[jira] Created: (IVY-701) NPE while resolving dependencies
NPE while resolving dependencies
--------------------------------
Key: IVY-701
URL: https://issues.apache.org/jira/browse/IVY-701
Project: Ivy
Issue Type: Bug
Components: Core
Affects Versions: 2.0.0-beta-2
Reporter: Nicolas Lalevée
I have build the trunk of Ivy today in order to be used in IvyDE : svn revision 611768
And a resolve threw a NPE :
{noformat}
com.company#project;latest.development: java.lang.NullPointerException at org.apache.ivy.plugins.resolver.AbstractResourceResolver.findResource(AbstractResourceResolver.java:161)
{noformat}
With the command line, with ant, I still use Ivy1.4, and it works.

[jira] Commented: (IVY-701) NPE while resolving dependencies

Nicolas Lalevée commented on IVY-701:
-------------------------------------
I have just changed the ivy.conf used by eclipse so it use a specific cache, unrelated to the cache used by our command line build which use Ivy1.4. It works like a charm, and some strange behavior disappeared : in the resolved dependencies there were the same library retrieved twice with two different versions.

Xavier Hanin commented on IVY-701:
----------------------------------
I've just checked in what should fix the NPE. I haven't found an easy way to add a unit test to reproduce the problem though, so my fix is based on code analysis only. Could you try out the latest trunk version and tell me if you still get the NPE or not?

Updated Ivy to the revision 612380. Now I have :
{noformat}
com.joost#openrdf-adapter;latest.development: not found
{noformat}
So it seems that Ivy2 is not fully backward compatible with Ivy1. Maybe this topic may deserve a specific page in the doc ?

Xavier Hanin commented on IVY-701:
----------------------------------
The cache structure has changed between 1.4 and 2.0, so I don't recommend sharing the cache between the two. But this shouldn't end up in a NPE in any case, so the bug is valid.

[jira] Resolved: (IVY-701) NPE while resolving dependencies
Posted by "Xavier Hanin (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/IVY-701?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Xavier Hanin resolved IVY-701.
------------------------------
Resolution: Fixed
Fix Version/s: 2.0.0-beta-2
OK, so now the error is slightly better (anything is better than NPE :-)), and I guess that with debug level messages you would have more details, helping to diagnose the problem comes from using the same cache for Ivy 1.x and 2.x.
So the only remaining issue IMO is to document the cache incompatibility.

-------------------------------------
Or is this my fault is trying to use both Ivy 1.4 and Ivy 2 on the same cache ?

Updated Ivy to the revision 612380. Now I have :
{noformat}
com.company#project;latest.development: not found
{noformat}
So it seems that Ivy2 is not fully backward compatible with Ivy1. Maybe this topic may deserve a specific page in the doc ?
