             Summary: Building Spark with SBT unsuccessful when source code in Mllib is modified, But with MVN is ok
                 Key: SPARK-21631
                 URL: https://issues.apache.org/jira/browse/SPARK-21631
             Project: Spark
          Issue Type: Bug
          Components: Build, MLlib
    Affects Versions: 2.1.1
         Environment: ubuntu 14.04

Spark 2.1.1

MVN 3.3.9

scala 2.11.8
            Reporter: Sean Wong


I added 
import org.apache.spark.internal.Logging
at the head of LinearRegression.scala file

Then, I try to build Spark using SBT.
However, here is the error:
*[info] Done packaging.

[error] (mllib/*:scalaStyleOnCompile) errors exist*

After this, I switch to use MVN to build Spark, Everything is ok and the building is successful.

So is this a bug for SBT building?
