Maven returns error from mvn assembly:assembly

[Zaknarfen]

I am posting this issue to notify that even after a clean clone from the repository i am getting:

$ mvn -T 1C -q assembly:assembly -Dmaven.test.skip=true
[debug] execute contextualize
[debug] execute contextualize
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:2.4:assembly (default-cli) on project pignlproc: Error reading assemblies: No assembly descriptors found. -> [Help 1]

Solutions i found:

Solution 1)

Using only mvn package as mentioned in [1] instead of the mvn assembly:assembly. This works but states a warning.

Solution 2)

Modify the pom.xml to move the "descriptor" block out of the "execution" block as mentioned in [2] and run the assembly command with mvn -T 1C -q assembly:single -Dmaven.test.skip=true. This solution has no warnings. You need to do both changes or it won't work.
