Yes, it is possible. In fact, the Scala Eclipse plugin itself is written in Scala.

I've never created a Scala RCP app myself, but I'm guessing that what you need to do is create the project normally using your wizard of choice. Once the project is in your workspace, right-click and select "Add Scala Nature" (or something to that effect). The result will be a Scala project with all of the regular trappings of an RCP app. You should be able to use both Java and Scala within the project after these setup steps.

After adding Scala Nature to the plug-in project, don't forget to include scala.library among the dependencies of your plugin (and update the corresponding run and product configuration)! (Additionally, if another JRE system library appears in the build path when adding Scala Nature, you can safely remove it to avoid the RequiredExecutionEnvironment warning.)

blocks|key|22239|text|有没有人把它当做一个实际的出口产品？我很高兴地开发了我的scala插件，它在Eclipse中运行得很好，但是当我尝试导出产品时，构建过程失败了，因为它无法将我的scala对象解析为一个类型。我发现了这个bug报告：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|22240|http://lampsvn.epfl.ch/trac/scala/ticket/1919|offset|length|22241|entityMap|0|LINK|mutability|MUTABLE|url^0|0|0|19|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@$D|O|E|P|1|Q]]|A|$]]|$1|F|3|-4|5|6|7|R|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|C]]]]

Did anyone get it to work as an actual exported product? I was happily developing my scala plugin and it was running great inside Eclipse, but when I tried to export the product, the build process failed saying it couldn't resolve my scala object to a type. I found this bug report:

<a href="http://lampsvn.epfl.ch/trac/scala/ticket/1919" rel="nofollow noreferrer">http://lampsvn.epfl.ch/trac/scala/ticket/1919</a>

blocks|key|612179|text|用Scala编写的插件代码不能与RCP一起工作的原因很简单，那就是在构建插件jar时，.class文件不会被导出。但是您可以使用一个变通方法:使用插件Manifest+Editor打开plugin.xml，选择Runtime选项卡，并为类路径添加一个新条目"bin“。然后在Build选项卡上的二进制构建树中，选择bin文件夹。当您导出产品时，在工作区中编译的类文件将被导出到插件jar中。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|612180|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

The reason the plugin code written in Scala doesn't work with RCP is simply that the .class files don't get exported when the plugin jar is built.
But there is a workaround you can use: Open the plugin.xml with the Plug-In Manifest Editor, select the Runtime tab and add a new entry "bin" for the classpath. Then on the Build tab, in the Binary Build tree, select the bin folder.
The class files that are compiled in the workspace are then exported into the plug-in jar when you export the product.

The Scala Nature invokes the JDT compiler and makes the Java classes available tot he Scala compiler. I was having an issue where I have both the Scala Nature and Java Nature enabled. Make sure you don't have the Java Nature enabled.

This is an old question; but an update may be helpful to someone. 

I can say that I have successfully created a Scala RCP application using the scala 2.8.0 beta release. The improvements are notable. I followed the steps described <a href="http://lampsvn.epfl.ch/trac/scala/wiki/EclipsePluginsWithScala" rel="nofollow noreferrer">here</a>. It was easier than I initially thought. 

For good measure I then translated the Java code to Scala ... one file at a time.

I tried it out and it worked for me.

The Scala Eclipse plugin page says:
* Support for Eclipse plugin and OSGi development including hyperlinking to Scala source from plugin.xml and manifest files.

How does this support work? There's no wizards for making Scala plugins. I've found no documentation on how to use Scala in a Eclipse plugin/RCP application. Is it even possible?

Scala Eclipse插件页面上写道：*支持Eclipse插件和OSGi开发，包括从plugin.xml和清单文件到Scala源代码的超链接。这种支持是如何工作的？没有用于制作Scala插件的向导。我还没有找到关于如何在Eclipse插件/RCP应用程序中使用Scala的文档。这有可能吗？
