What does "Deduplicating compilation" mean?

[davidmlw]

moduleA depends on moduleB, and moduleB depends on moduleC.

bloop compile moduleC
bloop compile moduleB
bloop compile moduleA

in sequence, should work exactly as

bloop compile moduleA

While because the sequence was emitted from a flow tool, it might be too fast or parallel, bloop will complains "Deduplicating Compilation of moduleC".

It seems that "Deduplicating Compilation" didn't go wrong or multiple random classesDir.

@davidmlw Deduplicating compilation means that a compilation triggered by another client is reusing the compilation happening by another client. This can happen when Metals triggers a compilation and you're compiling/testing/running with the bloop CLI. It works as expected and means that bloop is making good use of resources.
