Hello everyone, I would love to help develop Apache Spark. I have run into a (very basic?) issue which holds me in that mission.
I followed the `how to contribute` guide, however running ./build/mvn -DskipTests clean package fails with: [INFO] Using zinc server for incremental compilation [info] 'compiler-interface' not yet compiled for Scala 2.11.8. Compiling... error: scala.reflect.internal.MissingRequirementError: object java.lang.Object in compiler mirror not found. at scala.reflect.internal.MissingRequirementError$.signal(MissingRequirementError.scala:17) at scala.reflect.internal.MissingRequirementError$.notFound(MissingRequirementError.scala:18) at scala.reflect.internal.Mirrors$RootsBase.getModuleOrClass(Mirrors.scala:53) is it perhaps compability issue? Versions I use are as follows: ➜ spark git:(master) ✗ ./build/mvn --version Using `mvn` from path: /Users/tdudek/Programming/spark/build/apache-maven-3.3.9/bin/mvn Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T17:41:47+01:00) Maven home: /Users/tdudek/Programming/spark/build/apache-maven-3.3.9 Java version: 1.8.0_152, vendor: Oracle Corporation Java home: /Library/Java/JavaVirtualMachines/jdk1.8.0_152.jdk/Contents/Home/jre Default locale: en_PL, platform encoding: US-ASCII OS name: "mac os x", version: "10.13.1", arch: "x86_64", family: "mac" I just lost few hours mindlessly trying to make it work. I hate to waste other peoples' time and I'm REALLY ashamed at my question, but I think I am missing something fundamental. Cheers, Tomasz
