springboot 多模块项目打包时遇到

[ERROR]     'packaging' with value 'jar' is invalid. Aggregator projects require 'pom' as packaging. @ line 3, column 102

在 parent 项目中的 pom.xml

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.2.5.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.abc</groupId>
    <artifactId>conve</artifactId>
    <version>1.0</version>
    <name>convert</name>
    <description>conve</description>

    <properties>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>
        ……
    </dependencies>

    <modules>
        <module>multiple</module>
        <module>single</module>
    </modules>
　　……

默认打包类型为 jar

<packaging>jar</packaging>

解决的方法：

　　修改打包类型 pom

<packaging>pom</packaging>
