Spark compilation is currently based on Scala 2.10.4, and the installation of the Scala plug-in version is also 2.10.4, otherwise eclipse will report an error of incompatibility between the spark jar package and the scala version.

Different Eclipse versions of Scala IDE for Eclipse correspond to different plug-ins.
