grails - grails命令有错误

当我输入grails upgrade命令时，出现以下错误:

| Error Error occurred running Grails CLI: null (NOTE: Stack trace has been filtered. Use --verbose to see entire trace.)

java.lang.NullPointerException
at org.grails.cli.GrailsCli.initializeProfile(GrailsCli.groovy:516)
at org.grails.cli.GrailsCli.initializeApplication(GrailsCli.groovy:307)
at org.grails.cli.GrailsCli.execute(GrailsCli.groovy:270)
at org.grails.cli.GrailsCli.main(GrailsCli.groovy:159)
| Error Error occurred running Grails CLI: null

问题是什么？解决办法是什么？

最佳答案

我的项目是grails 1.3.9，我安装了grails 3.3.5

我在系统中安装了grails 1.3.9，没关系
