从plug-in调用代码时出现问题:使用Checkstyle插件时为"org.eclipse.jface“

Question

我正在尝试使用Rational Software Architect 7.0.0.4上的eclipse-cs插件。

我最近卸载了较旧的beta2版本，并安装了beta3。插件本身的工作方式与之前的配置相同。但每当我试图通过Windows->Preferences->Checkstyle重新配置检查规则时，我得到以下错误：

从插件调用代码时出现问题："org.eclipse.jface“。

当我点击configure按钮并试图在UI上重新配置特定的选中检查规则时，就会出现这种情况。

以前有没有人遇到过这个问题?如何解决？

完整的错误列表和堆栈跟踪如下所示：

Answer 1

尝试使用-clean选项从控制台/终端启动Eclipse。

在Windows上：

Eclipse.exe -clean

在*nix上：

./eclipse -clean

或者如果Eclipse在您的路径中

eclipse -clean

这将清除您的插件缓存，也许它解决了这个问题。

Answer 2

我的简单猜测是，RSA 7.0所基于的Eclipse版本缺少您的check style版本所需要的一些方法。RSA 7.5使用的是Eclipse3.4，我对此非常满意。
