Today I had a similar problem to the one in this post – but instead of hanging, Flash Builder just failed to start up and quit during the “loading workbench” phase of initialization.
In the earlier post, I mentioned deleting a .snap file in [workspacelocation]/.metadata/.plugins/org.eclipse.core.resources, but previously I hadn’t been able to find it. This time, there WAS a .snap file in that folder, but it was hidden.
Deleted it, and Flash Builder starts up like a champ.
According to this thread, Flash Builder will only notice when your library SWC changes if it’s in your project folder. Kind of sucks if you use the same SWC in multiple projects, like I do, but it appears to be the only option. Also, sometimes you need to clean the project to make the refresh happen.
Now, I’m not using the Flex framework, but also from the linked thread, if you use Flex you might be able to turn off a “global SWC cache.” I tried it for my plain-jane actionscript projects and it didn’t work.
Here’s the secondary method:
Find the .options file in the /Applications/Adobe Flash Builder 4.7/eclipse/plugins/com.adobe.flexbuilder.project_4.7.0.349722/ folder and look for a line like this:
# use a global swc cache across all projects when compiling with flex sdk 4 or higher com.adobe.flexbuilder.project/useGlobalSwcCache=true
Try setting useGlobalSwcCache to false then restart Flash Builder and see if that helps.
NOTE: This may result in longer compile times in Flash Builder if your workspace includes Flash Library Projects since those generated SWCs will no longer be cached and instead will be rebuilt every time.
Again, I tried this secondary option, but it didn’t work for me (OSX 10.10.3 Yosemite), possibly because I don’t actually use Flex, and the comment in the config file specifically mentions Flex SDK.
I use FlashDevelop for a lot of work projects. It’s a much better IDE for writing code-based ActionScript 3 projects than Flash itself.
Today, out of the blue, it started freezing on startup while trying to load the last project I had open. I thought I’d post about it in case a.) it ever happens to me again, or b.) it helps you, dear reader.
A quick Google search produced this forum thread, which solved it for me.
The solution was to rename/delete the file C:\Users\[USERNAME]\AppData\Local\FlashDevelop\Data\ProjectManager\Settings.fdb, which probably got corrupted.
Back to work! 🙂
