Description
Hi,
The change in #1175 doesn't actually change the working directory when you run from a sub-project. Relative paths are still relative to the project root; it's only when they're canonicalized (getAbsolutePath for example) that they are reinterpreted as being rooted at user.dir.
Here is a little program, in subproject main under modules/main in my project:
object Test {
def main(args: Array[String]): Unit = {
val cwd = new java.io.File(".")
println(cwd.getAbsolutePath)
println(cwd.listFiles().toList)
}
}When when I run it I see this:
itac (cli *)$ bloop run main -m Test
/Users/rnorris/Scala/itac/.
List(./target, ./src)
However they don't correspond as expected.
itac (cli *)$ ls /Users/rnorris/Scala/itac/.
arch/ build.sbt modules/ project/ src/ target/ work/
Running from sbt gives the expected result.
tac (cli *)$ sbt "main/runMain Test"
[info] Loading global plugins from /Users/rnorris/.sbt/1.0/plugins

/Users/rnorris/Scala/itac/.

itac (cli *)$
There is a JDK issue about this and the evaluation begins:
"user.dir", which is initialized during jvm startup, should be used as an
informative/readonly system property, try to customize it via command line
-Duser.dir=xyz will end up at implementation dependend/unspecified behavior.
So I think bloop shouldn't do this. Instead is it possible to set cwd in the process builder?
Thanks!
