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)
       at com.hikuku.rules.util.TestHelperRules.getPackage(TestHelperRules.java:85)

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>

                   <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
