Object in compiler mirror not found - maven build
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

Or you just have zinc running but in a bad state. `zinc -shutdown` should
kill it off and let you try again.

I'm not seeing that on OS X or Linux. It sounds a bit like you have an old
version of zinc or scala or something installed.
