Eclipse RCP Platform Migration

Question

Is there any utility/tool that can help in migrating an existing Eclipse RCP 3.6 platform to Eclipse RCP 4.2 (Juno) platform. (I mean an RCP application running in 3.6 platform to 4.2).

Kindly point out if there are any existing guidelines/tips to carry out the same.

Also if there are any downside to migrating to 4.2 platform.

Answer 1

我认为这可能会有所帮助： 从Eclipse 3.x迁移到Eclipse 4（e4）

Answer 2

AFAIK没有这种工具，但是您可以在Lars Vogel的将Eclipse 3.x插件和RCP应用程序迁移到Eclipse 4教程中找到一些提示和准则。

Answer 3

I did some E3 to E4 migrations for work.

• This is a tool you can use: Eclipse 4 Migration Tooling: https://opcoach.github.io/E34MigrationTooling/ .

Some documentation on using the above tool is provided on the tool's website and in the website of this page https://www.eclipsecon.org/france2016/session/truth-about-migrating-eclipse-4 (get the pdf)

These are the most useful articles for migrating:

• http://www.vogella.com/tutorials/Eclipse4MigrationGuide/article.html

Remember, even if you just use the compatibility layer you could need to change some code, ie event management in the handlers.

Bottom line, there are no downsides in migrating to E4. E3 Standalone is not supported anymore, and E4 is a more recent technology, which allow to reduce the boilerplate code. The Eclipse IDE itself runs E3 components, on top of the E4 Compatibility Layer.

My sugggestion: migrate by steps: first use the compat layer. Then, if needed, start moving E4 components using the E4 paradigm.
