Grails 3.0错误,nullpointer

Question

我只是试图通过"grails"在命令行中运行Grails 3.0.1但是它失败了以下的stacktrace:

| Error Error occurred running Grails CLI: null
java.lang.NullPointerException
    at org.codehaus.groovy.runtime.DefaultGroovyMethods.collect(DefaultGroovyMethods.java:3137)
    at org.grails.cli.profile.git.GitProfileRepository.getAllProfiles(GitProfileRepository.groovy:72)

    at org.grails.cli.GrailsCli.main(GrailsCli.groovy:99)
| Error Error occurred running Grails CLI: null

我正在使用这个版本的Java

java version "1.8.0_40"
Java(TM) SE Runtime Environment (build 1.8.0_40-b26)
Java HotSpot(TM) 64-Bit Server VM (build 25.40-b25, mixed mode)

Answer 1

我已经尝试了不同线程中提到的所有内容,包括设置GRAILS_OPTS.在运行grails create-app myApp并创建示例应用程序后,问题似乎消失 了.

不知道为什么,但似乎是Grails repo的连接问题,它在运行命令后解决了.
