Re: [m2e-users] JPA 2 metamodel Generation

Interesting... apparently maven-compiler-plugin does support annotation
processing out of the box. Feel free to open enhancement request to add
this to m2e, but somebody will have to provide a quality patch for this
to happen before m2e 1.0. It should be possible to add this support via
external m2e extension, so the patch does not have to change the core.

I am attaching a complete standalone example. Just run mvn test from the
command line and everything works fine - you will see generated code
in target\generated-sources. However if you bring up the project in
Eclipse, the ArtistRepository class will have two errors because the
generated code is not visible.

    Complete standalone sample project would be useful here.

    I am guessing somebody will have to develop what we call "project
    configurator" before this will work inside m2e, but I want to make sure
    I am not missing anything.

        Reading the instructions

        at the hibernate site, I tried to enable annotation processing
        and add
        the Hibernate Metamodel Generator to the factory path. This started
        generating the metamodel, but Eclipse started going into an infinite
        loop trying to compile the sources. So this didn't work either.

        Can someone please help me with this issue? I am using m2eclipse
