GWT 2.3 that we use doesn't support java 7 syntax. The latest version, 2.5, doesn't either. I'm not sure, however, this is a good reason to enforce the java 6

i agree. you can limit it to the parts used by GWT for now. The major advantage to move to java7 is the try-with-resources statement.
If we can do this for 3.2 it will be great. From what I understand from Allon, the only noisy change is to move the common and compat out of the backend directory into its own top-level directory, so we can apply a different maven policy on these two easily.
This way the common/compat and frontend will be built using 1.6 and backend will be built using 1.7.
and searchbackend. asaf, is there no easier way to enable java 7 compilation/enforcement except for these 3? In the long run consider having a project layer such as : Frontend / Backend / Shared [common/compat/searchbackend] , this will allow us to use plugins inheritance cleanly [regarding versions],
Of course inheritance is nicer but it requires a lot of movements (maybe in v4?)
For now its easy - we can just use the maven-compiler to define source/target of [v1.7] for the root project, while defining explicitly different versions per frontend/shared module [v1.6] Checkstyles should be upgraded as well. _______________________________________________ Engine-devel mailing list Engine-devel@ovirt.org http://lists.ovirt.org/mailman/listinfo/engine-devel
