我可以通过运行 testng.xml 文件在 eclipse 中运行 TestNg 项目。构建 Maven 项目后，我尝试使用命令 java -jar jarname 在终端中运行 jar 文件。 但它显示错误“没有主要清单属性”。所以我创建了一个 runner 类并尝试通过 run as -> Java application 来运行该类。但它抛出错误“在类路径中找不到类” 我的代码如下。

runner.java

package runner;

import java.util.ArrayList;
import java.util.List;
import org.testng.TestNG;

public class TestNGrunner {

public static void main(String[] args) {
    TestNG runner=new TestNG();
     
    // Create a list of String 
    List<String> suitefiles=new ArrayList<String>();
     
    // Add xml file which you have to execute
    suitefiles.add(".//testng.xml");
     
    // now set xml file for execution
    runner.setTestSuites(suitefiles);
     
    // finally execute the runner using run method
    runner.run();

 }
}

那么我如何使用 Jar 文件运行这个 TestNG 项目。有人可以帮我吗？
