How can I enable remote debugging for SBT in windows?

Question

I would like to accomplish running the equivalent of this

sbt -jvm-debug 5005

However I don't seem to be able to pass in args in Windows. This is what I am seeing

>sbt -jvm-debug 5005
[info] Loading project definition from [myProject]
[info] Set current project to [myProject] (in build file myProject)
[error] Expected letter
[error] Expected symbol
[error] Expected '!'
[error] Expected '+'
[error] Expected '++'
[error] Expected ';'
[error] Expected end of input.
[error] Expected 'show'
[error] Expected '*'
[error] Expected '{'
[error] Expected project ID
[error] Expected configuration
[error] Expected key
[error] 5005
[error] ^
[error] Not a valid command: jvm-debug
[error] Not a valid project ID: jvm-debug
[error] Expected ':' (if selecting a configuration)
[error] Not a valid key: jvm-debug
[error] jvm-debug
[error]          ^                  

I would like to be able to remote debug this application from Intellij. Any help would be great!

Solution 1

Seems like the Windows version of SBT doesn't define this functionality.

On Linux it is defined in the $SBT_HOME/sbt/bin/sbt-launch-lib.bash as

addDebugger () {   
  addJava "-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=$1" 
}

You can achieve the same result by setting the SBT_OPTS environmental variable on Windows.

Run SBT like this, to make the debugger listen on port 5005

set SBT_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005" && sbt

Solution 2

set SBT_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005
sbt run

was the only working solution on Windows 7.

Solution 3

Currently, I'd downloaded the last updated sbt, exactly sbt 1.3.3 but when I want to enable debug in the project, I had the same problem as you. Investigating, I could see that I haven't this file (sbt-launch-lib.bash) in my own root C:\Program Files (x86)\sbt\bin so when I see in another machine, I could notice that sbt, It was 1.2.8 and yes it had the file that I mentioned before so I uninstalled sbt 1.3.3 and I installed sbt 1.2.8 and put in my project sbt -jvm-debug 9999 and it works.

What does that "&& sbt" at the end of the line mean? doesn't seem like a valid option to me.

On Linux it executes second command (sbt in this case) if the first command succeeded. Maybe in fact this doesent work on Windows (I dont remember, and I cannot check now). However just skip && and eexecute set and sbt as two separate commands. One after another.

Does not work (anymore?) on Windows 10 and sbt version 1.3.13.
