Note! BlueJ 4.0.0 involved a significant re-write of the user interface and internal interfaces of BlueJ. Many extensions below may not work correctly, or at all, with this and newer versions of BlueJ. In the long term the extensions API may need to be re-designed (see the relevant Jira issue) and extensions will then need to be updated to the newer API.
Installing extensions
Extensions are installed by placing the extension jar file into an extension directory. BlueJ has three separate locations for extensions, each giving the extension a different scope. The locations are:
| Location | Availability |
<BLUEJ_HOME>/lib/extensions (Unix), or <BLUEJ_HOME>libextensions (Windows), or <BLUEJ_HOME>/BlueJ.app/Contents/Resources/Java/extensions (Mac, Control-click BlueJ.app and choose Show Package Contents) | For all users of this system in all projects. |
<USER_HOME>/.bluej/extensions (Unix), or <USER_HOME>bluejextensions (Windows), or <USER_HOME>/Library/Preferences/org.bluej/extensions (Mac) | For a single user for all projects. |
<BLUEJ_PROJECT>/extensions | For this project only. |
Writing extensions
To find out how to write your own extensions, read the Guide to Writing Extensions for BlueJ. You will also need the BlueJ Extension API documentation. To share an extension you have written, mail iau@bluej.org (Ian Utting) and tell us about it!
