eclipse - Grails 3.2.9和Eclipse Luna 4.4.2

Question

我刚刚安装了Grails 3.2.9，这是grails -version的输出

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

试图从New Grails project制作Eclipse Luna 4.4.2，但发生此错误

 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.

任何导致这些错误的想法。

导致此错误的原因是Eclipse Luna不支持Grails3。您可以尝试升级到Mars或更高版本(最好是后来的版本)，或者像其他人建议的那样升级另一个IDE，但是不幸的是，Luna于2014年发布，而且过时了目前支持Grails 3。
