Play Framework commands abort with ZipException

Question

After a Windows 7 crash my Play framework project seems to be broken.

My version:

play --version
sbt launcher version 0.12.2

Running any play command in my project folder gives this error:

C:\dev\myproject>play clean
[info] Loading project definition from C:\dev\myproject\project

Googling did not help. The stacktrace does not help me either, it doesn't say which file/resource causes that. I have not made any changes to the project. The only "difference" is the Windows crash, possibly while some play command was running.

Re-created play installation... same error.

Answer 1

I just spent the last 4 hours trying to fix this error and it turned out that another folder in my home directory(ubuntu) was named project. Renaming this folder solved this issue for me.

Answer 2

To fix this you have to delete the "project" and "target" folders. They can be found in another folder called "project" in your play-project.

Answer 3

Dunno what caused it, or how to properly solve it. And a meaningful exception would be nice.

But the workaround for me was to get a new checkout from version control.
