[hibernate-dev] Gradle, ORM and Mac OS X

[Emmanuel Bernard]

I had a lot of hurdles to make Hibernate ORM run and build on Mac OS X and IntelliJ IDEA so here are a few tidbits:

I give Gradle 1GB 

    export GRADLE_OPTS="-Xmx1024M"

Gradle hangs on me after ~ 2300 to 2400 tests for hibernate-core subsystem. Basically at least one of the worker hangs for ever.
To work around that I forced Gradle to use one thread

    ./gradlew -no-daemon --parallel-threads 1 clean test

IntelliJ IDEA does not import ORM properly on Mac OS X. I tried both to run IDEA with Java 6 (default) and Java 7 (hacked). The way around that is to use `./gradlew idea` and open the project in the IDE. You then have to manually add the generated source directory in a few modules.
