Question

After downloading the SBT source and running the SBT shell:

$ mkdir sbt-modules
$ cd sbt-modules
$ for i in sbt io util librarymanagement zinc; do \
  git clone https://github.com/sbt/$i.git && (cd $i; git checkout -b develop origin/develop)
done
$ cd sbt
$ ./sbt-allsources.sh

When I publish, I get the following error:

sbt:sbtRoot> publishLocalAllModule

This is after:

Deleting my ~/.sbt directory recursively
Running git clean -dfx to delete all untracked and ignored files in each SBT repository

This is the head of the branch for the sbt/sbt project that was checked out when I ran the for loop above, which I did just now:

Answer 1

我相信zinc/pull/577违反了publishLocalAllModule。分析diff，我们发现它来自

- compilerBridge,

到

+ compilerBridge210,
+ compilerBridge211,
+ compilerBridge212,
+ compilerBridge213,

但是publishLocalAllModule仍然仅指compilerBridge：

  ...
  val csv = get(crossScalaVersions in ProjectRef(build, "compilerBridge")).toList
  (csv flatMap { bridgeSv =>
    s"++$bridgeSv" :: ("{" + build.toString + "}compilerBridge/publishLocal") :: Nil
  })
  ...

用compilerBridge代替compilerBridge212，我们可以使publishLocalAllModule继续进行，但是以后仍然失败。我认为值得举一个官方issue来要求更新publishLocalAllModule。

Running `publishLocalAllModule` on SBT source says `crossScalaVersions is undefined` for `zinc`
