I have checked out from master, cleaned/rebuilt on command line in maven, then cleaned/rebuilt in intellij many times. This error persists through it all. Anyone have a solution?

After having checked out from master/head the following error occurs when attempting to run any test in Intellij

Exception in thread "main" java.lang.NoClassDefFoundError: com/google/common/util/concurrent/ThreadFactoryBuilder
at org.apache.spark.util.Utils$.<init>(Utils.scala:648)


There appears to be a related issue/JIRA:


https://issues.apache.org/jira/browse/SPARK-3217


But the conditions described do not apply in my case:

 Did you by any chance do one of the following:

  • forget to "clean" after pulling that change
  • mix sbt and mvn built artifacts in the same build
  • set SPARK_PREPEND_CLASSES

For reference here is the full stacktrace:
