Maven: "Could not find artifact package:jar:1.0-SNAPSHOT"?

Question

I've tried installing a Spring project, and had one created from start.spring.io. However, when trying to run mvn clean install , I have run into errors:

Could not find artifact com.sof:game-mix:jar:1.0-SNAPSHOT

I know this is has happened to others, and I've checked these threads for more information but unfortunately my attempts to replicate their solutions haven't worked for me.

Here is a link to my project , for anyone who wishes to replicate the project and see if mvn clean install might work for them. Otherwise, the code for my pom.xml files is below

I have three pom.xml files:

Root pom.xml:

<?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"

    </modules>

    <properties>

</project>

My web module's pom.xml:

<project xmlns="http://maven.apache.org/POM/4.0.0"

</project>

And my core module's pom.xml:

<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <parent>
        <artifactId>game-mix</artifactId>
        <groupId>com.sof</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>core</artifactId>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>

        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
        </dependency>
    </dependencies>


</project>

Where exactly am I going wrong? I'd appreciate any assistance

Answer 1

I deleted my first answer because I did not read your POMs thoroughly enough.

com.sof:game-mix:jar:1.0-SNAPSHOT is your parent POM. You cannot reference it as a <dependency> .
