Although I have added the jar in the dependencies for both runtime and compiletime but still i am getting the same error.

Please help

Its important for my Project.

I Have tried the followings

  1. Adding the jars in the Runtime
dependencies {
       compile group:'javax.transaction', name: 'jta', version: '1.1'
            runtime group:'javax.transaction', name: 'jta', version: '1.1'
       }
  1. Setting classpath in the jettyRun
jettyRun{
  webAppSourceDirectory = file('WebContent')
    jettyEnvXml = file('./WebContent/WEB-INF/jetty-test-r4-offshore.xml')
    webDefaultXml=file('WebContent/WEB-INF/webdefault.xml')
   webXml=file('WebContent/WEB-INF/web.xml')
                additionalRuntimeJars+=file('jta-1.1.jar')
                       parentLoaderPriority='true'
                     classpath=files(file('jta-1.1.jar'))
    }
 }

but still I am facing the same error

Do you have a reproducible example build that you can upload somewhere so that we can give it a try? Please make it as small and simple as possible.
