As reported upstream

03 / ORIGINAL ISSUE TEXT

iluwatar/java-design-patterns #2565 · read the original issue

The project includes Maven Assembly plugin to produce executable jars out of all the submodules (individual patterns). However, there currently seems to be a problem with the intended behaviour. 

Steps to reproduce:

1. At the project root build everything, i.e. `mvn clean package -DskipTests=true`
2. Execute one of the produced jars, e.g. `java -jar spatial-partition/target/spatial-partition-1.26.0-SNAPSHOT.jar`

Expected behaviour

- The spatial partition jar is executed and the pattern example runs without problems

Actual behavior

- An error message `no main manifest attribute, in spatial-partition/target/spatial-partition-1.26.0-SNAPSHOT.jar` is printed
