Grails 3.0 错误，空指针 [英] Grails 3.0 error, nullpointer

问题描述

我只是试图通过grails"在命令行中运行 Grails 3.0.1，但由于以下堆栈跟踪而失败:

I was just trying to run Grails 3.0.1 in commandline via "grails" but it failed with the following stacktrace:

| Error Error occurred running Grails CLI: null
java.lang.NullPointerException
    at org.codehaus.groovy.runtime.DefaultGroovyMethods.collect(DefaultGroovyMethods.java:3137)

我正在使用这个版本的 Java

I'm using this version of 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)

推荐答案

我已经尝试了不同线程中提到的所有内容，包括设置 GRAILS_OPTS.运行后问题似乎消失了grails create-app myApp 并创建一个示例应用程序.

I have tried all the things mentioned in different threads, including setting GRAILS_OPTS. The issue seems to go away after running grails create-app myApp and create a sample app.

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

Not sure why, but seems like a connection problem with the Grails repo, which resolved after running the command.
