Failing with :cssToBin

When I run your plugin, it fails with

Execution failed for task ':cssToBin'.
> com.sun.javafx.tools.packager.CreateBSSParams

However, If I open netbeans and hit run ( It calls gradle run) it works fine.

Any idea what could cause this?

I ran into this issue too, and it appears that gradle isn't pulling in the ant-javax.jar dependency correctly. When I pull it in manually with the following line, I no longer get the error.

classpath files("${System.properties['java.home']}/../lib/ant-javafx.jar")

I have the same issue.

But the classpath-line (I thinkg, it should be under dependencies in javafx.plugin?) didn't work for me..

the problem is solved now. openJDK was used instead of oracles JDK.. pretty dumb mistake ;)
