Concurrent Resolve Failures

[Kevin Formsma <ke...@leanlogistics.com>]

Hello!

I have a large complex build that I’m using Ivy to resolve dependencies for. Within a single build, there are concurrent ivy resolves taking place in separate modules due to the use of Ant’s Parallel task. I’ve updated my cache to use the ‘artifact-lock’ strategy and I’ve also disabled the memory cache:

<caches default="lockingcache">
    <cache name="lockingcache" lockStrategy="artifact-lock" memorySize="0"/>
</caches>

I’m running into errors still when these resolves occur at the same time. I’ve seen two different errors:

1. java.lang.RuntimeException: problem during retrieve of organization#module: java.text.ParseException: failed to parse report: .ivy2/cache/xxxx-xxxx-provided.xml: For input string: ""
2. “impossible to acquire lock for XXXX” occurs because the .lck file doesn’t get cleaned up. I’m not sure how to reproduce this, but it may be a bad state due to error #1. Manually deleting the lock file cleans this up.

Any ideas on what to try? I don’t believe I need separate resolution caches, because I’m not resolving the same module at the same time. It doesn’t happen every build, but seems to be intermittent.

Thanks!
-Kevin
