在idea中，利用maven插件时，对于多个maven子项目第一次打包(clear或者install)报错 parent.relativePath points at wrong local POM

经过一番百度操作,发现有两种解决方法,记录一下

1. 　　可先将下面的模块(modules)注释掉,再进行打包,打包完成后，放开注释，重新打包,就不会报错

(或者把父级pom文件直接拷贝到项目打包路径下也可以(如下代码的com/app/app-interf/1.0-SNAPSHOT目录下))

父pom文件

 
　　<modelVersion>4.0.0</modelVersion>
    <groupId>com.app</groupId>
    <artifactId>app-interf</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>pom</packaging>
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
    </properties>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.4.RELEASE</version>
        <relativePath/> 
    </parent>
    <developers>
        <developer>
        </developer>
    </developers>
    <modules>
        <module>jdbc</module>
        <module>util</module>
        <module>common</module>
    </modules>

子pom文件

    <modelVersion>4.0.0</modelVersion>
    <packaging>jar</packaging>
    <groupId>com.app.jdbc</groupId>
    <artifactId>jdbc</artifactId>
    <version>1.0-SNAPSHOT</version>
     <parent>
        <artifactId>app-interf</artifactId>
        <groupId>com.app</groupId>
        <version>1.0-SNAPSHOT</version>
        <relativePath/>
    </parent>

2.　　在子pom文件中,配置<relativePath>属性

    <modelVersion>4.0.0</modelVersion>
    <packaging>jar</packaging>
    <groupId>com.app.jdbc</groupId>
    <artifactId>jdbc</artifactId>
    <version>1.0-SNAPSHOT</version>
     <parent>
        <artifactId>app-interf</artifactId>
        <groupId>com.app</groupId>
        <version>1.0-SNAPSHOT</version>
        <relativePath>../pom.xml</relativePath>
    </parent>
