I'm trying to develop a project with Maven, which also involves Jetty as a servlet container. But in build time appear warnings like "scanned from multiple locations" which involves a location in the .m2 directory and a location in the target directory created. I'm not sure if they are triggered by using Jetty. How can these warnings be solved?

Change the setting useManifestOnlyJar to false in the POM, around the tags: 

<project>
  [...]
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-failsafe-plugin</artifactId>
        <version>2.12.4</version>
        <configuration>
          <useManifestOnlyJar>false</useManifestOnlyJar>
          <useSystemClassLoader>false</useSystemClassLoader>
        </configuration>
      </plugin>
    </plugins>
  </build>
  [...]
</project>

If you want ignore the WARN log, you can append below code in start.ini file:

--exec
-Dorg.eclipse.jetty.annotations.AnnotationParser.LEVEL=OFF
