Woops, wanted to include this too:
at scala.Predef$.assert(Predef.scala:179)
at com.github.shivawu.sbt.maven.Pom$.apply(Pom.scala:236)
at com.github.shivawu.sbt.maven.MavenPlugin$.(MavenPlugin.scala:16)
at com.github.shivawu.sbt.maven.MavenPlugin$.(MavenPlugin.scala)
java.lang.AssertionError: assertion failed: [/tmp/ensime_update_31930x7c/./pom.xml] doesn't exist
I think maybe we just need to change the reference from relative to absolute? Working on a fix.
