Thank you so much! I checked out the trunk via SVN, and it did build for me. However, when I moved the runtime jars (including the dependencies outlined in the README files) into my project, I started seeing this error when I try to load up some DRL rules:
java.lang.NoSuchFieldError: recognizer at org.drools.lang.DRLLexer$DFA18.<init>(Unknown Source) at org.drools.lang.DRLLexer.<init>(Unknown Source) at org.drools.compiler.DrlParser.getParser(Unknown Source) at org.drools.compiler.DrlParser.parse(Unknown Source) at org.drools.compiler.DrlParser.parse(Unknown Source) at org.drools.compiler.PackageBuilder.addPackageFromDrl(Unknown Source) I copied the antlr2 jar from the SVN checkout, but I don't see an antlr 3 jar, so I'm using the version from the 3.0.3 binary distribution. Any idea what I'm doing wrong?
