Answer 1

我会建议VE（可视化编辑器）上安装一个新的eclipse3.5设置，用干净的空的工作区，以当然。
（或者至少移除“<workspace>/.metadata/.plugins”目录“org.eclipse.jem.beaninfo”等“org.eclipse.ve.java.core”。

下载all-in-one update site（zip文件），将它解压缩，然后引用它作为一个更新的网站，在“可用软件站点”首选项页面。
从那里安装应该能够顺利进行。

尝试下载安装&从Soyatec这个插件... http://www.soyatec.org/update/Ganymede/org.eclipse.ve_1.4.0.v20080528.zip
