Could not find or load main class Foo

Question

I have an Maven project with only this class:

This is <build><plugin> from pom.xml:

And this is tree of project:

I build this project with goal assembly:single and run it with command java -jar name.jar

The result is this error

I don't understand what is wrong.

Answer 1

Please call instead:

mvn clean package

It will generate required single jar with the org.raul.teste.Tester inside.

Calling assembly:single will generate META-INF\MANIFEST.MF only in your case, if you will open/unzip the result jar file in this case you will see that compiled classes were not included.
