How do I execute a program using Maven

Question

I would like to have a Maven goal trigger the execution of a java class  I m trying to migrate over a Makefile with the lines   neotest      mvn exec java -Dexec mainClass  org dhappy test NeoTraverse    And I would like mvn neotest to produce what make neotest does currently   Neither the exec plugin documentation nor the Maven Ant tasks pages had any sort of straightforward example   Currently  I m at    lt plugin gt     lt groupId gt org codehaus mojo lt  groupId gt     lt artifactId gt exec-maven-plugin lt  artifactId gt     lt version gt 1 1 lt  version gt     lt executions gt  lt execution gt       lt goals gt  lt goal gt java lt  goal gt  lt  goals gt     lt  execution gt  lt  executions gt     lt configuration gt       lt mainClass gt org dhappy test NeoTraverse lt  mainClass gt     lt  configuration gt   lt  plugin gt    I don t know how to trigger the plugin from the command line  though

In order to execute multiple programs  I also needed a profiles section   lt profiles gt     lt profile gt       lt id gt traverse lt  id gt       lt activation gt         lt property gt           lt name gt traverse lt  name gt         lt  property gt       lt  activation gt       lt build gt         lt plugins gt           lt plugin gt             lt groupId gt org codehaus mojo lt  groupId gt             lt artifactId gt exec-maven-plugin lt  artifactId gt             lt configuration gt               lt executable gt java lt  executable gt               lt arguments gt                 lt argument gt -classpath lt  argument gt                 lt argument gt org dhappy test NeoTraverse lt  argument gt               lt  arguments gt             lt  configuration gt           lt  plugin gt         lt  plugins gt       lt  build gt     lt  profile gt   lt  profiles gt   This is then executable as  mvn exec exec -Ptraverse

With the global configuration that you have defined for the exec-maven-plugin    lt plugin gt     lt groupId gt org codehaus mojo lt  groupId gt     lt artifactId gt exec-maven-plugin lt  artifactId gt     lt version gt 1 4 0 lt  version gt     lt configuration gt       lt mainClass gt org dhappy test NeoTraverse lt  mainClass gt     lt  configuration gt   lt  plugin gt    invoking mvn exec java on the command line will invoke the plugin which is configured to execute the class org dhappy test NeoTraverse   So  to trigger the plugin from the command line  just run   mvn exec java   Now  if you want to execute the exec java goal as part of your standard build  you ll need to bind the goal to a particular phase of the default lifecycle  To do this  declare the phase to which you want to bind the goal in the execution element    lt plugin gt     lt groupId gt org codehaus mojo lt  groupId gt     lt artifactId gt exec-maven-plugin lt  artifactId gt     lt version gt 1 4 lt  version gt     lt executions gt       lt execution gt         lt id gt my-execution lt  id gt         lt phase gt package lt  phase gt         lt goals gt           lt goal gt java lt  goal gt         lt  goals gt       lt  execution gt     lt  executions gt     lt configuration gt       lt mainClass gt org dhappy test NeoTraverse lt  mainClass gt     lt  configuration gt   lt  plugin gt    With this example  your class would be executed during the package phase  This is just an example  adapt it to suit your needs  Works also with plugin version 1 1
