Hello, Following the instructions for building spark 1.0.0, I encountered the following error:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.7:run (default) on project spark-core_2.10: An Ant BuildException has occured: Please set the SCALA_HOME (or SCALA_LIBRARY_PATH if scala is on the path) environment variables and retry. [ERROR] around Ant part ...<fail message="Please set the SCALA_HOME (or SCALA_LIBRARY_PATH if scala is on the path) environment variables and retry.">... @ 6:126 in /Users/soren/src/spark-1.0.0/core/target/antrun/build-main.xml No where in the documentation does it mention that having scala installed and either of these env vars set nor what version should be installed. Setting these env vars wasn't required for 0.9.1 with sbt. I was able to get past it by downloading the scala 2.10.4 binary package to a temp dir and setting SCALA_HOME to that dir. Ideally, it would be nice to not have to require people to have a standalone scala installation but at a minimum this requirement should be documented in the build instructions no? -Soren
