我已经安装了我自己的Checkstyle更新网站插件，它已经安装得很好，但是当我重新启动Eclipse，我检查Window -> Preferences中的Checkstyle选项时，它出现了下一个错误:
无法创建选定的首选项页。自动激活bundle net.sf.eclipsecs.ui(854)时发生错误。
错误日志如下:

这个错误出现在Helios和Indigo中，但在Juno中不会，并且插件和特性版本是相同的。
我有什么问题?请帮帮我
亲切的问候
该插件显式地依赖于Eclipse4类，这些类仅在Eclipse4中可用。Eclipse的x流。当checkstyle的UI插件被创建时，你可以在堆栈跟踪中看到它:
Caused by: java.lang.NoClassDefFoundError: org/eclipse/e4/ui/model/application/MApplicationElement at net.sf.eclipsecs.ui.CheckstyleUIPlugin.(CheckstyleUIPlugin.java:242)
如果你确实需要旧版本的Eclipse插件，请使用Eclipse的更新管理器安装它，不要手动复制插件jar文件。更新管理器应该能够检测出哪个版本的插件与您的Eclipse版本匹配。
但我的建议是使用Eclipse Kepler，因为这是目前修复错误最多的最新版本。
