Incompatibility with the last version of truth

[BraisGabin]

I'm getting this exception after update the version of truth updates:

The last version of truth updates guava and I think that is the issue.

Here is the PR that shows this issue: SchwarzIT/dagger-lightsaber#3

Thanks. This is a general issue with any project that depends on guava-jre but also depends on a project that depends on guava-android :( The workaround is to declare a dependency on the newest version of guava-jre (currently 32.1.1-jre). (And then presumably Renovate will automatically keep you up to date with the latest guava-jre, preventing the problem from arising again, at least as long as you bump the Guava version each time before you bump the Truth version.)

We recently put some magic in place to make Gradle pick the right version automatically, but there's no similar solution for Maven.

It's possible that we can still make things better, either by releasing separate, Guava-style truth:1.1.6-android and truth:1.1.6-jre "versions" (which would be identical except for their Guava dep) or by making guava-android contain APIs like MoreCollectors. I'm hoping that we'll at least make some progress on the latter front later this year. You can follow google/guava#6567. Sorry for the ongoing trouble in the meantime.
