Grails 3 (Gradle) dependency without parent directory

Question

Can I not use the following Gradle approach to dependencies in Grails? I do not have nor want a parent directory; https://stackoverflow.com/a/19303545/2288004

When I try it, I get the the following error;

Caused by: java.lang.IllegalStateException: Expected method not found: java.lang.NoSuchMethodException: org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedContext.addApplicationListener(org.apache.catalina.deploy.ApplicationListener)

It works when I use a parent directory for the settings.gradle, but unfortunately it’s not how I want to structure the project.

Answer 1

The following was indeed the solution I was looking for,

include ":myplugin"
project(':myplugin').projectDir = new File(settingsDir, '../myplugin')

The error was down to how I was managing my tomcat dependencies between the two projects.

Tomcat was already being pulled in via the plugin but while I still needed to reference tomcat at compile time in the application, I also needed to make sure it was the same version, and so added the following just above "dependencies" to target the version I required;

ext['tomcat.version'] = '7.0.70'
