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
Priority: Minor
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
