maven引入本地jar包的方法

发表于 2022-07-29 15:08:22 by 月小升

我用第二种办法搞定的，个人推荐第二种，成本低，见效快，适合多人开发

方法1：直接安装到本地库

mvn install:install-file -Dfile=D:\dechnicLib\INetSDK.jar -DgroupId=com.dahua.netsdk -DartifactId=dahua-netsdk-jni -Dversion=1.0.0 -Dpackaging=jar -DgeneratePom=true  -Dmaven.repo.local=E:\USERDATA\maven\repository

pom 里

<dependency>
    <groupId>com.dahua.netsdk</groupId>
    <artifactId>dahua-netsdk-jni</artifactId>
    <version>1.0.0</version>
</dependency>

这个模式有个弊端，如果要发布到服务器，必须在服务器的环境里也要操作一次mvn install，如果项目组有8个小伙伴，都要折腾一遍

方法2：引用本地文件

<dependency>
            <groupId>com.inspur.msy</groupId>
            <artifactId>green-channel-core</artifactId>
            <version>1.3.6</version>
            <scope>system</scope>
            <systemPath>${pom.basedir}/lib/green-core-1.3.6.jar</systemPath>
        </dependency>

${pom.basedir} pom.xml 文件所在的那个目录

部署的时候，告诉maven别忘记本地这个jar文件

<plugin>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-maven-plugin</artifactId>
	<configuration>
		<fork>true</fork><!--热部署devTools生效-->
        <includeSystemScope>true</includeSystemScope><!--包含 本地 引入jar包-->
	</configuration>
	<executions>
        <execution>
             <goals>
                 <goal>repackage</goal>
             </goals>
         </execution>
     </executions>
</plugin>

要点来了：

2022年7月22，我打包微信官方的wxpay的包，结果用mvn install微信支付sdk的工程项目项目可以跑
用jar包就不行，但是IDEA完全不报错，后来查了一下午发现了问题微信支付的sdk用mvn install的时候出现了一个文件wx-pay-sdk.pom 内容如下

他标明SDK有三个依赖，我们如果直接打包拷贝到工程里，那么就必须在自己的pom.xml里加上这三个依赖。就好了

<dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpclient</artifactId>
            <version>4.5.3</version>
        </dependency>
 
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
            <version>1.7.21</version>
        </dependency>
 
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-simple</artifactId>
            <version>1.7.21</version>
        </dependency>

方法3：创建一个新的本地 Maven仓库

第三个方案和第一个很像，不同点在于JAR包安装到另外一个本地maven仓库中。

假设本地仓库名称为：maven-repository。位于${basedir}目录.

先将本地JAR包发布到新的本地仓库中

mvn deploy:deploy-file -Dfile=<path-to-file> -DgroupId=<group-id> -DartifactId=<artifact-id> -Dversion=<version> -Dpackaging=jar

<repositories>
    <repository>
        <id>maven-repository</id>
        <url>file:///${project.basedir}/maven-repository</url>
    </repository>
</repositories>

方法4：用自己的远程仓库

最佳方式：使用Nexus仓库管理器
最好的方法是使用包含你自定义JAR包的Nexus仓库管理器，可将其用下载依赖的远程仓库。
这个可以单独开一篇了，不细聊
