Error building Apache Spark

Question

I've been successfully using a version of Spark from AmpCamp to build and run a couple of projects. I am now trying to use a newer version of Spark, 1.2.1, but can't seem to get it to build.

Environment:

$ mvn --version
Apache Maven 3.0.5
Maven home: /usr/share/maven
Java version: 1.8.0_31, vendor: Oracle Corporation
Java home: /usr/lib/jvm/jdk1.8.0_31/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.13.0-45-generic", arch: "amd64", family: "unix"

$ echo $JAVA_HOME
/usr/lib/jvm/jdk1.8.0_31

$ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/lib/jvm/jdk1.8.0_31/bin:/usr/lib/jvm/jdk1.8.0_31/db/bin:/usr/lib/jvm/jdk1.8.0_31/jre/bin:/usr/lib/jvm/jdk1.8.0_31/bin:/usr/lib/jvm/jdk1.8.0_31/db/bin:/usr/lib/jvm/jdk1.8.0_31/jre/bin

$ ant -version
Apache Ant(TM) version 1.9.3 compiled on April 8 2014

Note: tried "mvn -Pyarn -Phadoop-2.5 -Dhadoop.version=2.5.0 -Dscala-2.11 -X -DskipTests clean package" with the same results shown below.

$ mvn -DskipTests clean package

I initially had been using JRE in my JAVA_HOME. Read the post Error building Spark with Maven ; followed the same advice, even though I had no errors finding javac; but am still getting the same error.

Suggestions??

Updated with -X output

Answer 1

I uninstalled maven and ant. Installed maven and configured my settings.xml per our company configuration and am now able to build spark. Perhaps the local install of ant that I had was causing problems, or there was a mismatch in the version of ant that I had installed and what as called out in the pom.xml file.
