mvn clean spring boot:run
必须从包含
SpringBoot应用程序的模块执行

您可以从父pom执行它。

从
模块1
执行此命令，它应该可以工作

顺便说一下，
module1
pom.xml中的重复声明不是必需的，因为您的家长已经指定了它：


 <build>
    <plugins>
        <plugin>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.1</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
            </configuration>
        </plugin>
    </plugins>
</build>




maven编译器插件
3.1
1.8
1.8

我就是这样做的

从多模块项目的根目录运行以下命令：


mvn -pl module1 spring-boot:run


现在，如果在多模块spring boot项目的根目录中有一个
config
文件夹，spring boot还将扫描该文件夹中的属性文件（src/main/resources除外），使这些属性对所有模块都是全局的
