Why isn't Drools working with Java 8?

Question

I just installed the final version of Java 8. When I try to build my project with Maven, many tests fail if I use Java 8, but pass fine with Java 7. I\'ve tried running it

Answer 1

Looks like a bug in Drools (in the Eclipse compiler which is the default):

• Bugzilla
• JIRA (thanks Laune)

They're looking into fixing it in 6.1.0.Beta2.

Meanwhile, try this workaround: Override the ecj dependency to version 4.3.1.
