<p>第一次下载 eclipse-jee-juno-SR2-win32解压开就报这个错误，害我换了几个jdk,真是郁闷。第一反应就是开日志(1)，然后把相应的关键字放到google里面去搜索。结果并没有什么有价值的东西。倒是更换关键字以后，改成eclipse打不开，但是给我提供了一些思路。</p>
<p>其中有一个方法是 在<span style="font-size:10px">"开始"-->"运行"---->打入"cmd"进入命令提示行后,再进入eclipse的安装目录,</span><span style="font-size:10px"> 然后输入eclipse -clean即可。</span></p>
<p><span style="font-size:10px">但这个方法并没有给我带来很大的希望，后来我就把E:\eclipse-java-juno-SR2-win32\eclipse\configuration下的除了config.ini以外的文件都删除了。虽然报错的显示跟截图一样，但日志的内内容变了。如日志(2)。</span></p>
<p><span style="font-size:10px">于是搜索继续，在其中一篇文章中我看到要替换E:\eclipse-java-juno-SR2-win32\eclipse\configuration\org.eclipse.equinox.simpleconfigurator\bundles.info这个文件里的内容，但我一打开就傻眼了，这么多都要替换成实际安装路径？那这个eclipse也太不智能了。于是我把这个<span style="font-size:10px">configuration目录下的这个目录和config.ini文件保留。</span></span></p>
<p><span style="font-size:10px"><span style="font-size:10px">然后再在eclipse.ini里加入红色字体。</span></span></p>
