我一直在Eclipse和其他IDE的版本上来回走动，我真的想使用最新的Eclipse，它符合我的口味。然而，每隔一段时间，事情就会发生变化，写入以下系统日志：
（我即将去尝试寻找失踪的班级，但我甚至不确定具体问题是什么。我想我可以尝试一下）

答案 0 :(得分：0)
我找到了解决此问题的方法：要摆脱异常，请转到eclipse安装中的plugins目录并删除以下文件（或将它们移动到安全的地方）：
com.aptana.editor.php_*.jar
com.aptana.editor.php.epl_*.jar
com.aptana.editor.php.formatter_*.jar
当然，php编辑器在此之后将无法使用，因此如果您不需要php支持，请仅使用此解决方法。
注意：在删除php jars之前不要打开你的工作区！否则，即使在删除了罐子后你也会得到例外。
由于我仅将Aptana Studio用于Ruby开发，因此Eclipse e4 4.2对我有用。我仍在寻找更好的解决方案。
