Two ways to pass command line arguments into mvn:exec:
Method 1, on the command line:
mvn exec:java -Dexec.mainClass="com.myPackage.myClass" -Dexec.args="command line arguments"
Method 2, in the maven POM file:
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<configuration>
<mainClass>com.myPackage.myClass</mainClass>
<commandlineArgs>command line arguments</commandlineArgs>
</configuration>
</plugin>
</plugins>
</build>
Then on the command line all you have to do is run:
mvn exec:java
Good luck.
