2. 检查run configuration

上一篇文章中我们启动Application是通过.product文件中的Launch Application来启动。在这里介绍另外一种通过run as的配置文件来启动Application.

为了检查和编辑我们的run configuration ,从Eclipse IDE的菜单中选择 Run–> Run configurations ….

 在Main选项卡中，Location 我们可以指定Eclipse 在运行时创建的一些必要的存储文件的位置。

3. Run Arguments

run configuration 允许我们在arguments中添加一些额外的信息。默认的情况下，Eclipse的这个选项卡下已经包含了一些信息。比如 -os, -ws, -arch 等等。

下表为一些常用的启动配置信息：

Parameter Description consoleLog Error messages of the running Eclipse application are written to standard-out (System.out) which can be viewed in the Eclipse IDE Console view that started the RCP application. nl Specifies the locale used for your application. The locale defines the language specific settings, i.e., which translation is used and the number, date and currency formatting. For example -nl en starts your application using the English language. This is useful for testing translations. console Provides access to an OSGi console where you can check the status of your application. noExit Keeps the OSGi console open even if the application crashes. This allows to analyze the application dependencies even if the application crashes during startup. clearPersistedState Deletes cached runtime changes of the Eclipse 4 application model.
