Re: [rules-users] NPE after rule consequence executes

After the build, you can find the jars in: drools-core/target drools-compiler/target Their version must always match or you will end up with other problems. []s Edson 2008/4/9 Scott Reed <sreed(a)avacoda.com <mailto:sreed@avacoda.com>>: I built it but can only find the core jar file, nothing for the compiler. With just the core jar replaced, I still get the NPE.
