steps

• write a type error in build.sbt
• test it with "sbt -batch test"
• the last line always contains "Project loading failed: (r)etry, (q)uit, (l)ast, or (i)gnore? (default: r)"

problem

In batch mode this prompt should be omitted, as batch mode has no user interaction.

this prompt also caused IntelliJ Scala plugin to hang indefinitely, unable to proceed:

expectation

remove this line in batch mode
