When I try to install the eclipse plugin for GAE I get an error:
Cannot complete the install because one or more required items could not be found. Software being installed: Google App Engine Java SDK 1.6.4 1.6.4.v201203300216r37 (com.google.appengine.eclipse.sdkbundle.e37.feature.feature.group 1.6.4.v201203300216r37)
I'm using the http://dl.google.com/eclipse/plugin/3.7 update URL, which is the latest I could find. Has anyone solved this issue?
Thanks in advance!
回答1:
Use this : http://dl.google.com/eclipse/plugin/4.2 as an update site
Source: http://code.google.com/p/google-plugin-for-eclipse/issues/detail?id=71#makechanges
回答2:
For me the problem was forgetting to start eclipse as administrator.
回答3:
If the issue is that we don't yet support 4.2, answer is to have patience. Eclipse plugins are complex beasts, and 4.2 is fairly new.

How to Install GWT Plugin for Eclipse on 3.8 or Juno:
1. Download zipped update site for 3.7
from http://code.google.com/eclipse/docs/install-from-zip.html
2. Unzip content.jar; rm content.jar
3. Edit content.xml; change
<required namespace='org.eclipse.equinox.p2.iu'
name='org.eclipse.platform.feature.group' range='[3.7.0,3.8.0)'/>
to
<required namespace='org.eclipse.equinox.p2.iu'
name='org.eclipse.platform.feature.group' range='3.7.0'/>
4. jar cMf content.jar content.xml (zip won't work)
5. Install from local update site
Please note that some features of the plugin might not work as they should (for example when running in debugging mode my Eclipse Juno crashed a couple of times).

It turns out that the antivirus (for some unknown reason) blocks the reading of xml file. Solution: PAUSE PROTECTION during installation.

I fixed this issue by click Help -> Check for updates, after that I installed this plug in and work as expected.
