cpp build task does not work

[simark]

Description

I have this in my workspace preferences:

{
   "cpp.buildConfigurations": [
      {
         "name": "/home/smarchi/build/babeltrace",
         "directory": "/home/smarchi/build/babeltrace",
         "commands": {
             "build": "make"
         }
      }
   ]
}

This generates a task in the task runner:

First, notice the undefined, I don't think it's intended for it to be there. Then, when I try to run it, nothing happens and I get this in the console:

task ERROR Can't get task launch configuration for label: C/C++ Build - /home/smarchi/build/babeltrace

I am at the following commit:

I made this change elaihau@d080d6a which fixed the display issue (i.e., undefined: C/C++ in task label). Also the Can't get task launch configuration for label: C/C++ Build error that Simon mentioned above was gone.

Instead I was getting this error

task INFO Created new task, id: 4, process id: 13, OS PID: 15131, context: file:///home/elaihau/dev/test-dir
terminal ERROR Couldn't attach - can't find terminal with id: 13 
root ERROR Couldn't resize terminal -1, because it doesn't exist.
terminal ERROR Error attaching to terminal id 13, the terminal is most likely gone. Starting up a new terminal instead.

I know this looks like the problem of "the command finishes (too quickly) before it gets attached to the terminal", but my task was defined like this in the pref:

   "cpp.buildConfigurations": [{
     "name": "Simon task runs",
     "directory": "/home/elaihau/dev",
     "commands": {
       "build": "bash -c 'sleep 5 && ls'"
     }
   }]

"sleep 5" should be more than enough ... do you have any ideas of what could go wrong ? @vince-fugnitto @marechal-p

I don't really know, but I just wanted to mention that you could just use:

"build": "sleep 5 && ls"

That command is already interpreted by a shell.

i got exactly the same error if i use sleep 5 && ls

i used bash -c because i wasn't sure if the error was caused by the command not interpreted properly :)
