Spark SQL 1.5 build failure

Question

I've installed Spark 1.5 on Ubuntu 14.04 LTS. When running build with command build/mvn -Dscala-2.11 -DskipTests clean package I get the following build error during project Spark SQL:

    [error] missing or invalid dependency detected while loading class file 'WebUI.class'.
        [error] Could not access term eclipse in package org,
        [error] because it (or its dependencies) are missing. Check your build definition for
        [error] missing or conflicting dependencies. (Re-run with `-Ylog-classpath` to see the problematic classpath.)
        [error] A full rebuild may help if 'WebUI.class' was compiled against an incompatible version of org.

Here below my env variables in file .bashrc

export JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-amd64

export SCALA_HOME=/usr/local/src/scala/scala-2.11.7
export PATH=$SCALA_HOME/bin:$PATH
export PATH=/home/ubuntu/apache-maven-3.3.3/bin:$PATH

export SPARK_HOME=/home/ubuntu/spark-1.5.0
export MAVEN_OPTS="-Xmx2g -XX:MaxPermSize=512M -XX:ReservedCodeCacheSize=512m"

Update: tried to run with -Ylog-classpath, but didn't work:

Unable to parse command line options: Unrecognized option: -Ylog-classpath

Answer 1

Just run ./dev/change-scala-version.sh 2.11 from your spark directory to switch all the code to 2.11. Then run mvn (3.3.3+) or make-distribution.sh with your flags set.

Answer 2

Refer to Angelo Genovese's comment, do not include -Dscala-2.11 in build command.
