NullPointerException from URLResolver (URLRepository

    Details

    • Type: Bug Bug
    • Status: Resolved
    • Priority: Minor Minor
    • Resolution: Fixed
    • Affects Version/s: 2.2.0
    • Fix Version/s: 2.3.0-RC1
    • Component/s: Core
    • Labels:
      None
    • Environment:

      Windows 7, Ant 1.8.1, Ivy 2.2.0, Java 1.6

      Description

      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
