Suppose I have Maven Eclipse project. It has some classes with main, which I can run from Eclipse.
Now how can I run the same class from the command line?
The command
java -cp target/classes mypackage.MyClass
does not work, because it can't find jar files, download by maven.
The command
mvn exec:java -Dexec.mainClass="mypackage.MyClass"
also does not work due to uncomprehesive Maven errors.
How to accomplish?
UPDATE
mvn printout:
>mvn exec:java -Dexec.mainClass="tests.Runner01"
