• Type: Bug

• Environment: Java 1.8 Maven 3.3.9 (explicit dependencies on 3.3.9)

Description

When trying to use the maven-plugin-testing-harness per the instructions, any 3.3.x Maven version produces the following error:

java.lang.NoSuchMethodError: org.apache.maven.artifact.versioning.DefaultArtifactVersion.compareTo(Lorg/apache/maven/artifact/versioning/ArtifactVersion;)I
	at io.cotiviti.test.maven.MyMojoTest.setUp(MyMojoTest.java:36)

Specifically from this code in org.apache.maven.plugin.testing.AbstractMojoTestCase, line 149-150 :

        assertTrue( "Maven 3.2.4 or better is required",
                    MAVEN_VERSION == null || new DefaultArtifactVersion( "3.2.3" ).compareTo( MAVEN_VERSION ) < 0 );

During the run, MAVEN_VERSION is set to 3.3.9 (correctly). However, for whatever reason, the compareTo function of DefaultArtifactVersion does not seem to be available.
