[WARNING]
[WARNING] It is highly recommended to fix these problems because they threaten 
the stability of your build.
[WARNING]
[WARNING] For this reason, future Maven versions might no longer support 
building such malformed projects.
[WARNING]
[WARNING] The project org.apache.orc:orc:pom:1.5.0-SNAPSHOT uses prerequisites 
which is only intended for maven-plugin projects but not for non maven-plugin 
projects. For such purposes you should use the maven-enforcer-plugin. See 
https://maven.apache.org/enforcer/enforcer-rules/requireMavenVersion.html
