在构建中运行mvn checkstyle时构建成功

Question

我正在将mvn checkstyle作为构建的一部分运行，并已在pom.xml中配置了插件，以使构建失败。 但是，当我运行mvn clean install命令时，构建会成功。 这是pom.xml文件：

                </reportSet>
            </reportSets>
        </plugin>
    </plugins>
</reporting>

在pom.xml中添加报告部分之后，我运行了mvn site命令，然后在构建中添加了checkstyle插件后，我运行了mvn clean install。但是构建成功了。没有创建checkstyle.xml，没有创建checkstyle-suppressions.xml。这是Java代码。

package com.demo.test.quickstart;

/**
 * Hello world!
 *
 */
public class App 
{
public static void main( String[] args )
{
    System.out.println( "Hello World!" );
}

public static int getNumber10(){
    return 10;
}
}

有人可以帮助我吗？
