maven如何打包?

1.先创建一个maven项目

  在main/java中建立一个cn包 包里面一个Har类

 

 

package cn;
public class Har {
     public static void main(String[] args) {
          System.out.println("你好");
     }
}

2.在pom.xml配置文件中进行添加依赖

添加依赖,成为执行包

配置代码

<build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>
                <version>3.3.0</version>
                <configuration>

                            <addClasspath>true</addClasspath>
                            <classpathPrefix>lib/</classpathPrefix>
                            <mainClass>cn.Har</mainClass>
                        </manifest>
                    </archive>
                </configuration>
            </plugin>
  </plugins>
</build>

打包运行

 查看打包文件

 

 

 

  

 

3.添加其他架包进行打包

配置代码中添加jsoup架包 

添加配置文件,,成为执行包

  second
        <plugin>
        <!--可将其他插件也加入打包，会生成lib目录-->
        <!-- maven-dependency-plugin -->
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-dependency-plugin</artifactId>
        <version>3.6.0</version>
        <executions>
            <execution>
                <id>copy-dependencies</id>
                <phase>package</phase>
                <goals>
                    <goal>copy-dependencies</goal>
                </goals>
                <configuration>
                    <outputDirectory>${project.build.directory}/lib</outputDirectory>
                </configuration>
            </execution>
        </executions>
        </plugin>-->

        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>


    <build>
    <plugins>
<!--   second-->
        <plugin>
        <!--可将其他插件也加入打包，会生成lib目录-->
        <!-- maven-dependency-plugin -->

        <artifactId>maven-dependency-plugin</artifactId>
        <version>3.6.0</version>
        <executions>
            <execution>
                <id>copy-dependencies</id>
                <phase>package</phase>
                <goals>
                    <goal>copy-dependencies</goal>
                </goals>
                <configuration>
                    <outputDirectory>${project.build.directory}/lib</outputDirectory>
                </configuration>
            </execution>
        </executions>
        </plugin>

</plugins>
 </build>

</project>

 

在Har类中输出获取百度的标题和你好

package cn;

public class Har {
     public static void main(String[] args) {
          try{

          System.out.println(Jsoup.connect("http://baidu.com").get().title());
                  }catch(Exception e){
                       e.printStackTrace();
                  }
          System.out.println("你好");
     }
}

然后进行打包

我们阔以看到当添加架包时会自动创建一个lib目录自动存放架包

进入控制面板查看结果

 

 

 

4.直接生成来两个JAR文件(添加架包)

在配置代码中进行一些代码的修改

                                        implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                                    <mainClass>cn.Har</mainClass>
                                </transformer>
                            </transformers>
                        </configuration>
                    </execution>
                </executions>

                    <!-- maven操作后执行cn.webrx.Main类 test install complie

                    <phase>package</phase>
                    <goals>
                        <goal>java</goal>
                    </goals>
                    <configuration>
                        <mainClass>cn.Har</mainClass>
                    </configuration>
                </execution>

                        <mainClass>cn.Har</mainClass>
                    </configuration>
                </execution>
            </executions>
        </plugin>

</plugins>
 </build>
</project>

 

在Har类中打印mysql的标题吧

package cn;
public class Har {
     public static void main(String[] args) {
          try{

          System.out.println(Jsoup.connect("http://MySql.com").get().title());
                  }catch(Exception e){
                       e.printStackTrace();
                  }
         
     }
}

 依旧是打包

阔以看到此次打包在控制台就会打印出mysql的标题

 

进入文件查看

控制台输出

 

程序到这完成
