Stephen Haberman created IVYDE-322:
--------------------------------------
Summary: incomplete xml files causing parse exceptions
Key: IVYDE-322
URL: https://issues.apache.org/jira/browse/IVYDE-322
Project: IvyDE
Issue Type: Bug
Affects Versions: 2.2.0.beta1
Environment: ivy 2.2.0
Reporter: Stephen Haberman
We're getting occasional build failures where Ivy seems to be trying to read
only partially-complete XML files from the cache.
This happens only on our Hudson box, when it's running ~4-5 builds at a time,
so my theory is that the separate Ivy processes are not blocking each other
from reading incomplete files--just restarting a job makes it work the second
time, so it's a very transient error.
Stack trace is below. Does it seem likely that RetrieveEngine's
determineArtifactsToCopy is missing some locking/ordination around line 286/288
where it uses cacheManager to get a file and then parse it?
