Hi Everyone, I've seen this issue in the archives, but I haven't seen anyone address it in regards to an upgrade from 4.07 to 5MR2. Basically, I have a set of java dialect "drl" files that compile properly in 4.07 and are usable, but when I simply modify my maven build to use the 5MR2 release, I get the following well-known error: Caused by: java.lang.RuntimeException: The Eclipse JDT Core jar is not in the classpath at org .drools .rule .builder .dialect .java .JavaDialectConfiguration.setCompiler(JavaDialectConfiguration.java: 94) at org .drools .rule .builder .dialect .java.JavaDialectConfiguration.init(JavaDialectConfiguration.java:55) at org .drools .compiler .PackageBuilderConfiguration .addDialect(PackageBuilderConfiguration.java:200) ... 30 more This error seemed to go away when I moved from using my local build of Drools to using the staged builds on snapshots.jboss.org, but has come back to haunt me this morning. Have the transitive dependencies changed in 5? Are there any Maven specific work-around suggestions? Is this the expected behavior for 5? best wishes, Andrew --------------------------------- Andrew Waterman San Cristóbal de las Casas, Chiapas, Mexico +52 1 967 103 3176 +1 510 342 5693 _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
