Description

All my Groovy classes don't compile anymore. It says:
"... cannot be resolved to a type"

Some errors I have seen:

  • Semikolons are required
  • parethesis are required when calling methods
  • method names including spaces are not supported

Even when removing the Groovy nature from the project it still tries to compile the Groovy files, resulting in the above errors.

Looks like it uses the Java compiler to compile Groovy classes.

I first have seen it in 2.1.2.xx-20110117-1900-e36 (but it could also be an ealier version). It's still there in 2.1.2.xx-20110118-1300-e36.

There is another strange thing. I removed the current Groovy Eclipse plugin version and reverted to an older one.

In "About Eclipse" -> "Installation Details" it shows the older version.
Under the "About Eclipse" -> "Groovy" button it shows the newer version.

After uninstalling the Groovy Eclipse plugin completely the "Groovy" button in "About Details" was still visible but in "Installation Details" the plugin is gone. Something screwed up Eclipse completely. So I started with a fresh Eclipse and the plugin seems to work even with the latest development version.

Is there a workaround for this bug since I'm experiencing the same problem. Latest eclipse with both 2.1.0 and 2.1.1 groovy eclipse plugin seem to suffer from this bug.

I think it's some upgrade bug between two special versions. As I stated in my last post, starting with a fresh Eclipse solved the problem. Or try to uninstall the Groovy Eclipse plugin completely before installation. Also check and clean all artefacts of the plugin from Eclipse's plugin folder.

I've seen this before. I think there was a problem with installation. I think this is related to:

http://jira.codehaus.org/browse/GRECLIPSE-953

It appears to be a p2 error (Eclipse's provisioning system). The only work around that I know of is to uninstall Groovy-Eclipse and reinistall it again.

I experienced this issue over the weekend when upgrading Eclipse (Java EE flavor) from Helios SR1 to Helios SR2 via the "Check for Updates" option. No other updates were applied during that update. After upgrading, all groovy files that didn't use exact java-compatible syntax reported errors.

Further testing:

Wondering if the issue was the upgrade, I removed my full eclipse install and downloaded and installed Eclipse Helios SR2 (eclipse-jee-helios-SR2-win32.zip), and installed Groovy plugin via "Install New Software" (using URL http://dist.springsource.org/release/GRECLIPSE/e3.6/) and got the same errors. All groovy files that didn't use exact java-compatible syntax reported errors.

Finally, I remove Helios SR2 and reinstalled Helios SR1, reinstalled Groovy plugin as above and everything worked again.

So from what I am seeing there is an incompatibility between Helios SR2 and the current Groovy plugin (2.1.1.xx-20101215-2100-e36).

You are correct. Groovy-Eclipse 2.1.1 is not compatible with SR2. Please install the nightly build of Groovy-Eclipse. Since we are gearing up for 2.1.2, the nightly build is quite stable and is unlikely to change much between now and the release.

The reason for this problem has to do with the versioning of the plugins. We ship a patch for the JDT core plugin that overrides the existing plugin. The version number that we override is only the version for SR1. So, SR2 is deemed to be "newer" than the version that 2.1.1 provides and thus overwrites it. The latest nightly fixes this problem.

I think that we figured out all of the problems happening here, so I am closing this issue.
