Your stacktrace doesn't show the real failure reason.

I suppose <putLibraryJarsInTempDir>true</putLibraryJarsInTempDir> might not help here, since there are not JARs. But it might help bring the length under the critical length.

Another thing you need to check is that your base path isn't outrageously long. If it is, try to shorten it, even though it isn't a full solution to this.
