Sean Busbey updated HBASE-21808:
--------------------------------
Status: Patch Available (was: In Progress)
v0
- adds jdk profiles to add J2EE dependencies that were removed in JDK11
- makes the spotbugs stuff 1.8+ instead of 1.8 exactly
- can successfully pass {{mvn -DskipTests --batch-mode -e install
assembly:single}}
- resultant java class files report they are JDK1.8 compatible
This would at least allow new contributors for *most* patches to get a build.
Haven't tried any tests; I don't think anything with e.g. minicluster would go
well.
The binary tarball that results from this assembly fails to launch a standalone
cluster (running with JDK8). Haven't finished figuring out why yet. It's all
problems for netty so I suspect something has messed up the lib directory.
> Ensure we can build with JDK11 targetting JDK8

> When folks "install a JDK" wether they get JDK11 now will depend on the
> platform (e.g. from homebrew you will get jdk11). For new contributors this
> results in confusing errors on first run.
> Make it so that a non-release build using JDK11 and using our default
> compiler source/target versions of JDK8 can complete.
