1. scope标签的作用
2、使用system标签
项目三方jar存放位置结构：
pom.xml中引入三方jar：
<dependency><groupId>test</groupId><artifactId>testa</artifactId><version>0.0.1</version><scope>system</scope><systemPath>${project.basedir}/src/main/resources/lib/test.jar</systemPath>
</dependency>
pom.xml中的打包构建配置：
<build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><configuration><includeSystemScope>true</includeSystemScope><!-- 是否限制解压缩 --><executable>false</executable><mainClass>com.tuijie.gainguest.GainguestApplication</mainClass></configuration><executions><execution><goals><goal>repackage</goal></goals></execution></executions></plugin></plugins><resources><!-- 用于排除三方jar包打包进入BOOT-INF/classes下(运行时是用不到的) --><resource><directory>src/main/resources</directory><filtering>false</filtering><excludes><exclude>lib/*.jar</exclude></excludes></resource></resources>
</build>
重点：
<includeSystemScope>true</includeSystemScope>
和
<excludes><exclude>lib/*.jar</exclude>
</excludes>
