Description

The following code:

import groovy.transform.Field

@Field List awe = [1, 2, 3]
def awesum() { awe.sum() }
assert awesum() == 6

leads to error in the editor: 'Groovy:Error: annotation @Field can only be used within a Script body.'. When creating Groovy Class, I marked 'Create Script' checkbox.

I am not seeing the editor problem that you are. I am running on the latest dev snapshot where things may have changed a bit. However, in the editor an in the inferencing engine, the @Field transform has not been applied. Currently, this is by design since there are many transforms out there that are not well behaved (such as @Lazy). Applying them in the editor will break editing functionality. We are considering a way to selectively run some transforms in the editor. See GRECLIPSE-1179.

That being said, is the compiler problem that you are seeing only appearing in the editor or do you see it in the problems view as well?

Compiler problem appears in both: in the editor (error marker) and in the Problems view. Previously I haven't bothered to run this script but now I see it works when started with Run As Groovy Script.

It will be possible to get this working by enabling a few flags internally to ensure AST transforms are run during reconcile and then to add this transform to your project build settings. I added a 2.8.0 resolve version to see if we should enable this by default.

So, if you manually edit your project's .settings/org.eclipse.jdt.core.prefs file and add a line like this:

org.eclipse.jdt.core.compiler.groovy.groovyTransformsToRunOnReconcile=org.codehaus.groovy.transform.FieldASTTransformation

You will get it to work. But, only after I make a change in Groovy-Eclipse to respect that setting.
