Description

I tried to compile Replicant 4.2 with Oracle Java 1.8.0 update 60 installed (on a x86_64 GNU/Linux desktop operating system).

The pre-check says:

Checking build tools versions...
****************************************************
You are attempting to build with the incorrect version
of javac.
Your version is: javac 1.8.0_60.
The correct version is: 1.6 or 1.7. ****************************************************
build/core/main.mk:133: *** stop. Stop.

So I made a little change to the file: /replicant-4.2/build/core/main.mk
(the patch file 'add-1.8-to-javac-correct-version-check.patch' is attached).

After that the build process starts and run for some hours, but finally breaks on:

I've found some links to that topic:

but they don't provide any solution.

After searching through this:

I fear, there could be waiting more work, (e. g. merging an updated guava version). Then I don't know if it's worth the trouble.

So for now, I switched back to Oracle Java 1.7.0 update 80 and everything compiles great (with some insignificant warnings).

But if there would be an easy way to compile with a newer Java version, I would be really glad to get any hint to do so.
