--------------------------------
Resolution: Fixed

Was fixed in 3.1.0 (see @mcculls comment)
> @parameter using 'property' to allow custom naming convention, throws a NPE
> if the parameter is defined, but empty.

> Key: MNG-5097
> URL: https://jira.codehaus.org/browse/MNG-5097
> Project: Maven 2 & 3
> Issue Type: Bug
> Components: Plugin API
> Affects Versions: 3.0.3
> Environment: Gentoo Linux, amd64, multicore.
> Reporter: rydnr
> Priority: Minor
> Fix For: 3.1.0
>
> Attachments: build.log, empty-string-npe.zip
>
>
> The test case (not JUnit) is attached.
> If a Maven plugin runs within Maven 3.0.3, and defines
> /**
> * @parameter property="abc"
> */
> private String somethingDifferentThanAbc;
> public void setAbc(String value) {
> somethingDifferentThanAbc = value;
> }
> Works for non-empty values:
> <abc>abc-value</abc>
> But throws a NPE in
> org.codehaus.plexus.component.configurator.converters.ComponentValueSetter:331
>
> (fieldTypeConverter is null) with empty values:
> <abc></abc>
> It works in Maven 2.x. It works if you declare the
> property with no naming conventions:
> private String abc;
> As a side note, the plexus classes being used are not the ones declared in
> the pom, but the ones bundled within
> $MAVEN_HOME/lib/sisu-inject-plexus-2.1.1.jar.
> I couldn't find sisu-inject-plexus-2.1.1-sources.jar anywhere, but the
> repository itself is fortunately available at
> https://github.com/sonatype/sisu.git
> And then within
> /sisu-inject/containers/guice-plexus/guice-plexus-shim/src/main/java/
> I could have try to post a patch, but I'm not really sure about why this
> corner case is producing plexus-container's misbehavior.
