Upgrading Existing Eclipse Features

Upgrading from previous Eclipse IDE package to Neon (4.6) is NOT supported NOTE: Due to structural changes you cannot update from a Mars (or prior) all-in-one package to a Neon version. If interested in the technical details, see bug 332989 and bug 490515.. So to use Eclipse Neon IDE, you have to download a new package or use the Eclipse IDE Installer from . After Neon, the usual upgrade process detailed below works.

If upgrading the platform itself to the next full release (for example, from 4.2 to 4.3), except in the case of Mars (4.5) to Neon (4.6) - see above

  1. You first need to add the new release's repository as follows:
    1. Window > Preferences > Install/Update > Available Software Sites
    2. Click 'Add'
    3. Enter the URL of the new repository (for example, for Mars (4.5))
    4. Click 'Ok'
  2. Help > Check for Updates
  3. If updates are found, proceed through the install wizard and click Finish at the end.
  4. If upgrading the platform itself, when you are prompted to restart it is strongly recommended to do so. A restart may not be required when updating other features, but always select to restart if you are unsure.
  5. Check your Available Software Sites for release-specific update sites that may need updating as well, e.g. The Eclipse Project Updates URL changes with each release (typically release-specific sites hold the SDK/Source features and off-cycle hot fixes and are not required)

If you're using Ganymede (3.4): To upgrade installed software, do the following:

  1. Help > Software Updates...
  2. Switch to the 'Installed Software' pane
  3. Select one or more installed items to be upgraded. If nothing is selected, it will search for updates to all installed software
  4. Select 'Update', and proceed through the wizard if updates are found

If you're using Europa (3.3) and below: Run the Update Manager, using Help > Software Updates > Find and Install... > Search for updates of the currently installed features. The Update Manager will visit the Update site(s) for all your installed features/plugins and offer updates if any exist. However, in Eclipse 3.3 or earlier, it is NOT possible to upgrade the Eclipse platform itself, only its features. So, you could for example upgrade the CVS feature or the PDE feature from 3.2.0 to 3.2.1, but not eclipse.exe itself.

Fresh install

Occasionally you won't be able to upgrade Eclipse or certain features due to incompatible changes in the update technology. In these cases you will need to download a fresh install. Download a new build from the Eclipse download Web site ( and unzip it in a new directory. We strongly recommend against unzipping over your existing Eclipse version as unexpected side effects may occur, including (but not limited to): nausea, vomitting, shortness of breath, corrupt installation.

Complete upgrade instructions are always included in the Eclipse readme_eclipse.html file included with every build in the readme directory.

Windows specifics

Upgrades may require administrator privileges to succeed and may fail with error messages claiming "Only one of the following can be installed:" otherwise. Start Eclipse with "Run as administrator...".

Upgrading Other Features

Upgrading other features (like CDT, PDT, WTP...) can be done without the need to download a new platform binary, but because many projects align very closely (eg., the Eclipse 3.2 / Callisto or Eclipse 3.3 / Europa release trains) you will likely need to upgrade the Eclipse platform as well.
