At the time of writing Flash Builder 4 doesn’t ship with the default plugin installers, which makes adding things like ANT a bit of a chore.

UPDATE: The latest RC for Flash Builder 4 now supports plugins again. I have updated the links to include the Eclipse plugin URL for each plugin.

This post is as much a reminder to me for future builds as it is for anyone else sick of having to manually look up where to down load the most common plugins every time they update. Start by downloading all the plug in files:


To get ANT installed you need to download and install JDT for eclipse.

Manual install:

Eclipse update URL:

Flex Formatter

Once you have used Flex Formatter you will never look back. It automatically formats your code, making you look like you have spent lots of time lining everything up. You can download the plugin files here

Eclipse update URL:


Subclipse is a must for anyone using SVN in their projects. It stops you running into a lot of problems, like turning up .svn files in search results. You can get it here

Eclipse update URL:

For the manual install, once you have downloaded and unzipped these files copy the content of their plugin folder to the plugin folder in your Flash Builder 4 directory. You may also want to copy the features folder content to the features folder in the Flash Builder 4 folder too.

Once done restart Flash Builder and everything should be working.

Also be sure to check out SourceMate (currently in Beta).

    Thank you so much for this post – it really helped me to get going with plugins for Flash Builder. I have an odd issue where Help>Software Updates… does not provide a sub-menu to ‘Find and Install’, so I have been trying to figure out how to get ANT installed manually. You got me half way there with the JDT download and the eclipse update URL, but what is the url/direction for ANT? Thank you!

    Chris, do you have admin rights on your user account? I know Adobe took a while to get it working so it respected restrictions.
