Question

我刚刚在Eclipse Juno中安装了Jboss工具（Juno）插件，安装后我重新启动以获取更改，但从那时起它就没有打开IDE。它在日志文件中存储了以下错误。

java.lang.RuntimeException: Application "org.eclipse.ui.ide.workbench" could not be found in the registry.

请帮帮我。

Answer 1

Eclipse应用程序在插件中提供。 “org.eclipse.ui.ide.workbench”应用程序是Eclipse IDE的入口点，它与java或C程序中的main方法相当。 Eclipse IDE在插件“org.eclipse.ui.ide.application”中有它的应用程序，即主程序入口点。这个插件在插件xml中声明了IDE应用程序：

<extension id="org.eclipse.ui.ide.workbench" point="org.eclipse.core.runtime.applications">
    <application>
        <run class="org.eclipse.ui.internal.ide.application.IDEApplication"></run>
    </application>
</extension>

您的消息报告无法找到此应用程序。有很多可能的原因。 Eclipse插件声明依赖项，Eclipse是依赖插件的大图。无效的插件导致其他插件，这需要这个特定的无效插件，也会变得无效。这很可能发生在你身上。由于某种原因，您的安装行为错误，并以某种奇怪的方式删除，杀死或无效您的插件图。因此Eclipse应用程序没有暴露，因此Eclipse拒绝启动。

解决这个问题通常非常繁琐，你必须找出哪个插件被破坏并损坏了整个IDE。更简单的方法是简单地使用全新安装（使用全新的下载并在顶部安装插件）。

尝试使用-clean启动eclipse。如果这没有帮助，您还可以从工作区中删除.metadata。我会创建它的备份，以确保这将删除您的自定义设置。
