Installing CodeTogether Live in Eclipse

If you want to host a CodeTogether Live session from Eclipse, you’ll need to install the CodeTogether Live plugin for Eclipse. You can also join a session directly from Eclipse with the plugin installed.


The Eclipse plugin is not required to join sessions hosted from Eclipse. Participants can join from IntelliJ or VS Code with the corresponding plugin/extension installed, or from a browser with no additional installation required.

Installing the CodeTogether Live Plugin

CodeTogether Live requires Eclipse Neon (4.6) or higher to host a session, or Eclipse Photon (4.8) or higher to join a session from Eclipse. If you have the Marketplace Client installed, it’s simple to add CodeTogether Live to Eclipse. With Eclipse running, drag the Install button from our Eclipse Marketplace listing onto the workbench to initiate the installation. Alternatively, you can install the plugin using the button on the CodeTogether Live download page.

If you prefer using an Eclipse update site directly, use this URL:


When installing CodeTogether Live in older versions of Eclipse (prior to 2021.x), remove Latest Eclipse Release from the Available Software Sites list (Window > Preferences > Install/Update > Available Software Sites) prior to installation. This prevents Eclipse from installing incompatible third-party components that may lead to a broken installation state.

Getting Started

After adding the CodeTogether Live plugin to your Eclipse IDE, it’s simple to host or join a pair programming session. For more information, see the Getting Started Guide.


If you have a CodeTogether Teams plan, see Using CodeTogether Teams for details on how to host sessions and invite participants.
