</project>

下面开始测试，目前spring-boot-maven-plugin在父pom文件上，执行后报错找不到main class文件：Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.4.4:repackage (default) on project common: Execution default of goal org.springframework.boot:spring-boot-maven-plugin:2.4.4:repackage failed: Unable to find main class

springboot多模块打包的记录是怎样的

按照提示，在父pom.xml中增加main class的配置

<plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <mainClass>com.hs.demo.DemoApplication</mainClass>
                    <layout>ZIP</layout>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

这会报了4个错误，都是报包不存在的

继续测试，把spring-boot-maven-plugin放到主工程的pom中去

最终controller工程的pom.xml如下：

</project>

继续测试，打包成功，文件大小正常

这个repackage有什么用呢？去了试试，最终变成这样

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

同样也打包成功，只不过主工程的jar大小有点问题，只有4kb

看看官网对这个的解释：https://docs.spring.io/spring-boot/docs/2.4.4/maven-plugin/reference/htmlsingle/#repackage-example-exclude-dependency

这个其实就是把所有依赖的jar包都打进来。
