I have tried the example at wiki.eclipse.org/Acceleo/Maven but cannot make the plugin
Version 3.2.1. running without error. I always get the following message:

[INFO] Failed to configure plugin parameters for: org.eclipse.acceleo:maven:3.2.1
Cause: Class 'java.util.List' cannot be instantiated

Here is what i did:
* I downloaded R3.2.1.zip from http://git.eclipse.org/c/m2t/org.eclipse.acceleo.git/refs/
* Extracted the project org.eclipse.acceleo.maven.tests from it.
* In the pom I changed some minor things to make it run:
** removed the -SNAPHOTS
** Changed the repo and plugin repo settings as given on the wiki page
** added <usePlatformResourcePath>Indigo</usePlatformResourcePath> in the configuration.
* Of course I tried that first in my project, but had the same problem.
* I tried it with both Maven 2.0.9 and 2.2.1 and get the same error

I will attach the output of the command
mvn clean org.eclipse.acceleo:maven:3.2.1:acceleo-compile compile verify -X

Anyone have the same problem or a solution?

I' like to try with version 3.3.0 but somehow cannot manage to download it in maven.
Just increasing the version number seems not sufficient.

Hi,

Could you please post here the configuration of the Acceleo plugin in your pom.xml?

It is as i described in the text (see attached file).
I also used another jdk today, but the output is identical, except for JAVA_HOME and some other IMHO minor stuff.
I cleaned the org.eclipse branch of my local repo but the result is the same.
I would also try the latest plugin version 3.3.0, but from which mavenrepo can I get it?
Thanks for your help,
Christian

Hi,

I too am having problems with org.eclipse.acceleo:maven:3.2.1 in maven

I'm getting, java.lang.NullPointerException at
org.eclipse.acceleo.internal.parser.ast.CST2ASTConverterWithResolver.getProtectedTemplatesNamed(CST2ASTConverterWithResolver.java:654) at org.eclipse.acceleo.internal.parser.ast.CST2ASTConverterWithResolver.getExtendedTemplatesNamed(CST2ASTConverterWithResolver.java:607) at org.eclipse.acceleo.internal.parser.ast.CST2ASTConverterWithResolver.transformStepResolve(CST2ASTConverterWithResolver.java:488) at org.eclipse.acceleo.internal.parser.ast.CST2ASTConverterWithResolver.transformStepResolveOwnedModuleElement(CST2ASTConverterWithResolver.java:1781) at org.eclipse.acceleo.internal.parser.ast.CST2ASTConverterWithResolver.transformStepResolve(CST2ASTConverterWithResolver.java:198) at org.eclipse.acceleo.internal.parser.ast.CST2ASTConverterWithResolver.resolveAST(CST2ASTConverterWithResolver.java:136) at org.eclipse.acceleo.internal.parser.ast.CST2ASTConverterWithResolver.resolveAST(CST2ASTConverterWithResolver.java:115) at org.eclipse.acceleo.parser.AcceleoSourceBuffer.resolveAST(AcceleoSourceBuffer.java:336)
....

any ideas?

it might be related to the use of template overrides,
I have more than one template overriding another....if I remove some of them,
the error goes away....but this may be a red herring.

cheers

Update,

found the issue.

some of my mtl templates were using 'http://www.eclipse.org/uml2/4.0.0/UML'
and some were using 'http://www.eclipse.org/uml2/3.0.0/UML

some better error reporting be acceleo would be nice here Smile
