Missing requirement: Atlassian Connector for Eclipse (recommended) 1.1.0.v20090624 (com.atlassian.connector.eclipse.feature.group 1.1.0.v20090624) requires 'org.eclipse.mylyn.jira_feature.feature.group [3.2.0.I20090529,3.3.0)' but it could not be found
Cause
This is most likely an error from P2 (Eclipse's update mechanism in Eclipse 3.4 and higher). The problem seems to be that the Mylyn update site is not enabled in your copy of Eclipse. There is a bug in Eclipse that these sites may not be automatically enabled even though we specify that we require them for installation.
If any of the installed features have unsatisfied dependencies or if features were previously installed from the extras or incubator update site, P2 may fail with an error similar to the one above.
Resolution
Follow these steps to enable the required sites:
- In Eclipse, open 'Help', 'Software Updates'.
- Click the 'Available Software' tab.
- Click 'Manage Sites'.
- Look for either the 'Mylyn Extras' update site or a URL that looks like this:
http://download.eclipse.org/tools/mylyn/update/extras
- Make sure that the site or URL is checked.
- Look for either the 'Mylyn For Eclipse 3.4' update site or a URL that looks like this:
http://download.eclipse.org/tools/mylyn/update/e3.4
- Make sure that the site or URL is checked.
- Now you should update all installed features to the latest version. Click the 'Installed Software' tab.
- Click 'Update'.
- Restart if prompted.
- Try to install the Atlassian Connector for Eclipse again.
