的Aptana的RadRails与Eclipse> 3.5例外

Question

我一直在来回过的Eclipse版本，和其他IDE，我真的想用最新的Eclipse，酒店的套房我的口味。然而，每过一段时间，事情发疯，写入系统日志如下：

（我即将去尝试找到失踪的类，但我甚至不能确定的具体问题是什么。但我想我可能会尝试在这里）

Answer 1

我找到了这个问题的解决办法：摆脱异常，转到插件目录Eclipse安装和删除以下文件（或将它们移到一些安全的地方）：

com.aptana.editor.php_*.jar 
com.aptana.editor.php.epl_*.jar 
com.aptana.editor.php.formatter_*.jar 

当然，PHP编辑器不会是后可用，所以只能使用此解决方法，如果你不需要PHP的支持。

注意：删除php jars之前不要打开你的工作区！否则即使罐子被删除后，你也会得到例外。

由于我使用的Aptana Studio中只为Ruby开发，这为我工作于Eclipse E4 4.2。我仍在寻找更好的解决方案。
