Run java jar - no main manifest attribute error

Ive created a simple java program (maven with pom), which, when I run some command with CMD, should create a file at the given path ... I do mvn clean install that end successfully, now I want to use this created jar from the command line, as shown below:

java -jar   "/Users/i012/IdeaProjects/myproj/target/test.rts-1.0-SNAPSHOT.jar" path2genfile2create

Why should my program run (this is the first time I try something like this ...)

But the error I get is:

no main manifest attribute, in /Users/i012/IdeaProjects/myproj/target/test.rts-1.0-SNAPSHOT.jar

What could be missing here? which exhibits the attribute ?

The error does not arise from the created class. ...

I created some META-INF / MANIFEST.MF without helping, but maybe wrong

Maven IDE, mainClass. , :

in my case, I used spring-boot, but I did not mention my creator in my pom, so I fixed it:

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>
