RE: [rules-users] Error compiling rules (3.1M1). NoSuchMethodError: EclipseJavaCompiler.<init>(java/util/Map)

COMPILER - rule assembly time Rule compiler takes rules in some textual format and prepares binary Packages of rules for deployment. This depends on the CORE RUNTIME. * drools-core * drools-compiler - the rule compiler itself. * antlr3 - only if you are using native DRL. if only using XML, you can skip this. * xerces, xml-apis - only if you are using XML rules, if DRL only, can skip this. * commons-jci-core o This also requires only one pair out of: + commons-jci-eclipse, core-3.2 - for eclipse JDT to compile the java semantics (this is default) + commons-jci-janino, janino - for janino. To use this option, set -Ddrools.compiler=JANINO or use PackageBuilderConfiguration? class. * commons-logging - used by various dependencies. * commons-lang - used for string manipulation in various dependencies. * stringtemplate, anlr-2.7.6 - used in generating semantic code.

NoSuchMethodError: EclipseJavaCompiler.<init>(java/util/Map) Thank you, Tom. I replaced antlr-2.7.6 with 2.7.7 and antlr 3.0ea8 with the 3.0b5 that came with the Drools 3.1M1 release. I upgraded stringtemplate to 3.0. None of these changes helped which is not too surprising since the error is in the commons-jci code: Exception in thread "main" java.lang.NoSuchMethodError: org.apache.commons.jci.compilers.EclipseJavaCompiler.<init>(Ljava/util/M ap;)V. I have a critical question. If you removed commons-jci-eclipse-3.2.0.666.jar, what did you replace it with? Since the error I am getting is in that jar, I am very interested in this answer. There is no version of that jar in the 3.1M1 release. If anyone else can weigh in here and enlighten me I'd appreciate it.
