Hi Spark Devs, Hoping someone cane help me out. No matter what I do, I cannot get Intellij to build Spark from source. I am using IDEA 13. I run sbt gen-idea and everything seems to work fine.
When I try to build using IDEA, everything compiles but I get the error below. Have any of you come across the same? ====== Internal error: (java.lang.AssertionError) java/nio/channels/FileChannel$MapMode already declared as ch.epfl.lamp.fjbg.JInnerClassesAttribute$Entry@1b5b798b java.lang.AssertionError: java/nio/channels/FileChannel$MapMode already declared as ch.epfl.lamp.fjbg.JInnerClassesAttribute$Entry@1b5b798b at
