See the exec maven plugin  You can run Java classes using   mvn exec java -Dexec mainClass  com example Main   -Dexec args  argument1         The invocation can be as simple as mvn exec java if the plugin configuration is in your pom xml  The plugin site on Mojohaus has a more detailed example    lt project 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 version gt 1 2 1 lt  version gt                   lt configuration gt                       lt mainClass gt com example Main lt  mainClass gt                       lt arguments gt                           lt argument gt argument1 lt  argument gt                       lt  arguments gt                   lt  configuration gt               lt  plugin gt           lt  plugins gt       lt  build gt   lt  project gt

The above mentioned answers are correct but I am simplifying it for noobs like me Go to your project s pom file  Add a new property exec mainClass and give its value as the class which contains your main method  For me it was DriverClass in mainpkg  Change it as per your project     Having done this navigate to the folder that contains your project s pom xml and run this on the command prompt mvn exec java  This should call the main method
