Maven: How to run a .java file from command line passing arguments
arguments, java, maven
Solution
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'"
Problem
I have the following problem. I would like to run `mvn` from command line for a `Main.java` file. `Main.java` 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? I looked here but didn't quite understand what I should do. Also, how do I execute that command from a different folder than the Main.java folder? for example the `Main.java` is located in `my/java/program/Main.java`. What should I put in ``` mvn exec:java -Dexec.mainClass="what to put here?" -Dexec.args="arg0 arg1 arg2" ```
