On a remote Windows 10 system *sbt* failes to start with a **NoClassDefFoundError**:

```

* Tried with different SBT versions (1.6.2, 1.5.8, 1.4.9) by changing *project/build.properties*): The Stack Trace differs depending on the version, but it is always a `NoClassDefFoundError`.
* The SBT version specified in the project is successfully downloaded by the launcher.

I suspect local file permission problems as cause (e.g. due to security policies) therefore i moved the boot and the coursier cache directory. However, this did not bring the desired success.

Does anyone have an idea what the Problem could be?
