From Maven, how do I run a class that lives under src/test/java?

Question

I have inherited a codebase :)

Under src/test/java/ there\'s a file that I need to run (I need to run its public static void main(String[] args), not a

(...) I hope this is clearly explained.

Not bad but I can't reproduce. I created a project:

$ mvn archetype:generate -DgroupId=com.stackoverflow \
                         -DartifactId=Q4060613 \
                         -Dversion=1.0-SNAPSHOT \
                         -DarchetypeArtifactId=maven-archetype-quickstart 

Then cded into it and created a Dog class (under src/main/java):

$ cd Q4060613
$ cat > src/main/java/com/stackoverflow/Dog.java
package com.stackoverflow;

public class Dog {
    public String bark() {
        return "woof!";
    }
}

and created a Demo class (under src/test/java):

$ cat > src/test/java/com/stackoverflow/Demo.java 
package com.stackoverflow;

public class Demo {
    public static void main(String[] args) {
        System.out.println(new Dog().bark());
    }
}

After compiling the source code, running the command you provided works as expected:

$ mvn test
...
$ mvn exec:java -Dexec.mainClass="com.stackoverflow.Demo" -Dexec.classpathScope="test"
[INFO] Scanning for projects...
...
[INFO] --- exec-maven-plugin:1.2:java (default-cli) @ Q4060613 ---
woof!
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
...

Something else must be wrong.
