This post has reported that the flex builder work on linux has been put on hold. Noted Adobe techie has said “there is not enough requisition for the product to continue its development”
Well, that’s not a great news to hear.. considering the open sourced SDK of adobe flex, good amount of interest was generated in the FOSS developer community. To help it revive again, use this link to vote on the adobe site.
From the current builder available on linux ,which is infact a eclipse plugin, the main feature I missed was, the design view in it. Hopefully, when the development continues design view is also ported to linux.
