David Ekholm created GROOVY-8221:
------------------------------------

             Summary: Not being able to refer to global variables via scripted methods
                 Key: GROOVY-8221
                 URL: https://issues.apache.org/jira/browse/GROOVY-8221
             Project: Groovy
          Issue Type: Bug
          Components: GroovyScriptEngine
    Affects Versions: 2.4.11
         Environment: Probably not relevant, but problem at least confirmed on Mac OS X
            Reporter: David Ekholm


We wish to switch from BeanShell to Groovy as script language (JSR-223) in our desktop software jAlbum. jAlbum injects a set of global variables into the scriptlets via the Bindings object of the JSR-223 API. These variables are directly accessible in simple scripts, but contrary to scripting in BeanShell, these variables are not available to methods declared within scripted classes.

Here's what works (assuming that "foo" is passed to the GroovyScriptEngine via the Bindings object):

println(foo) // foo being made available to the magically created Script class' run method

Here's what won't work (foo again being passed to the GroovyScriptEngine via the Bindings object):

class Test {
  void bar() {
    println(foo); // Reference to missing variable
  }
}

Test t = new Test()
t.bar() // Fails due to missing variable
