Configuration sharing with Dropbox, Part 2: Eclipse
This article explains how you can easily share your Eclipse configuration between workspaces.
Since Eclipse’s preferences are always to a workspace, you need to reset all your preferences each time you start a new workspace, which can be a lot of work. Especially if you have a memory like mine. Therefore, sharing configurations is useful even without the added cloudiness of Dropbox. Maybe you have only one development machine anyway. However, it’s still worthwile storing your configuration in Dropbox, if only for the automagic backups it makes. So I recommend that you read Part 0 anyway.
- Create a folder called
~/Dropbox/config. That’s it.
Per Eclipse set-up
For each of your Eclipse installations, whether they be on different computers, or different versions of Eclipse on the same machine, you will need to do the following:
- Install the Workspace Mechanic plugin. You will see a green check box icon somewhere in Eclipse’s status bar.
- Record some settings!
- First, open up Window|Preferences, and press OK. This flushes any default settings that might otherwise get cluttered up into your shiny new shared preferences.
- Right-click the Workspace Mechanic icon in the status bar, pick Preference Recorder, and Start Recording.
- Open up Window|Preferences again and change a setting.
Alternatively, right clicking in various places often shows preferences that you can change. For example, clicking in the margin of any editor view will let you toggle “Show Line Numbers”.
- Press OK to close the Preferences again.
- Right-click the Workspace Mechanic icon and Stop Recording. You will get a popup window that will let you describe your new preference.
- Check that the list box only contains keys that are relevant to the change you just made. Otherwise, try to execute step 0 again.
- Fill in a name and a description.
- Browse to
~/Dropbox/config/eclipseand fill in a file name. The customary file extension for this kind of files is
- Save your setting.
I recommend that you repeat steps 2-8 for each individual preference you have, rather than lumping them all in one big preferences file. That makes it a lot easier to clean up unwanted preferences later on, and also to share them with your friends and co-workers.
Also, I recommend that you choose your names, descriptions and file names carefully. You will end up with lots of small preference files, and this way it will be a lot easier to identify them.
Per workspace set-up
- In Window|Preferences, find the Workspace Mechanic node.
- Under Task Sources, click the New button.
- Navigate to
~/Dropbox/config/eclipseand press OK.
- Press OK to close Window|Preferences, and you will see a small popup window
telling you that the Workspace Mechanic has found issues.
- Press View and correct configuration issues.
- You can now review all individual preferences. Or you can just press OK.
Your preferences are now loaded!
A cool feature of Workspace Mechanic, is that it will periodically scan your
preferences directory to see if new preferences have been added. So if a friend
sends you an
.epf file and you drop it into the preferences directory, you
will automatically get a notification!
Instead of having just one
config/eclipse folder, you can have several! For
example, if you often switch between Java and Scala development, like I do, you
can create the following folders:
config/eclipse/scala and only load the relevant to
the Workspace Mechanic. That way, I can have Ctrl+N create a new Java class in
a Java workspace, and a new Scala class in a Scala workspace.
