Hi,
I'm running into problems building my projects using maven 2.0.9. The
error message returned by Maven, java.lang.AbstractMethodError:
org/apache/maven/wagon/StreamWagon.openConnection()V. Has anyone
encountered this error before? How do I fix this problem? I've provided
the screenshots and my settings.xml. Thanks.
Maven and Java versions:
Maven version: 2.0.9
Java version: 1.5.0
OS name: "linux" version: "2.6.9-67.0.20.elsmp" arch: "x86" Family: "unix"

Snippet from error output:
These will use the artifact files already in the core ClassRealm instead,
to allow them to be included in PluginDescriptor.getArtifacts().
