Decompression $m2_home/lib/maven-model-builder-3.0.jar
Find Org/apache/maven/model/pom-4.0.0.xml and you can see

Configuration of remote warehouses
In the project's Pom file

<Project>    ...    <repositories>        <Repository>            <ID>Jboss</ID>            <name>JBoss Repository</name>            <URL>http://repository.jboss.com/maven2/</URL>            <releases>                <enabled>True</enabled>            </releases>            <Snapshots>                <enabled>True</enabled>                <Updatepolicy>Daily</Updatepolicy>                <Checksumpolicy>Ignore</Checksumpolicy>            </Snapshots>            <Layout>Default</Layout>        </Repository>    </repositories></Project>

Updatepolicy-Check frequency of snapshots never,always,interval:x (minutes)
Checksumpolicy [Warn|fail|ignore]-maven examines inspection and file policies: When a build is deployed to a warehouse, the corresponding checksum files are deployed simultaneously. MAVEN validates checksum files while downloading artifacts

Certification of remote repositories
In the Settings.xml

<Settings>    ...    <Servers>        <Server>            <ID>Proj-releases</ID>            <username>User</username>            <Password>123456</Password>        </Server>    </Servers>    ...</Settings>

Deploy to remote warehouses
In the project's Pom file

<Project>    ...    <distributionmanagement>        <Repository>            <ID>Proj-releases</ID>            <name>Proj Release Repository</name>            <URL>Http://192.168.1.100/content/repositories/proj-releases</URL>        </Repository>        <snapshotrepository>            <ID>Proj-snapshots</ID>            <name>Proj Snapshots Repository</name>            <URL>Http://192.168.1.100/content/repositories/proj-releases</URL>        </snapshotrepository>    </distributionmanagement>    ...</Project>
