Some time ago Adobe published a blog post
Running Adobe Flash Builder on Mac with Java 7 and 8
to fix a couple of issues with FlashBuilder on macOS
they updated this article with a new section
Flash Builder 4.7 crash on Mac OS 10.13 (High Sierra)
With the recent update of Mac OS 10.13 (High Sierra), “Flash Builder stopped working”
error is encountered when you click Project-> “Export Release Build”.
If you are facing this issue follow the steps below:
- Download the attached zip (fb.zip) which contains 2 jar files.
- Copy the 2 jar files and paste them at the location: “/Applications/Adobe Flash Builder 4.7/eclipse/plugins/”.
- Restart Flash Builder.
As a side note, if you build on the command-line you don't really have this problem .
