Trying to just grab some files from the root level directory of my project (same level as build.sbt) and put them into my docker image using the copy instruction from sbt-docker plugin but getting a files not found error. My code looks like this to try and jump out to the main level val sparkDir = baseDirectory.value / "../spark-2.4.1-bin-hadoop2.7" but keep running into this error:

${HOME}/root/submodule/../spark-2.4.1-bin-hadoop2.7/jars: no such file or directory

How do I instruct sbt docker using sbt dsl to just copy files in the following manner: copyRaw(sparkDir + "/jars", "/opt/spark/jars")
