when compiling and running processing script, I get the following error:
Exception in thread "main" java.lang.NullPointerException at processing.app.Sketch.<init>(Sketch.java:103) at processing.app.Commander.<init>(Commander.java:198) at processing.app.Commander.main(Commander.java:97)
Compilation exited abnormally with code 1 at Mon Jun 6 10:20:23
I found some pages on google with the same issue but there are old and don't seem to have been solved.
