Grails 3.3.2 deployment to Jetty 9.1.4.v20140401

How do I build my Grails 3.3.2 app to deploy it into a Jetty 9.1.4 contained I provide (not embedded)?

I am trying to run my Grails 3.3.2 app in a Jetty (v 9.1.4) container. I added the following to my build.gradle file.

ext['jetty.version'] = '9.1.4.v20140401'

And tried several combinations of the Spring Boot container starter.

compile "org.springframework.boot:spring-boot-starter-actuator"
provided "org.springframework.boot:spring-boot-starter-tomcat"
compile "org.springframework.boot:spring-boot-starter-jetty"

but I continue to get errors.

I can run the app when embedding Jetty or Tomcat but not from my container.

I build the war from my project as follows.

 grails war
Solution

  • 2 things.

    1. You are missing jetty-jmx-<version>.jar dependency for that NoClassDefFoundError.

    2. Jetty 9.1.x is EOL (End of Life), consider upgrading. https://www.eclipse.org/jetty/documentation/current/what-jetty-version.html
