0 votes

I have the following problem. I would like to run mvn from command line for a file. accepts a parameter. How do I do that from command line?

I tried finding an example but I was not successful. Could someone help me by giving me an example of that?

How do I execute that command from a different folder than the folder?

For example the is located in my/java/program/ What should I put in

mvn exec:java -Dexec.mainClass="what to put here?" -Dexec.args="arg0 arg1 arg2"

Hello @kartik,

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 that is in a package test would need

mvn exec:java  -Dexec.mainClass=test.Main

By using the -f parameter, 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'"
