eclipse把maven配置引入本地jar包，打war包时打到lib

正常<scope>system</scope>的依赖是不会打进包的

假设项目中有个jar包(gson-2.8.5.jar)需要通过<scope>system</scope>的形式打包

如果你的项目打的是jar包

    <packaging>jar</packaging>

那么配置<includeSystemScope>true</includeSystemScope>就可以把jar打进去

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

如果你的项目打的是war包

 <packaging>war</packaging>

如果配置了<includeSystemScope>true</includeSystemScope>

打war包不会将本地jar包打入\WEB-INF\lib 下，而是在 \WEB-INF\lib-provided 下

需要在 <build> <plugins> 下添加或修改maven-war-plugin配置

<directory></directory> 内为你项目里存放lib的路径，这里是src/main/resources/lib

<targetPath></targetPath> 是目标路径，打入 WEB-INF/lib/

<include></include> 所有jar包

 <plugin> 
    <groupId>org.apache.maven.plugins</groupId>  
    <artifactId>maven-war-plugin</artifactId>  
    <configuration> 
      <webResources> 
        <resource> 
          <directory>src/main/resources/lib</directory>  
          <targetPath>WEB-INF/lib/</targetPath>  
          <includes> 
            <include>**/*.jar</include> 
          </includes> 
        </resource> 
      </webResources> 
    </configuration> 
  </plugin>

附：maven配置引入本地jar包

假设项目中需要引入本地ar包(gson-2.8.5.jar)

首先配置一个基础路径

<properties>
    <locallib.path>${project.basedir}/src/main/resources/lib</locallib.path>
</properties>

然后配置项目路径中的jar包

<dependency>
    <groupId>com.google.code.gson</groupId>
    <artifactId>gson</artifactId>
    <version>2.8.5</version>
    <scope>system</scope>
    <systemPath>${locallib.path}/gson-2.8.5.jar</systemPath>
</dependency>

或者直接指定路径

		<!-- 浙江政务2.0 -->
        <dependency>
            <groupId>com.alibaba.gov</groupId>
            <artifactId>atg-sdk-java</artifactId>
            <version>RELEASE20210107143535</version>
            <scope>system</scope>
            <systemPath>${project.basedir}/src/main/resources/lib/atg-sdk-java-RELEASE20210107143535.jar</systemPath>
        </dependency>

加了plugin之后可能会报错
