steps: create j2se with main class add entity class (new|entity) use attribute of metamodel type (entity name with '_' at the end) in main class try to run the project got dialog about "one or more projects was compiled with error". reproducible with web project also (see 181693)
this dialog will appear once if source level is set to jdk5 and twice if source is set to jdk6
if I use metamodel from the same package I got only dialogs but main class is executed after "run anyway" selection, but if I use metamodel from another package I have "run: Exception in thread "main" java.lang.ExceptionInInitializerError Caused by: java.lang.RuntimeException: Uncompilable source code - cannot find symbol symbol: class NewEntity2_ location: package fff at javaapplication4.Main.<clinit>(Main.java:8) Could not find the main class: javaapplication4.Main. Program will exit. Java Result: 1 BUILD SUCCESSFUL (total time: 2 seconds)" looks more like p2 for me now.
The reason of this is following: The clean & build works as it uses the ant script. The run file works when Compile on Save is disabled. The problem is when CoS is enabled and Run Processor in editor is disabled. The CoS just copies files from cache but the generated files are not available as the processors are disabled. The solution is to enable processors in editor by default, I will do it for j2se project. There will be 2 cases: 1st) When new j2se project is created the ANNOTATION_PROCESSING_ENABLED_IN_EDITOR will be true. This handles new projects. 2nd) When PU is added into the j2se project it will enable ANNOTATION_PROCESSING_ENABLED_IN_EDITOR if it's disabled (covers already created projects). The same needs to be done for web project. I will attach a link to j2seproject diff.
