[KnisterPeter]

It would be great if you could recheck with the latest nightly build of smaller.

[whjvenyl]

I just rechecked with a sample project:
Version 0.8.0 completes successfully whereas 0.8.8 or the latest repository snapshot 0.8.9 do not work anymore (regardless of the environment it get's executed / win - unix)

The error message is always the one described above (de.matrixweb.vfs.VFSException: Failed to create valid URL).

So the standalone plugin seems to be broken as of now.

[KnisterPeter]

I'll have an open pull request regarding VFS where this error is thrown. Since a Java Update on Mac it doesn't work anymore in the current state. I'll investigate that and will patch it then.
On Linux this issue doesn't seem to be visible tho.

[KnisterPeter]

Hopefully with the VFS fix this issue is fixed also.
I'll recheck if the builds are done.
