SourceTypeCollisionException in Eclipse project

[Dave Borowitz]

I reproducibly get this uncaught exception in the Eclipse compiler when building Gerrit on Mac. Anybody seen it before?

It only happens on Mac and on Neon, not Mars/Oxygen (prerelease). Things seem to have compiled except for some of the AutoValue classes weren't generated.

This used to happen on my old laptop; I just got a new laptop yesterday and it still happens, with a completely fresh OS+Eclipse install and everything.

looks similar to

[Dave Borowitz]

Yeah, seems like upstream doesn't care about it though, and that bug doesn't suggest any workarounds.

[Matthias Sohn]

I asked Dani Megert to have a look

[Dave Borowitz]

Thanks Matthias :)

Yes. Alan Tokaev had that problem, and he solved that by checking one

check box in Eclipse setting related to annotation processing. I forgot what

it was.

Here is the response from Dani. 

Can you comment in

Bug 469031: SourceTypeCollisionException escapes from compiler

and provide steps to reproduce ?

Hi Matthias

This is most likely caused by a bug in the compiler when it processes annotations (APT). I suggest to post a comment into

Bug 469031: SourceTypeCollisionException escapes from compiler

Best with steps.

[alan Tokaev]

Hi,

I can't find my old mail with a comprehensive description. Just play with annotation processing settings in this area of project properies:

I tried

 - DmaxCompiledUnitsAtOnce=1000000

and they do not work

[Bruce Zu]

restart Eclipse does NOT apply the update

close Eclipse and starts it again. it works now.
