> We have a few build processes running in parallel, all of which share the
> same ivy cache. In order not to run into any parallel downloading problems,
> we enabled artifact-lock lock strategy. An annoying problem with the
> artifact-lock strategy is that the *.lck files which are created as a lock
> are not cleaned up if the build exits abruptly. For example, while ivy is
> downloading a big jar, if you Ctrl-C to quit that build process. Those lock
> files will remain in the metadatas folder. The same happens too if ivy
> encounters some error and fails the build.
> Those uncleaned lock files will cause problem when you start the build again.
> The build process will hang while ivy waiting those "locks" to be released,
> which will never happen automatically. So eventually the build will fail with
> an ivy error "impossible to acquire lock for xxxyyyzzzz". What makes it worse
> is that ivy doesn't fail-fast on the default 2 miuntes lock timeout, it seems
> trying it a few times. In worst scenarios, we have seen the build hangs for
> 12 minutes and then timeout'd and failed.
> We believe this can be fixed by setting deleteOnExit() for the
> FileBasedLockStrategy.java class. We have implemented the fix and it works
> well.
> Patch is provided, could anyone quickly apply this one line change?
