Open markjfisher opened 8 years ago

markjfisher commented 8 years ago

JDK: 1.8.0_92 Gradle: 2.14 OS: Linux groovyfx/groovy version:

compile 'org.codehaus.groovy:groovy-all:2.4.6'
compile 'org.groovyfx:groovyfx:8.0.0'

When i try to run the CanvasDemo, I get the following:

3 Other demos I've tried so far (only just started on groovyfx) are working, i.e. Accordian, Animation and HelloWorld.

Same problem with SpirographDemo. 10/12 demos working so far.
