David Schlosnagle commented on IVY-1028:
----------------------------------------
I am also encountering the {{IndexOutOfBoundsException}} triggered by
{{org.apache.ivy.plugins.resolver.IBiblioResolver.findSnapshotVersion(IBiblioResolver.java:165)}}
using Apache Ivy 2.1.0-rc1. The problem appears to only occur when using the
Ibiblio resolver when no ivy patterns have been defined for that resolver. It
is therefore possible to workaround the bug by adding the following element
within the Ibiblio resolver(s) that use snapshot versions.
{code:xml}
<ivy
pattern="[organisation]/[module]/[revision]/[artifact]-[revision](-[classifier]).[ext]"/>
{code}
The root of the problem is the following line of code:
{code:java}
String pattern = (String) getIvyPatterns().get(0);
{code}
I'd naively suggest the following as a fix to default the M2_PATTERN if none is
defined for the resolver as this will cause
org.apache.ivy.plugins.resolver.IBiblioResolver.shouldUseMavenMetadata(String)
to return true if the resolver is configured to use maven metadata and is M2
compatible since the default pattern would always end with the M2_PATTERN:
{code:java}
String pattern = (String) (getIvyPatterns().isEmpty() ? M2_PATTERN :
getIvyPatterns().get(0));
{code}

I don't know enough about when it would make sense to define an ivy pattern for
an Ibiblio resolver, but if the ivy pattern is not needed it would be simple
enough to just pass M2_PATTERN to the shouldUseMavenMetadata method:

> Components: Core
> Affects Versions: 2.0
> Reporter: Daniel Nielsen
> Assignee: Maarten Coene
> Fix For: 2.1.0-RC1

>
> I changed the java.net resolver to use the maven2 of download.java.net and
> added m2compatible and usepoms=true. Now it does not fail with NPE.
> --------------------
> I think you've found a bug in Ivy.
> It seems to be caused by your "java.net" resolver. Could you try what happens

> If that helps, could you please open a JIRA ticket?
