Description

Another report for MASSEMBLY-214, but I will try to be more specific.
The stack trace is the same (included below just for easy reference), but this is the project configuration:

• Grand parent project with a dependency management to junit:junit:4.4 with scope test.

• Grand parent project with plugin management configuring the assembly plugin:

  <plugin>
      <artifactId>maven-assembly-plugin</artifactId>
      <configuration>
          <descriptorSourceDirectory>src/assembly</descriptorSourceDirectory>
      </configuration>
      <executions>
          <execution>
              <id>make-assembly</id>
              <phase>package</phase>
              <goals>
                  <goal>attached</goal>
              </goals>
          </execution>
      </executions>
  </plugin>
  

• Project POM references the junit dependency and assembly plugin:

  <dependencies>
      <dependency>
          <groupId>junit</groupId>
          <artifactId>junit</artifactId>
          <version>4.4</version>
      </dependency>
  </dependencies>
  
  <build>
      <plugins>
          <plugin>
              <artifactId>maven-assembly-plugin</artifactId>
          </plugin>
      </plugins>
  </build>
  

By grand parent project I mean that the modules has a parent and the parent project also has a parent, but just the direct parent lists the project as module.
I "resolved" this by specifing the junit dependecy version for 4.4, but that is not quite right.
