    Which update site are you using? Make sure you’re using the Galileo update site

    Thank you for so useful article 😉

    Very helpful. I had to select “Other” after File > Import in order to find SVN.

    Thank you very much!

    This is all good and well, but Flash Builder constantly recreates the bin-debug folder for AS/Flex projects destroying the .svn folder inside. This makes the bin-debug folder impossible to version. Does Adobe have any plans on fixing this? It’s extremely frustrating.

    • Jason San Jose says:

      This is intentional. bin-debug should only contain derived files (compiled or otherwise copied from elsewhere) and is not intended to be versioned. You can right click on bin-debug, open properties, and uncheck the Derived property. This should allow Subclipse to pick it up for version control, but this is not typically recommended. Server projects are a different story if you have server-specific resources in your bin-debug folder.

    Running Flash Builder 4, Mac OS X 10.6.2

    I followed the instructions and have had to uninstall and install 3 times now. I keep getting the same error message when I try and connect to our company svn url.

    ***** error dialog message *****

    “Problem Occurred”
    An internal error occurred during: “Fetching children of [our_SVN_url]”.
    Unable to locate a login configuration

    ***** error dialog message *****

    I am still able to connect to the same svn url using Flex 3 with no issues.

    I had projects in Flash Builder already under version control, but Subclipse wasn’t recognizing them. I simply closed and opened the projects and that resolved the issue.

  9. Hi,

    I have a problem with committing ‘bin’ folder on Flash Builder Burrito. (ActionScript Project) Html Wrapper is not checked. I’m using flash player debugger. And i want to commit ‘bin’ folder. How does it work?


  10. Thanks! Very helpful instructions. Worked perfectly in my fresh install of FB 4 Premium 🙂

    Thanks! I installed it! 🙂

  12. Arne Bedürftig says:

    This does not work for me … SVN is not available for me after all.

  13. Sunny says:

    Great and easy.
    Thanks. It saved me a lot of time from resolving unnecessary dependencies.

  14. Scott says:

    Thanks for the tutorial, really helped. But the problem I have is Flash Builder now won’t do any of its code hinting. Do you know what the problem could be?
