             Summary: Use of MojoRule causes Guice injection error
                 Key: MPLUGINTESTING-45
                 URL: https://jira.codehaus.org/browse/MPLUGINTESTING-45
             Project: Maven Plugin Testing
          Issue Type: Bug
            Reporter: Sam Corbett


I'm trying to write some tests for a plugin. I am using:
* Maven version 3.2.3
* maven-plugin-testing-harness version 3.2.0
* JUnit version 4.12

I'm following the instructions at 
http://maven.apache.org/plugin-testing/maven-plugin-testing-harness/getting-started/index.html
 that may or may not be out of date.

Any use of the {{MojoRule}} class causes all tests to fail with a Guice 
injection error.

For example, this useless class:
{code}
package io.brooklyn.maven;

import org.apache.maven.plugin.testing.MojoRule;
import org.junit.Rule;
import org.junit.Test;

public class FakeTest {

    @Rule
    public MojoRule mojoRule = new MojoRule() {
        @Override
        protected void after() {
            super.after();
        }

        @Override
        protected void before() throws Throwable {
            super.before();
        }
    };

    @Test
    public void testNothing() {
    }

}
{code}

fails with:

{code}
