Maven项目模块打包引入

工作中我们会遇到这样的一种场景，就是写好的代码封包给别的部门使用或者项目使用，如果我们此时按照正常的打包流程的话，对方是可以使用maven引入包的，但是包内的类缺无法引入使用，此时就需要我们下面所说的这种方式来解决

问题

maven可以引入，却不能 import 类使用

解决

• 首先还是新建一个模块测试，license-common,修改pom.xml中的打包插件为下面这种

      <groupId>com.zuiyu</groupId>
      <artifactId>license-common</artifactId>
      <version>0.0.1-SNAPSHOT</version>
      <name>license-common</name>
      
  <build>
          <plugins>
              <plugin>
                  <groupId>org.apache.maven.plugins</groupId>
                  <artifactId>maven-compiler-plugin</artifactId>
                  <version>3.8.1</version>
                  <configuration>
                      <source>1.8</source>
                      <target>1.8</target>
                      <encoding>UTF-8</encoding>
                  </configuration>
              </plugin>
          </plugins>
      </build>

• 执行idea中的打包，也就是mvn install

• 需要该模块代码的项目pom中加入

      <dependency>
              <groupId>com.zuiyu</groupId>
              <artifactId>license-common</artifactId>
              <version>0.0.1-SNAPSHOT</version>
              <scope>compile</scope>
          </dependency>

总结

完整的核心pom文件如下,只保留打包相关
