Hi devs,
I use the maven-eclipse-plugin 2.9-SNAPSHOT to make a maven project to
eclipse plugin, I get the error info:
[INFO] Trace

The jira: http://jira.codehaus.org/browse/MECLIPSE-642 describe and it's
still open.
Then I check out the source code to find out what happens.
At last, I think the root cause is:
List resources = config.getProject().getResources();
if ( resources != null )
{
Iterator it = resources.iterator();
while ( it.hasNext() )
{
Resource resource = (Resource) it.next();
String relativePath = resource.getDirectory().substring( basedir.length()
).replace( '\\', '/' ); // Error happens here
coreSettings.put( PROP_JDT_CORE_COMPILER_ENCODING + relativePath, encoding
);
}
}
because the resource.getDirectory() is shorter than basedir!!!
I have a work-around way to resolve it, but I could not submite it directly,
so I attach the patch here. Please review and check it, If it works fine and
doesn't cause other regressions, please check it in, as my product will use
maven-eclipse-plugin frequently, thank you very much!
