Currently, classes defined in a script are not visible outside that script. And
so you can only use a task class within the script where it is defined. This is
something we want to fix.
A simple workaround is to set the task class as a project property in the
script:
project.Xslt = Xslt.class
class Xslt extends DefaultTask {... }
Then you should be able to do something like this in other scripts:
task transform(type: Xslt) { ... }
