Error on Grails run-command

Question

I tried to create a command following the Grails docs:

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

But when I execute grails run-command my-example I get the following error:

: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.

The Application class was generated normally when I created the app and hasn't been modified.

The complete stacktrace is as follows:

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

Answer 1

Found my way here after the same problem in Grails 4, but running a command from a Grails 3 plugin. Then stumbled on to this line of code:

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

Adding my fully qualified application class name to the end of my command allows the script to execute. For example:

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

However, the script appears to continue to run after my command has executed successfully, and the build ultimately fails. I don't see this documented anywhere, and I'm not sure what's going on. Maybe it's because the command is in a plugin? Either way, wanted to provide a workaround in case anyone else hits this same issue.

Answer 2

Check this link https://github.com/grails/grails-core/issues/10501. Sorry I cant comment(not eligible) that's why posting as an answer.

Answer 3

My guess is that your command is returning false, which is supposed to cause the build to fail.
