Grails 运行命令出错

Question

我尝试按照 Grails 文档创建命令：

https://docs.grails.org/latest/ref/Command%20Line/create-command.html

但是当我执行grails run-command my-example 时出现以下错误：

:compileJava NO-SOURCE
:compileGroovy UP-TO-DATE
:buildProperties UP-TO-DATE
:processResources UP-TO-DATE
:classes UP-TO-DATE
:findMainClass
:runCommand
Application class not found
:runCommand FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':runCommand'.
> Process 'command '/home/user/.sdkman/candidates/java/8u144zulu/bin/java'' finished with non-zero exit value 1

* Try:
Run with --info or --debug option to get more log output.

Application类是我创建应用时正常生成的，没有被修改过。

完整的stacktrace如下：

* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':runCommand'.

grails 和 groovy 版本是：

| Grails Version: 3.3.1
| Groovy Version: 2.4.11
| JVM Version: 1.8.0_144

Answer 1

在 Grails 4 中遇到同样的问题后在这里找到了我的方式，但是从 Grails 3 插件运行命令。然后偶然发现了这行代码：

https://github.com/joansmith3/grails-core/blob/master/grails-console/src/main/groovy/grails/ui/command/GrailsApplicationContextCommandRunner.groovy#L91

将我的完全限定的应用程序类名称添加到我的命令末尾允许脚本执行。例如：

./grailsw run-command my-command arg1 arg2 com.myapp.Application

但是，在我的命令成功执行后，脚本似乎继续运行，并且构建最终失败。我在任何地方都没有看到这个记录，我不确定发生了什么。也许是因为命令在插件中？无论哪种方式，都希望提供一种解决方法，以防其他人遇到同样的问题。

Answer 2

我的猜测是您的命令正在返回 false，这应该会导致构建失败。

Answer 3

查看此链接https://github.com/grails/grails-core/issues/10501。抱歉，我无法发表评论（不符合条件），这就是为什么发布作为答案。
