Is it ok to run gtest only when testing Java?
You could then do linkDebug and get *.so file without running gtests. Is this the intention?

For CI I think this does make any difference - the gtests will run a bit later. For local dev, you can use -Pskip-gtest gradle paramater.

The rest of the changes looks good.

...

For me, it is more idiomatic to have tests run in the test step. I found it confusing to have always test that run at every build.
We can still call it explicitly with gtest and they are linked in the testDebug steps.

Though I agree this is a matter of taste.

Though I agree this is a matter of taste.

It's mostly about whether we feel it is ok to be able get the library binary without going through the gtest by default.
I have no strong opinion in this case - as long as we run the gtests eventually :)

I had issues with file ownership on some alpine builds. I'm not sure why I was the only one to see this.
