我正在使用
Eclipse：Neon.1a版本（4.6.1）
Grails：版本2.3.11
Java：Version＆＃34; 1.8.0_101＆＃34;
我正在尝试使用导入向导将已经退出的Grails项目导入Eclipse工作区，我看到以下错误。
发生了错误。有关详细信息，请参阅错误日志 。org.springsource.ide.eclipse.commons.livexp.ui.GroupSection（Lorg / SpringSource的/ IDE /蚀/公地/ livexp / UI / WizardPageWithSections; Ljava /郎/字符串; [Lorg / SpringSource的/ IDE /蚀/公地/ livexp / UI / WizardPageSection;）V
如果我尝试强制导入Grails项目，那么我会遇到一个nullpointer异常。 （下面给出的堆栈跟踪）
