我感到无以言表的沮丧。 我升级到STS 2.9.2，希望摆脱我在2.9.1中遇到的大量问题。 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，然后重新启动 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 - 我的所有项目都是为 grails 2.1.0 配置的?!?
我需要在哪里查找才能找到对圣杯 2.0.3 的流氓引用？
谢谢！
经过多次搜索，我发现了问题。错误是报告正在引用grails 2.0.3 jar，尽管当然，这不是任何活动项目中的设置首选项。我搜索了所有首选项和.project文件。什么也没找到。
然后我在 .metadata 中看到文件：

删除了所有启动文件，重新启动了 STS，瞧，它起作用了。 不再有关于缺少 2.0.3 jar 文件的运行时错误。
