Eclipse莫名其妙打不开了？！

或许不是莫名奇妙，可能在装hadoop的时候重装了一下java,然后eclipse就打不开了。打开的时候报错：

n error has occurred. See the log file /home/solohermex/.eclipse/org.eclipse.platform_3.7.0_155965261/configuration/1337069840757.log.

然后我去找log文件，错误如下：

!SESSION 2012-05-15 16:25:54.852 -----------------------------------------------
eclipse.buildId=I20110613-1736

解决办法：

32位系统：ln -s /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86/
64位系统:ln -s /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86_64/
