无法编译 Apache 教程中提供的我的第一个 Maven 项目
Could not compile my first Maven project as provided in the Apache tutorial
https://maven.apache.org/guides/getting-started/maven-in-five-minutes.html
这是我正在使用的教程,随后我成功创建了自己的应用嘿3
java版本:17.0.2
maven版本:3.8.5
但是下一步(“mvn package”)生成了以下“编译失败”
compilation error
这是系统默认生成的pom.xml:

报错中提到的App.java是这样的(在Sublime中打开):
package com.peter.2nd;
/**
* Hello world!
*
*/
public class App
{
public static void main( String[] args )
{
System.out.println( "Hello World!" );
}
}
上面提到的官方教程指出旧版本的 maven-compiler-plugin 可能存在问题,并提供了他们建议的 pom.xml 设置。我将这些设置复制到我的 pom.xml 中,但没有解决问题
不过现在我隐约意识到可能是编译器版本的问题。我在谷歌上搜索了一些解决方案,将这些设置复制到我的 pom.xml 中(抱歉,这是我作为新手所能做的全部)并且 none 有效
最新的 pom.xml 是我在阅读了一些有关配置的信息后所能做的最好的,但错误仍然存在

请帮帮我
问题是给定的包名称 package com.peter.2nd;
是不允许的,因为 2nd
是不允许的。
