Java 7 support in Drools Eclipse plugin --------------------------------------- Key: JBRULES-3458 URL: https://issues.jboss.org/browse/JBRULES-3458 Project: JBRULES Issue Type: Enhancement Components: drools-eclipse Affects Versions: 5.3.0.Final Reporter: Jan Gaspar Assignee: Mario Fusco Labels: eclipse, jdk7 I created a Drools project in Eclipse (Indigo) configured to use JRE 1.7. But I get an error pointing to my .drl file: com/sample/DroolsTest$Message : Unsupported major.minor version 51.0 The com.sample.DroolsTest.Message class is imported by the .drl file. The Drools runtime was 5.2.1 (also tried with 5.3.0.Final). Apparently Drools eclipse plugin expects the fact classes to be compiled with JDK6. Is there any way to make the plugin working with JDK7 compiled classes?
