Maven常用命令

将jar安装到本地Maven仓库

转自：https://blog.csdn.net/ShuSheng0007/article/details/78547264/

第一种方案

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

• <path-to-file>: 要安装的JAR的本地路径
• <group-id>：要安装的JAR的Group Id
• <artifact-id>: 要安装的JAR的 Artificial Id
• <version>: JAR 版本
• <packaging>: 打包类型，例如JAR

最好在pom.xml文件所在的目录运行上述命令，个人经验不在根目录运行有时会安装不成功

执行上述命令后，我们就可以在pom.xml文件中引用

<dependency>
    <groupId>com.baidu.app</groupId>
    <artifactId>bdpush</artifactId>
    <version>3.0.1</version>
</dependency>

总结：这种方法弊端较大，程序的可维护性以及移植性较低。例如当你改变本地Maven仓库时需要重新安装。如果引用此JAR的项目是多人协调工作的项目，则每个人都要将其安装在自己的本地仓库。

解决办法

可以将此JAR文件放在工程的根目录下，让其随着项目走，然后在pom.xml文件中使用maven-install-plugin在Maven初始化阶段完成安装。

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-install-plugin</artifactId>
    <version>2.5</version>
    <executions>
        <execution>
            <phase>initialize</phase>
            <goals>
                <goal>install-file</goal>
            </goals>
            <configuration>
                <groupId>com.baidu.app</groupId>
                <artifactId>bdpush</artifactId>
                <version>3.0.1</version>
                <packaging>jar</packaging>
                <file>${basedir}/lib/bdpush-3.0.1.ja</file>
            </configuration>
        </execution>
    </executions>
</plugin>

${basedir}表示pom.xml文件所在的目录

第二种方案

第二种方法比较粗暴简单，具体为将依赖设置为系统域，通过完全路径引用。例如要引用的JAR文件在 <PROJECT_ROOT_FOLDER>/lib下，那么使用如下方法添加依赖

<dependency>
    <groupId>com.baidu.app</groupId>
    <artifactId>bdpush</artifactId>
    <version>3.0.1</version>
    <scope>system</scope>
    <systemPath>${basedir}/lib/bdpush-3.0.1.ja</systemPath>
</dependency>

${basedir}表示pom.xml文件所在的目录，例如你的JAR文件在D盘下的jarLibs里面，就将${basedir}替换为D:/jarLibs即可。

这种方法我自己在SpringBoot项目中打包成war文件时，没有成功打包到里面

第三种方案

第三种方案与第一种差不多，不同的是JAR文件被安装在一个单独的仓库里。这个本地仓库建在你项目的根目录下，随着项目走。例如

1：我们在${basedir}（pom.xml文件所在路径）目录下建立一个叫maven-repository的本地仓库。

2：使用如下命令安装我们要引用的JAR到此仓库中

mvn deploy:deploy-file -Dfile=<path-to-file> -DgroupId=<group-id> -DartifactId=<artifact-id> -Dversion=<version> -Dpackaging=jar -Durl=file:./maven-repository/ -DrepositoryId=maven-repository -DupdateReleaseInfo=true

3：在pom.xml中如下使用

• 申明仓库

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

• 然后添加引用

<dependency>
    <groupId>com.baidu.app</groupId>
    <artifactId>bdpush</artifactId>
    <version>3.0.1</version>
</dependency>
