I'm trying to write a maven plugin. I've added
maven-plugin-testing-harness to my project as a test dependency, and
created a very simple test that right now just tries to load a pom
whose only content is a <plugin> section to load the plugin.
If I have it load like this:
> <plugin> <groupId>org.opennms.maven.plugins</groupId>
> <artifactId>features-maven-plugin</artifactId>
> <version>1.0-SNAPSHOT</version> </plugin>
...it bombs with this exception:
org.apache.maven.plugin.testing.ConfigurationException: Cannot find a
configuration element for a plugin with an artifactId of
features-maven-plugin.
at
org.apache.maven.plugin.testing.AbstractMojoTestCase.extractPluginConfiguration(AbstractMojoTestCase.java:466)
I thought the "configuration" section of a plugin was supposed to be
optional. However, if I add "<configuration></configuration>" after
the <version> tag above, it gives me a new error:
org.codehaus.plexus.component.repository.exception.ComponentLookupException:
java.util.NoSuchElementException
role: org.apache.maven.plugin.Mojo
roleHint:
org.opennms.maven.plugins:features-maven-plugin:1.0-SNAPSHOT:generate-features-xml
at
org.codehaus.plexus.DefaultPlexusContainer.lookup(DefaultPlexusContainer.java:257)
...am I doing something wrong? Seems like the test framework is
breaking on the simplest things, I'm not sure how to start out if I
can't even unit test this.
Code is here:

Test is at:
