An Eclipse e4 RCP application that uses GEF 5 to create and manipulate shapes.

e4gef5shapes

An Eclipse e4 RCP application that uses GEF 5 to create and manipulate shapes. This project is a proof of concept to show how to accomplish a pure Eclipse e4 RCP application using GEF 5.x. I hope to also get the tycho headless RCP build working as well.

** This project has been updated for Eclipse 2020-12 **

What is working

• Eclipse e4 RCP product is launching a window
• Compiler errors and warnings are all resolved.
• Eclipse IDE is able to resolve all packages, plugins, features, etc.

What is NOT working

• At launch, there is some issue with javafx and this error is shown in the console:

Getting Started

After checking out the code, instruct Eclipse to import the projects. There should be 11 (nested) projects altogether.

Open the shapes.rcp.target file and click the "Set As Active Target Platform" link in the upper right corner.

Next, open the products/e4gef5shapes.product/e4gef5shapes.product product configuration file.

In the "Testing" section, click the "Launch an Eclipse application" link to launch the application.

Currently stuck!

At this point, the application window opens and is blank. The console window shows the following error output:
