I was setting up to run graddle from my terminal using "grails dev run-app" command, then an error occurred.

I'm not sure what causing the error, but what I have installed are:

  • Java JDK 1.8.0_111
  • Grails 3.0.14
  • MySQL

I have tried to use "grails clean" and try to use "export=JAVA_HOME='/Library/Java/JavaVirtualMachines/jdk1.8.0_111.jdk/Contents/Home'" but still outputs the same error.

This is the simplified long error:

Running application... objc[3493]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.8.0_111.jdk/Contents/Home/bin/java and /Library/Java/JavaVirtualMachines/jdk1.8.0_111.jdk/Contents/Home/jre/lib/libinstrument.dylib. One of the two will be used. Which one is undefined.

  • What went wrong: Execution failed for task ':bootRun'.

Deeply thanks for anyone who could provide a solution to this matter.

You have no rights to access to the bbdd you have set on the application.yml file.

The warning message Running application... Which one is undefined is not matter. I think your failure cause by wrong password for 'mobileeyeclinic'@'localhost' or may be the MySQL is not running as a service. See this link Class JavaLaunchHelper is implemented in both. One of the two will be used. Which one is undefined for more info
