[rules-users] problem in Maven tests: class antlr CharStream not found, although it is there!

[tim tim]

hello all

my problem is that my tests work fine in eclipse, but they
don't work in maven.

when i execute my code via

     mvn test

drools cant find the antl CharStream class.

this is the error i get:

java.lang.NoClassDefFoundError: org/antlr/runtime/CharStream
	at org.drools.compiler.PackageBuilder.addPackageFromDrl(PackageBuilder.java:276)

i have the antlr3.jar in my dependencies via the drools-compiler  pom.xml
and the class  org.antlr.runtime.CharStream is definitely in the classpath.
i can use it from my own code without problems.

but the drools package builder does not seem to find it.

this works (even under maven):

     final int a = org.antlr.runtime.CharStream.EOF;

but this doesn't find CharStream:

     PackageBuilder builder = new PackageBuilder();
     builder.addPackageFromDrl(r);


this is my dependency on drools as i have it in my pom:

            <dependency>
		    <groupId>org.eclipse.jdt</groupId>
		    <artifactId>core</artifactId>
		    <version>3.4.2.v_883_R34x</version>
	    </dependency>
	
	    <dependency>

		    <groupId>org.drools</groupId>
		    <artifactId>drools-compiler</artifactId>
		    <version>5.0.0.SNAPSHOT</version>
	    </dependency>


the snapshot i use is the drools-5.0.0.20090203.112022-386


does anyone have an idea what the problem might be?

thanks, tim
