thanks for responding. I’d like to have the effect that you change a source file, compile with pants, and your JVM immediately sees the change. jrebel does this by having a

rebel.xml

file that configures where they should watch for changed class files. For pants, I was thinking the closest to that would be to watch all the

current

directories in .pants.d. If you compile, the sources are new, so pants would create a new directory, compile into it, and point

current

there. seems like that would work.
