Gilles Scokart updated IVY-1059:
--------------------------------

      Priority: Major  (was: Critical)
    Issue Type: Improvement  (was: Bug)
       Summary: Incorrect usage of the resolution cache should be reported nicely  (was: Incorrect branch information is taken during publish)

Hudson launch a new JVM for each build.  So it can not be a static value in memory.  If the branch name leak from one build to the other build, that must happen via the file system.  Most probably for the resolution cache as Maarten said.

I identified a probable flow.  The resolve stores the resolved module descriptor in the resolution cache (containing the branch info contained in your original ivy file).  When you publish, ivy take the module, the organisation and revision from the ant properties defined by the resolve.  It use this info to find back the resolved module descriptor in the resolution cache.  If the file has been replaced by an other build, you have a problem...
So really, if you have concurrent build, you should use a different resolution cache.


I reduce the severity.  Feel free to increase it again if you still have the problem whit separate resolution cache.

I didn't close it, because I think we should find a way to ensure that the content of the cache is the right one.  But I don't see a nice solution for the moment.
Also, we should maybe use a default directory that is no global (something relative to the build directory maybe).  But for that I don't see a good choice for the moment.

> I have 2 ant builds for the same project running in hudson build environment. One build is for branch="" second for branch="1.0".
> Branch information is configured in *.ivy files for this projects.
> Problem is that if this builds are started at the same time, one build takes a branch information from the other build. 
> I don't understand how could this happened. Looks like there are some static configuration is set in ivy .
