Question

I have Flash Builder 4.6 installed and I’m trying to install the Eclipse Marketplace Client. It gives me update locations for Indigo and Helios. Which Eclipse is Flash Builder 4.6 built on?

Answer 1

Flash Builder 4.6 runs on Eclipse Indigo, but still supports Helios as a plug-in.

Eclipse Platform
Version: 3.7.0.v20110530-9gF7UHNFFt4cwE-pkZDJ7oz-mj4OSEIlu9SEv0f
Build id: I20110613-1736

Flash Builder 4.6 release notes state:

Flash Builder 4.6 supports installation as a plugin to an existing
Eclipse instance

PC: (Note: Your copy of Eclipse must be version 3.6/3.6.1/3.6.2/3.7,
32-bit and must contain a folder named “dropins”)

Mac: (Note: Your copy of Eclipse must be version 3.6/3.6.1/3.6.2/3.7,
32-bit, Cocoa, containing a folder named “dropins”).

Flash Builder 4.6 updated to Eclipse 3.7, per the What’s new in Flash Builder 4.6

When you install Flash Builder 4.6, you’ll notice that an updated
version of Eclipse 3.7 is included. However, Flash Builder 4.6 still
supports Eclipse 3.6 as a plug-in in case you aren’t ready to upgrade.
