Adding a shell script e g  run sh makes it much more easier      usr bin env bash export JAVA PROGRAM ARGS  echo       mvn exec java -Dexec mainClass  test Main  -Dexec args   JAVA PROGRAM ARGS    Then you are able to execute     run sh arg1 arg2 arg3

You could run  mvn exec exec -Dexec args  arg1     This will pass the argument arg1 to your program   You should specify the main class fully qualified  for example  a Main java that is in a package test would need  mvn exec java  -Dexec mainClass test Main   By using the -f parameter  as decribed here  you can also run it from other directories   mvn exec java -Dexec mainClass test Main -f folder pom xm   For multiple arguments  simply separate them with a space as you would at the command line   mvn exec java -Dexec mainClass test Main -Dexec args  arg1 arg2 arg3    For arguments separated with a space  you can group using  argument separated with space   inside the quotation marks   mvn exec java -Dexec mainClass test Main -Dexec args   argument separated with space   another one
