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/ *** stop. Stop.

So I made a little change to the file: /replicant-4.2/build/core/
(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:

host Java: guavalib (/home/misc/dev/replicant-4.2/out/host/common/obj/JAVA_LIBRARIES/guavalib_intermediates/classes)
warning: [options] bootstrap class path not set in conjunction with -source 1.5

reason: actual and formal argument lists differ in length
where T is a type-variable:

1 error
4 warnings
make: *** [/home/misc/dev/replicant-4.2/out/host/common/obj/JAVA_LIBRARIES/guavalib_intermediates/javalib.jar] Error 41
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.

It's very likely too much work to patch Replicant 4.2 to make it work with Java 1.8. However, the current development version Replicant 6.0 builds fine with Java 1.8, at least on Debian Stretch.
