    Description

      Having the following module hierarchy the unpack-dependencies goal of the maven-dependency-plugin produces an ArchiverException.

      • A
        • B
        • C (depends on B)

      I took a quick look into the code and found that when unpacking the dependencies of module C the method unpack(File, File, String, String) of class org.apache.maven.plugin.dependency.AbstractDependencyMojo gets passed the target/classes directory of B as source file (instead of the created jar).

      part of the pom.xml which caused the error:

      <profile>
  <id>multi-module-coverage</id>
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>

          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
</profile>

      exception:
