Question

我有基于Luna版本的RCP应用程序。迁移到Luna 4.4.2后，我发现以下错误

!ENTRY org.eclipse.e4.ui.workbench 4 0 2015-08-27 16:59:58.081

Root cause is 
    java.lang.ClassNotFoundException: org.eclipse.ui.internal.ide.application.addons.ModelCleanupAddon cannot be found by org.eclipse.ui.ide.application_

1.0.501.v20141111-1238.

我还应该向Luna Release添加什么？或者可能是我有配置错误？在64位平台上观察到此问题。 RCP应用程序是基于xtext 2.8.4的DSL实现

提前谢谢你亚历山大

Eclipse bugzilla中有一个类似的错误报告：https://bugs.eclipse.org/bugs/show_bug.cgi?id=423923

评论表明

您的工作区正在尝试加载org.eclipse.e4.ui.workbench.addons.splitteraddon.SplitterAddon.如果
，就会发生这种情况
1）从4.3.x目标启动时，您的工作区中有来自master的o.e.ui.workbench或

2）如果您使用4.3.x打开现有的Luna工作区

使用旧版本创建的工作区启动时，我遇到了类似的异常。在我的情况下，工作区是使用4.4创建的，并且在该工作区上启动基于4.5的应用程序时发生异常。

RCP应用程序找不到ModelCleanupAddon类
