-----------------------------------------

             Summary: ClassDefNotFound exception
                 Key: MPLUGINTESTING-27
                 URL: https://jira.codehaus.org/browse/MPLUGINTESTING-27
             Project: Maven 2.x Plugin Testing
          Issue Type: Bug
          Components: plugin-testing-harness
    Affects Versions: 2.1
         Environment: Maven 3.0.4, JDK 1.7, MacOSx
            Reporter: Artur Keska


I'm trying to extend an existing project using p.-t.-hatness.
So I added to my project dependency:

 <dependency>
      <groupId>org.apache.maven.plugin-testing</groupId>
      <artifactId>maven-plugin-testing-harness</artifactId>
      <version>2.1</version>
      <scope>test</scope>
 </dependency>

And extended the test class follow the quick start guide.

On the first run I have following exception:

It loks like the Aether classes are not found. So I simply added dependency:

 <dependency>
      <groupId>com.rempl</groupId>
      <artifactId>rempl-cli</artifactId>
      <version>1.1.3</version>
      <classifier>bin</classifier>
      <scope>test</scope>
    </dependency>

And now I have exception:

Caused by: java.lang.ClassNotFoundException: org.apache.maven.execution.MavenExecutionRequest

That's funny because MavenExecutionRequest is a part of the Maven core and should be just available. Anyway I checked what's happend if I will add maven-core manually. When adding dependency:
   <dependency>
      <groupId>org.apache.maven</groupId>
      <artifactId>maven-core</artifactId>
      <version>${maven-version}</version>
      <scope>test</scope>
    </dependency>

I have another error:
Caused by: java.lang.ClassNotFoundException: org.apache.maven.execution.MavenExecutionResult

Hmmm... This is also a part of maven-core. This brings me to the conclusion, that trying to add dependencies manually was was a bad idea and there must be another solution.

I will appreciative for any idea what can I do.
