There is no automated uninstaller.
You have to remove Eclipse manually by deleting some directories and files.
Note: I use Unix style paths in this answer but the locations should be the same on Windows or Unix systems, so
~ refers to the user home directory even on Windows.
Why is there no uninstaller?
According to this discussion about uninstalling Eclipse, the reasoning for not providing an uninstaller is that the Eclipse installer is supposed to just automate a few tasks that in the past had to be done manually (like downloading and extracting Eclipse and adding shortcuts), so they also can be undone manually. There is no entry in “Programs and Features” because the installer does not register anything in the system registry.
How to quickly uninstall Eclipse
Just delete the Eclipse directory and any desktop and start menu shortcuts and be done with it, if you don’t mind a few leftover files.
In my opinion this is generally enough and I would stop here, because multiple Eclipse installations can share some files and you don’t accidentally want to delete those shared files. You also keep all your projects.
How to completely uninstall Eclipse
If you really want to remove Eclipse without leaving any traces, you have to manually delete
- all desktop and start menu shortcuts
- the installation directory (e.g.
- the p2 bundle pool (which is often shared with other eclipse installations)
The installer has a “Bundle Pools” menu entry which lists the locations of all bundle pools. If you have other Eclipse installations on your system you can use the “Cleanup Agent” to clean up unused bundles. If you don’t have any other Eclipse installations you can delete the whole bundle pool directory instead (by default
If you want to completely remove the Eclipse installer too, delete the installer’s executable and the
Depending on what kind of work you did with Eclipse, there can be more directories that you may want to delete. If you used Maven, then
~/.m2/ contains the Maven cache and settings (shared with Maven CLI and other IDEs). If you develop Eclipse plugins, then there might be JUnit workspaces from test runs, next to you Eclipse workspace. Likewise other build tools and development environments used in Eclipse could have created similar directories.
How to delete all projects
If you want to delete your projects and workspace metadata, you have to delete your workspace(s). The default workspace location is ´~/workspace/´. You can also search for the
.metadata directory to get all Eclipse workspaces on your machine.
If you are working with Git projects, these are generally not saved in the workspace but in the
Addendum: Windows Registry
Even though Eclipse isn’t “installed” like a regular Windows application, there are still a few entries that get written to the system registry. If you search the Registry for “eclipse” you’ll likely find some entries for URL handlers named
eclipse+installer. They are used e.g. for letting you install Eclipse plugins from the browser.
On my system I see a few other entries which I believe are created by Windows itself and not by Eclipse (e.g. entries in the list of recently used executables). Whether you want to delete those entries is up to you. Personally I wouldn’t, but on the other hand it probably won’t break anything if you do. Just be aware that registry “cleaning” is a controversial topic.
