Grails application error on startup

Question

I have a Grails app, but when I start it I get the following Exception.

ERROR --- [main] o.s.boot.SpringApplication: Application startup failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'grailsApplicationPostProcessor' defined in Dito.DocumentEngine.Application: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [grails.boot.config.GrailsApplicationPostProcessor]: Factory method 'grailsApplicationPostProcessor' threw exception; nested exception is org.grails.core.exceptions.GrailsConfigurationException: XML parsing error loading core plugins: Premature end of file.

There are similar question but none seem to work as those are not the same problem.

Below this error I get the next exception

Execution failed for task ':bootRun'. 
Process 'command '/usr/lib/jvm/java-8-openjdk-amd64/bin/java'' finished with non-zero exit value 1 

I am running the application from a Docker container.

Thanks for any help I can get.

Answer 1

Not sure why but I was missing a /gradle directory in my app's root folder. Apparently it was deleted with something I did.

Copied it from another project we had and that solved the issue.
