conflicting cross-version suffixes Error in Apache Ignite

Question

I have a Spark Ignite program. When I use sbt to build the program, it reports error.

This is a very simple program, which is an empty project with just a sbt file.

build.sbt:

name := "testsss"

version := "1.0"

scalaVersion := "2.11.7"
libraryDependencies += "org.apache.spark" %% "spark-core" % "2.1.0"
libraryDependencies += "org.apache.spark" %% "spark-sql" % "2.1.0"
libraryDependencies += "org.apache.ignite" % "ignite-core" % "1.9.0"
libraryDependencies += "org.apache.ignite" % "ignite-indexing" % "1.9.0"
libraryDependencies += "org.apache.ignite" % "ignite-spark" % "1.9.0"

The error is

Error:Error while importing SBT project:

I checked. It seems that `"ignite-spark" % "1.9.0" used a different version of those conflict dependence with spark-core and spark-sql. How could I solve this?

This seems to be a bug in ignite-spark. It depends simultaneously on spark-unsafe_2.10 and scala-library 2.11.8, which should never happen. Report it and wait until a new version is released or workaround by getting its source code, fixing the spark-unsafe_2.10 dependency and recompiling (quite likely no source code fixes are needed).
