regression: CrossVersion.patch not found during extraction

[SethTisue]

a few projects have started to use CrossVersion.patch which is new in sbt 0.13.13

the community build is on 0.13.13, so that shouldn't be a problem. but for some reason (source):

this seems mystifying. it says [macro-compat] Using sbt version: 0.13.13. And we also see <<= operator is deprecated which deprecation didn't happen til 0.13.13, so that is additional evidence that 0.13.13 is being used. so how can we possibly be getting patch is not a member of object sbt.CrossVersion?

[SethTisue]

@cunei @dwijnand any ideas?

[dwijnand]

At a guess I think this issue and the Resolver.binraryRepo issue are one and the same. Something funky with what's on the classpath is happening. I don't know what.

[SethTisue]

the Resolver.binraryRepo issue

@dwijnand what issue is that?

[dwijnand]

See #264 (comment)

[cunei]

If I can I will investigate; I am hacking on dbuild right now, so I might as well do some debugging concerning this matter.

[cunei]

I did some debugging, and I found that some sbt 0.13.0 jars end up on the classpath, dragged in by the dbuild plugin. During the metabuild resolution, sbt prints:

[info] Resolving org.scala-sbt#io;0.13.0 ...
[info] Resolving org.scala-sbt#control;0.13.0 ...
[...]
[info] Resolving org.scala-sbt#io;0.13.13 ...
[info] Resolving org.scala-sbt#control;0.13.13 ...

and in the end both end up on the classpath. It is a bit messy, I will have to study the situation for a bit.

[cunei]

@SethTisue This should be fixed in 0.9.7-RC1, can you please try it?

[SethTisue]

@cunei fantastic! I will try it soon
