我沮丧得说不出话来。我升级到 STS 2.9.2，希望摆脱我在 2.9.1 中遇到的过多问题。现在看来问题更严重了。
除了 jline_.dll 问题，它不断抬起丑陋的头（我找到的唯一解决方案是退出 STS，删除 .ivy-cache 并重新启动 STS），现在我什至无法运行我的任何项目，由于一些关于找不到 groovy-all-1.8.6.jar 的奇怪错误。
The archive: C:/springsource/**grails-2.0.3**/lib/org.codehaus.groovy/groovy-all/jars/groovy-all-1.8.6.jar which is referenced by the classpath, does not exist.
但是 - 我所有的项目都是为 grails 2.1.0 配置的！？！？
我需要在哪里找到这个对 grails 2.0.3 的恶意引用？
谢谢你！
经过大量搜索，我发现了问题。错误报告正在引用 grails 2.0.3 jar，当然，这不是任何活动项目中的设置偏好。我搜索了所有首选项和 .project 文件。没有找到任何东西。
然后我在 .metadata 中看到了文件：

我关闭了 STS，删除了所有启动文件，重新启动了 STS，瞧，它工作了。没有更多关于 2.0.3 jar 文件丢失的运行时错误。
