(转)通过maven，给没有pom文件的jar包生成pom文件，maven项目引入本地jar包

问题一：

经常遇到公司私服或者中央仓库没有的jar包，然后通过各种渠道找到了解决问题的jar包，但是发现没有pom文件，maven项目引入之后，还有maven在本地仓库找不到对应jar包的pom文件，打包的时候会在私服下载对应jar包的pom文件而抛出异常，通过maven就可以解决这个问题。前提是你安装了maven，然后在命令行执行命令就OK了！！！

命令：

mvn install:install-file -DgroupId=novaplanet.net -DartifactId=commons-lang -Dversion=2.5 -Dfile=F:/commons-lang-2.5.jar -Dpackaging=jar -DgeneratePom=true
DgroupId：是项目组织唯一的标识符，自己随便起名
DartifactId：项目的唯一的标识符，自己可以随便起
Dversion：项目版本
Dfile：jar包路径（绝对路径）
DgeneratePom：是否生成pom文件，ture:生成，false：不生成

执行成功，会在本地的maven jar包目录下以下结果

问题二：

自己本地的jar包，公司私服上没有，引入本地的jar包，现在项目的resource目录下新建lib文件夹，然后将你本地的jar包copy到里面

在maven的配置如下：

<dependencies>
        <dependency>
            <groupId>novaplanet.net</groupId>
            <artifactId>javapns-jdk16-163</artifactId>
            <version>1.2</version>
            <scope>system</scope>
            <systemPath>${project.basedir}/src/main/resources/lib/javapns-jdk16-163-1.2.jar</systemPath>
        </dependency>
    </dependencies>

build插入下面配置：

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <includeSystemScope>true</includeSystemScope>
                </configuration>
            </plugin>
        </plugins>
    </build>

我的实例配置：

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

引入之后，编译项目，编译成功不一定引入成功了，接着打包，看jar包中的classes下的lib中有没有你需要引入的jar包
