项目打jar包的各种方法

项目使用jar

maven项目pom.xml 依赖也可以添加

 <dependency>     <groupId>cn.webrxgroupId>     <artifactId>utilsartifactId>
    <version>1.0version>
    <scope>systemscope>
    <systemPath>C:/Users/Administrator/Desktop/jar/utils.jarsystemPath>
dependency>

（3）jar打可以执行的程序包

App.java

package cn.webrx;
public class App { 
       
	public static void main(String[] args){ 
       
	    System.out.println("Hello World");
	}
}

C:\Users\Administrator\Desktop\jar>javac -d . *.java
C:\Users\Administrator\Desktop\jar>java cn.webrx.App
Hello World
C:\Users\Administrator\Desktop\jar>jar -cvfe app.jar cn.webrx.App cn
已添加清单
正在添加: cn/(输入 = 0) (输出 = 0)(存储了 0%)
正在添加: cn/webrx/(输入 = 0) (输出 = 0)(存储了 0%)
正在添加: cn/webrx/App.class(输入 = 420) (输出 = 295)(压缩了 29%)

C:\Users\Administrator\Desktop\jar>java -jar app.jar
Hello World

(4) idea开发工具发行项目jar

(5) maven 打jar

打可执行的jar 在maven 执行package并打包，并执行就可以了

project>

jdeps --list-deps 00dict.jar

-- 生成jre
jlink.exe --module-path D:\jdk\jdk-17.0.1\jmods --add-modules java.base,java.desktop --output jre

dict.bat内容如下
echo off
start /b ./jre/bin/javaw.exe -jar 00dict.jar

-- 设置直接打开jar文件，
（1）右键打开方式，选择jdk\bin\javaw.exe 

 (2) 运行中输出regedit 注册表
 找到如下配置，添加一个-jar
进入HKEY_CLASSES_ROOT\Applications\javaw.exe\shell\open\command，
修改默认的键值为 "D:\Program Files\Java\jre\bin\javaw.exe" -jar "%1" 。
