从 unix 命令行运行 jar 文件

Question

I have created a jar file from mvn command but when i am trying to run it i am getting below error:

java -cp target/new-repl.jar package.repl
Error: Could not find or load main class package.repl
Caused by: java.lang.ClassNotFoundException: package.repl

I got many links on stack overflow but none of them helped me. Could you please help me to run this from command line. Below is the my.java file:

package repl;

public class Test {

    public static void main(String[] args) throws IOException {
        ....
    }
}

POM.xml:

You can do like this. Type fully qualified class name instead of typing package name

java -cp target/new-repl.jar repl.Test

The error says it all

Error: Could not find or load main class package.repl

your class name is not package.repl, it is repl.Test
