Exception in thread "main" java.util.concurrent.TimeoutException: Future timed out after [30 seconds]

Describe the bug Encountered a TimeoutException while running a Scala application utilizing the Bloop build server. The error occurred during communication via the Build Server Protocol (BSP). Specifically, the stack trace indicates a timeout during a call to ensure the correct version of Bloop is running.

To Reproduce

1. Install Scala-cli and set up a Scala project.
2. Configure ScalaTest as the testing framework for the project.
3. Execute ScalaTest tests using Scala-cli.
4. Observe the TimeoutException error occurring intermittently during test execution.

Request: Seeking guidance and assistance in resolving the encountered bugs to ensure smooth execution of ScalaTest tests with Scala-cli. Any insights, suggestions, or workaround solutions would be greatly appreciated.

Can't reproduce the problem.

Given the following code:

//> using dep "org.scalatest::scalatest::3.2.18"
import org.scalatest._
import org.scalatest.flatspec._
import org.scalatest.matchers._

class Tests extends AnyFlatSpec with should.Matchers {
  "A thing" should "thing" in {
    assert(2 + 2 == 4)
  }
}

the test runs smoothly from the command line:

scala-cli test smth.test.scala
# Compiling project (test, Scala 3.4.0, JVM (17))
# Compiled project (test, Scala 3.4.0, JVM (17))
# Tests:
# A thing
# - should thing
# Run completed in 71 milliseconds.
# Total number of tests run: 1
# Suites: completed 1, aborted 0
# Tests: succeeded 1, failed 0, canceled 0, ignored 0, pending 0
# All tests passed.

as well as in IDEA IntelliJ:

and in Metals

@kark7 Can you describe in more detail how do you replicate the timeout? what platform are you running on? A code snippet with the minimized issue would also be helpful.

@Gedochao , I am running on github runner with linux/amd64 platform.

[Gedochao]

Hm... it's hard to guess what could be causing the timeout without a code snippet. @kark7 can you try to minimize what part of the test could be causing this?

note: this shouldn't influence the behaviour, but v1.1.3 is an old version of Scala CLI, you can use v1.2.0 instead (and v1.2.1 is being released today)
