Sven Zethelius commented on IVY-1340:
-------------------------------------
Verified in 2.2.1.alpha_20120324002314. file: works now with no
NullPointerException.
> NullPointerException from URLResolver (URLRepository
> ----------------------------------------------------
>
> Key: IVY-1340
> URL: https://issues.apache.org/jira/browse/IVY-1340
> Project: Ivy
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.2.0
> Environment: Windows 7, Ant 1.8.1, Ivy 2.2.0, Java 1.6
> Reporter: Sven Zethelius
> Assignee: Maarten Coene
> Priority: Minor
> Fix For: trunk
>
>
> There is an inconsistency in the handling of URLResource "file:" URLs. If
> the url is "file:d:mydir/", it will discover the artifacts at that address,
> but the output contains a NullPointerException warning due to
> URLRepository.list(String) line: 119 (in 2.2.0). Changing it to
> "file://d:mydir/" gets rid of the NullPointerException. This is because of
> new URI(parent).getPath() returns null for file: but not file://. new
> URL(parent).getFile() works with both as an alternative.
> Also repros with 2.2.1.alpha_20120313100444
