Scala-cli doesn't output-coverage-out products.

[pikinier20]

Version(s)
checked on 0.1.2 and 0.1.5

Describe the bug

After adding:

//> using options "-coverage-out:scoverage.coverage"

and running:

scala-cli compile -S 3.nightly .

scala-cli passes the option to compiler but the scoverage.coverage directory is not present neither in cwd nor in the .scala-build directory
To Reproduce
GoodCoverage.scala

//> using options "-coverage-out:scoverage.coverage"
object GoodCoverage {

  def sum(num1: Int, num2: Int) = {
    if (0 == num1) num2 else if (0 == num2) num1 else num1 + num2
  }

}

scala-cli compile -S 3.nightly .

Expected behaviour
There should be a directory scoverage.coverage containing output from the compiler which is essential to check code coverage with e.g. scoverage.

Hi @pikinier20 , Thanks for reporting,
it seems that is also bloop issue as in #1023

There is exists a workaround and you have to use plain scalac without bloop. To disable using bloop you should use --server=false flag:

$ scala-cli compile -S 3.nightly . --server=false
$ ls
Hello.scala		scoverage.coverage

Hi @pikinier20,
Can you try to pass the absolute path to -coverage-out option? it should work when you pass the absolute path.

$ pwd
/tmp/scala-demo
$ cat Hello.scala 
//> using options "-coverage-out:/tmp/scala-demo/scoverage.coverage"
object GoodCoverage {

  def sum(num1: Int, num2: Int) = {
    if (0 == num1) num2 else if (0 == num2) num1 else num1 + num2
  }

}
$ scala-cli compile -S 3.nightly .

It should be fixed by #1080
