There is a Maven limitation that prevents "mvn compile" from building and using the hadoop-maven-plugins module in the reactor for use by subsequent modules. This does not impact other targets like "mvn test" or "mvn install", and a standard work-around is to run an initial "mvn install" from the top level of the source tree before trying to do anything else.
I recommend running "mvn clean install -DskipTests -Dmaven.javadoc.skip=true" as your first step. This will ensure hadoop-maven-plugins gets installed into your local Maven repository cache on disk. After that, you'll be able to do faster incremental builds by running "mvn compile" or building only a specific sub-module, and Maven will be able to find hadoop-maven-plugins from the local repository cache. --Chris Nauroth From: Boric Tan <[email protected]<mailto:[email protected]>> Date: Thursday, January 14, 2016 at 1:09 PM To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Subject: Help for a hadoop build error: "Failed to parse plugin descriptor for org.apache.hadoop:hadoop-maven-plugins:2.7.1" Hi there, I was trying to build Hadoop 2.7.1 source from scratch on a Ubuntun 14.04 machine. I was following the instructions from BUILDING.txt. After installed all required packages, I used the following command under /hadoop-2.7.1-src. $mvn compile -e And it returned an error message shown below. ****************************************** [INFO] Apache Hadoop Common ..............................
