Without specifying <packaging>xxx</packaging> in pom, the default is jar.

For project1, it is deployed to nexus. Then project2 can uses it as normal dependency rather than parent. project2 can still uses the version, scope inside dependencyManagement in project1. See below.

project1/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"

    </properties>

    <dependencyManagement>

    </dependencies>

</project>

 

project2/pom.xml

<?xml version="1.0" encoding="UTF-8"?>

        <pluginRepository>
            <id>xxx</id>

            <url>http://nexus.xxx.com</url>
        </pluginRepository>

</project>

When running mvn dependency:tree, it shows below. It actually same as result in dependencyManagement vs dependencies
