If it comes with a parent, the best practice is not to let you encounter this kind of pit and know more about it.

Change it into this

<?XML version= "1.0" encoding= "UTF-8"?><Projectxmlns= "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">        <groupId>Oxgren</groupId>        <version>1.0-snapshot</version>       <Artifactid>Oxgren-common</Artifactid>       <modelversion>4.0.0</modelversion>    <Dependencies>        <Dependency>            <groupId>Javax.mail</groupId>            <Artifactid>Mail</Artifactid>            <version>1.4.7</version>        </Dependency>    </Dependencies></Project>

Problem solved.

A namespace conflict was suspected
