maven build issue for parent child modules

I have a maven parent pom as :

    <?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>groupId</groupId>
    <artifactId>spark_argo_test</artifactId>
    <packaging>pom</packaging>
    <version>1.0-SNAPSHOT</version>
    <modules>
        <module>src/modules/spark_stage1</module>
        <module>src/modules/spark_stage2</module>
    </modules>
    <properties>

The child module is as :

 <?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>spark_argo_test</artifactId>
        <groupId>groupId</groupId>
        <version>1.0-SNAPSHOT</version>
        <relativePath>pom.xml</relativePath>
    </parent>
    <modelVersion>4.0.0</modelVersion>
    <artifactId>spark_stage1</artifactId>
    <packaging>jar</packaging>
    <properties>
        <maven.compiler.source>11</maven.compiler.source>
        <maven.compiler.target>11</maven.compiler.target>
    </properties>

when i build this i get following error as :

     mvn clean package -DskipTests=clear

Kindly check the relative path in your child poms

<relativePath>pom.xml</relativePath>

I think you are referencing to this pom only. Maybe you, meant it to be

 <relativePath>../pom.xml</relativePath>
