Scala Eclipse Autocomplete Broken?

Question

I'm trying to get autocomplete working in eclipse for scala development. I'm trying to reference a java class from a Scala class, and the autocomplete feature never finds it.

for example take this scala class:

object Main {
 def main(args: Array[String]) {
  val btn = new JButton
 }
}

When I hit ctrl+space at the end of typing JButton autocomplete finds "Arr", "asof", "case", "catch", "def" etc... but no classes.

in Window->Preferences->Java->Editor->Content Assist->Advanced I have selected under "Default Proposal Kinds":

Java Proposals, Java Type Proposals, SWT Template Proposals and Template Proposals.

I'm using the Scala 2.8.0-final plugin under Eclipse 3.5.2, in Windows 7

Has anyone else encountered this problem? Any solutions?

Answer 1

That type of auto-completion is not yet supported by the Scala plug-in. You can get a similar result by waiting for the compile error to appear, pressing Ctrl-1, and selecting the quick fix to automatically import the type.

See the "Quick fix imports" section in this "New and noteworthy" post.

Update September 2011:

Luc Bourlier has committed an improvement for this to give autocompletion for types on the classpath. It will be in the next beta (2.0.0-beta11), or grab a nightly build.
