Question

我刚安装Grails 3.2.9这里是grails -version

的输出

 Grails Version: 3.2.9
 Groovy Version: 2.4.10
 JVM Version: 1.8.0_131

尝试从New Grails project发出Eclipse Luna 4.4.2，但发生了此错误

 Command terminated with an exception: 
org.grails.ide.eclipse.longrunning.client.GrailsProcessDiedException: Grails 
process died (see details for partial output)
Grails process died
------System.out:-----------

------System.err:-----------
Error: Could not find or load main class 
org.codehaus.groovy.grails.cli.support.GrailsStarter

当我尝试从命令行运行create-app时出现以下错误：

     grails> create-app testme --stacktrace
| Warning Unrecognized flag: stacktrace.

导致这些错误的任何想法。

Answer 1

导致此错误的原因是Eclipse Luna不支持Grails 3.您可以尝试升级到Mars或更高版本（稍后是首选），或其他IDE建议的其他IDE，但遗憾的是Luna于2014年发布，现在已经太老了，无法支持Grails 3。

Grails 3.2.9和Eclipse Luna 4.4.2
