Run-tasks causes exception (invalid directory) - why?

Hi guys

The run task returns with an exception I do not understand. This is the stacktrace:

* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':jComponent Library Sorcerer:run'.

In fact, I expect an exception refering the java module system and controlsfx library, but this was unexpected. Does anyone have an idea, why this occurs?

PS: Sorry, german windows system, “Der Verzeichnisname ist ung³ltig” means: The name of the directory is invalid.

PPS: You may take a try by yourself here: jCLS / git / [8b6669]
Or git clone https://git.code.sf.net/p/jcls/git jcls-git

A fresh clone of that project does not even compile.
But it is most probably because you configured build/dist as working directory of the run task while the directory does not exist.
