SBT reload fails on SNAPSHOT which are republished locally *while SBT runs*

See original GitHub issue

I’m developing a SBT plugin and testing it by reloading in a project using it. The reload however fails, complaining about corruption of the plugin JAR file, and I must exit and re-enter the client SBT project; this happened with SBT 0.13.0 in the client, and 0.12.4 in the SBT used for development.

The first time, the client SBT complained that it can’t find sbt/sbt.plugins within the JAR. But unzip confirms the entry is there; exiting and re-entering SBT in the client project fixes the problem. The second time, the error was different, but again unzip -t confirms that the JAR is fine. The third time, the error was yet different, but again about ZIP corruption.

Note that before the failed reload, lsof reveals that SBT has two file descriptors pointing at the JAR of the plugin, while afterwards it has three or four file descriptors. My suspect is that it does not reopen the JAR file from scratch, but tries to reuse some old info about it.

To support this hypothesis, this only happens if settings from the plugin are actually used (by putting seq($thisPluginSettings: _*) in build.sbt).

Steps to reproduce in my case:

git clone git@github.com:softprops/np.git
cd np
# edit build.sbt, set version to 0.2.1-SNAPSHOT
# edit plugins/plugins.sbt, comment out gpg plugin
sbt
> publish-local
# Close this or leave it open, we'll need it later.
# Go to another project, even a fresh one
# in project/plugins.sbt, add:
addSbtPlugin("me.lessis" % "np" % "0.2.1-SNAPSHOT")
# in build.sbt, add:
seq(npSettings: _*)
# Start sbt
# Go back to first console, reopen SBT or reuse the existing session (it doesn't matter), modify some source to force recompilation, perform publish-local
# Go back to second console
# Try using the plugin, it still works if used before, otherwise gives ClassNotFoundException.
# Try a reload, get some error about corruption of the ZIP file, for instance:

> reload

+1 I know this has been ignored mostly but has anyone found a workaround? The only workaround I have today is to restart sbt

This makes testing newly published plugins locally, in a “real” SBT project (e.g. not a sbt-scripted test project) very difficult.
