转换为maven后出现错误：找不到或加载主类

Question

Suddenly I got an error when converting to maven. I create a simple java project, run main class, get results. After converting to maven - I got error : Could not find or load main class.

I tried deleting eclipse and its folder and download it again and get the same error. Do you know what can be the problem?

public class Main {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
            System.out.println("Hello World");
    }

}

What I have noticed is that when I covert the project to maven, the maven did not create 'Maven Managed Dependencies'. Moreover I click on configure build path --> Add library --> Maven Managed Dependencies . and it does not add the folder.

Answer 1

Try this:

Right click on the project > Properties > Maven > Java EE Integration > Uncheck the option "Maven Archiver generates files under the build directory".

This should fix it. If it doesn't try Maven clean and install again.
