Use Eclipse 4.x as development environment for Eclipse 3.x rcp/plugin? [message #1705612]

My specific situation is I want to use the latest version of Groovy (as well as Java 8) for my RCP/Plugin application, and those don't appear to be available for Eclipse 3.x. However, due to constraints regarding supporting Eclipse 3.x (due to other vendors having stayed at that version) I have to develop a 3.x application, not a 4.x application.

Having said that, I can only get the two to run when using Eclipse 3.x as a development environment. If I copy and move the workspace over to 4.x the PDE plugin will try and launch things expecting a 4.x environment which appears to be giving me issues. Everything online seems to be tutorials migrating from 3.x to 4.x. I don't wish to migrate, I wish to use Eclipse 4 for dev, and compile against as well as run within Eclipse 3, so I can use all the latest tooling features for groovy and Java 8 yet still run against an older version of Eclipse. Is this even possible?

You need to set 3.x as the target platform

I looked that up and set it up with my Eclipse 3 installation and it worked. I'll switch it to something more generic so it isn't machine specific but the Target Platform is indeed the thing I needed to modify. Unfortunately, all google searches for running Eclipse 3 plugins/rcp apps from Eclipse 4 kept hitting migration tutorials so I had ended up going down the wrong path. Thanks for your help.
