Error occurs while installing Groovy IDE in Eclipse

I am using Eclipse 3.7.0, and trying to install Groovy: I used this Link: Groovy

While installing by following instructions from that link, I got an error like this.

Error Message:

    Cannot complete the install because one or more required items could not be found.
    Software being installed: Groovy-Eclipse Feature 2.0.0开发者_开发问答.xx-20091027-1400-e34 (org.codehaus.groovy.eclipse.feature.feature.group 2.0.0.xx-20091027-1400-e34)

How can I fix this problem?

As of today, I don't believe there's a release build of the Groovy Eclipse plug-in for Eclipse 3.7. However, I've been using the dev builds of the plug-in for many versions and it's been extremely stable, so I'd recommend trying the dev build. The appropriate update site for 3.7 would be http://dist.codehaus.org/groovy/distributions/greclipse/snapshot/e3.7/
