eclipse的WindowBuilder插件打开错误

Question

按照论坛上的正常步骤安装了windowBuilder插件后，在eclipse新建WindowBuilder
的时候，总是报错：

The selected wizard could not be started.
Plug-in org.eclipse.wb.rcp was unable to load class org.eclipse.wb.internal.rcp.wizards.project.NewProjectWizard.
An error occurred while automatically activating bundle org.eclipse.wb.core.java (590).

怎么解决啊？

Answer 1

新版本Eclipse会报错，可能是不兼容··
