Java 任何更改后，Eclipse都不会启动

我正在使用EclipseKepler开发一些java程序，今天早上我遇到了一个新问题：eclipse无法启动。直到昨天，一切都很顺利，但今天早上当我尝试执行它时，我发现

日志文件包含以下愚蠢的异常：

我试着跟随一些像线一样的东西

没什么可做的，我怎么解决这个问题呢？

Eclipse自己的罐子里有些东西看起来不对劲， 该错误表示从一个jar加载类失败， 尝试获取JAR的新副本，并在Eclipse目录中替换它

如果这不起作用，您最好安装一个新的eclipse副本（我建议您安装eclipse Luna）

尝试使用eclipse-inst-win64.exe安装它。这解决了我的问题：

---

这是在您选择工作区之前还是之后发生的？（如果您有一个默认工作区，您可能无法获得此选项）。@Magnilex这会在工作区选择之前发生。您是否尝试过运行

eclipse-clean-refresh

？如果这样做没有帮助，那么从另一个工作区开始（运行

eclipse-data

），看看这是否是安装或工作区的问题。如果是安装的话，试着重新安装（开普勒已经发布了两个版本，可能还是值得一试的）？您最近是否更改了JDK或JRE？@TimBiegeleisen否我没有更改任何java版本，我使用的是jdk1.7.0\u 60您可以尝试重新安装Eclipse，看看这是否解决了问题。这可能是返回开发的最快途径。我建议您安装EclipseLuna。为什么不使用最新版本的Eclipse Mars呢？我没有使用Mars的经验，可能会更好，但我根据自己的经验提出了建议，谢谢你的留言。
