Hi there! I've just started trying to make smth with processing and faced with this problem: java.lang.NullPointerException at processing.app.Library.getClassPath(Library.java:296) at processing.app.Library.<init>(Library.java:194) at processing.mode.java.JavaMode.getCoreLibrary(JavaMode.java:149) at processing.mode.java.JavaBuild.preprocess(JavaBuild.java:400) at processing.mode.java.JavaBuild.preprocess(JavaBuild.java:185) at processing.mode.java.JavaBuild.build(JavaBuild.java:144) at processing.mode.java.JavaBuild.build(JavaBuild.java:123) at processing.mode.java.JavaMode.handleRun(JavaMode.java:160) at processing.mode.java.JavaEditor$19.run(JavaEditor.java:473) at java.lang.Thread.run(Thread.java:680) What would be the possible reason for this? evaklish@gmail.com
