Starting Eclipse
Here are some error messages or situations you may have encountered, with
suggested workarounds or solutions.
- An error has occured. See the log file H:\.eclipse_ws\.metadata\.log
You may find a variety of errors in that log file. It is possible that something corrupted
the configurations and information in the .metadata directory,
or an older version of some plugin is no longer compatible with the current version.
Here is a possible workaround:
- Open a command shell -- click on Start, then Run, and enter:
cmd
- Change to the .eclipse_ws directory
cd /d H:\.eclipse_ws
- Rename the .metadata directory
move .metadata .metadata.old
- Start Eclipse
You won't see your old projects any more, but they are still in
H:\.eclipse_ws. Using the Eclipse File menu, import the
projects into Eclipse.
- End Eclipse when finished.
This will save your configuration changes to the .metadata folder.
New Version of Eclipse and/or Its Plugins
Each summer, SET lab staff upgrade all applications to their latest versions. Eclipse
and its plugins are often
updated to new versions, and that means that some of the old projects in your Eclipse
workspace (by default, H:\.eclipse_ws may no longer work due to changes in metadata
and plugins.
The best thing to do in the case of new version problems is to:
- Start Eclipse
- Save your preferences
- Choose menu item: File/Export.../General/Preferences
- Click Next.
- Make sure "Export All" is checked.
- Provide a file name in "To preference file" field; suggestion: H:\eclipse_prefs
- Click on Finish.
- Close Eclipse.
- Rename your workspace to another name:
For example, in a command shell:
move H:\.eclipse_ws H:\.eclipse_ws.old
That will force Eclipse to create a new H:\.eclipse_ws workspace the next time it
is started.
- Start Eclipse
Don't be alarmed -- none of your preferences or projects will be there... yet.
- Restore your preferences.
- Choose menu item: File/Import.../General/Preferences
- Click Next.
- Provide the saved preference's file name in "From preference file" field (e.g., H:\eclipse_prefs.epf)
- Make sure "Import All" is checked.
- Click on Finish.
- Import your projects
- Choose menu item: File/Import.../General/Existing Projects into Workspace
- Click Next.
- Browse to your old workspace (e.g., H:\eclipse_ws.old)
- After the projects appear, click on Finish
You might have to close the Welcome tab to see them.
- Now you should be able to use all of the new or changed features with less problems.
