Thanks Sean. Reason I asked this is, in Building Spark documentation of 1.4.1, I still see this.
https://spark.apache.org/docs/latest/building-spark.html <https://spark.apache.org/docs/latest/building-spark.html> Building Spark using Maven requires Maven 3.0.4 or newer and Java 6+. But I noticed the following warnings from the build of Spark version 1.5.0-snapshot. So I was wondering if the changes you mentioned relate to newer versions of Spark or for 1.4.1 version as well. [WARNING] Rule 0: org.apache.maven.plugins.enforcer.RequireMavenVersion failed with message: Detected Maven Version: 3.2.5 is not in the allowed range 3.3.3. [WARNING] Rule 1: org.apache.maven.plugins.enforcer.RequireJavaVersion failed with message: Detected JDK Version: 1.6.0-36 is not in the allowed range 1.7.
