankly, I'm stumped by this one. I never received a
LoaderConstraintViolation or anything similar. My issue was with
the seam-render not being added as a module to the plugin, since it
was already included with the Forge core. However, that issue has
since been resolved.<br>
<br>
Thomas, I'm not sure of the cause of your exception, as including
seam-render and MVEL as dependencies solved the problem for me. If
I understand your most recent e-mail correctly, your problem is
solved if MVEL is manually added to module.xml? MVEL is not
required for my ScaffoldProvider implementation, so maybe you are
experiencing a similar problem?<br>
<br>
Sorry,<br>
Ryan<br>

Thomas, perhaps you could try including seam-render instead of
MVEL? Make sure you use the same version that Forge Shell uses as
a temporary workaround.<br>

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

So to me it is clear, that I was successful, integration of
Mvel libraries is done.<br>
But when I invoke my plugin, I get _a
LoaderConstraintViolation_!!<br>
<br>
[myidaware] myidaware $ set VERBOSE true<br>
[myidaware] myidaware $ scaffold from-entity
at.tfr.test.model.* --scaffoldType idaware<br>
Use which scaffold provider?<br>
<br>
1 - [idaware]<br>
2 - [faces]*<br>
<br>
? Choose an option by typing the number of the selection
[*-default] [0] 1<br>
<div class="im">***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"<br>
</div>
org.jboss.forge.shell.exceptions.CommandExecutionException:
loader constraint violation: loader (instance of
org/jboss/modules/ModuleClassLoader) previously initiated

"org/mvel2/templates/CompiledTemplate"<br>
<br>
Caused by: java.lang.LinkageError: loader constraint

org/jboss/modules/ModuleClassLoader) previously initiated

<br>
<br>
So for me it is evident, that I brought my own Mvel jar, but
the module loader will not let me use it!<br>
