I have a build task that takes at least 2 seconds to finish in tasks.json.
I also have different very quick task for cleaning some files in tasks.json.
I have 3 configurations in launch.json: server, server_running_on_top_of_server and client. All of them can be running separately, so all of them should have the build as a preLaunchTask.
So if I run those 3 configurations separately with build as preLaunchTask and cleaning specified in dependsOn of build, it's quite fine.
But when I want to run those 3 configurations together as a compound, it's not very intuitive. I would like to first run build task and then server and after the server is up, then server_running_on_top_of_server and client. The cleaning configuration should be run only for the client, but can be run everytime the build task is run.
"compounds": [
{
"name": "server, server_running_on_top_of_server and client",
"configurations": ["server", "server_running_on_top_of_server", "client"]
}
and
"tasks": [
{
"label": "build",
"type": "shell",
"command": "make",
"args": [
"-j4",
"debug"
],
"group": {
"kind": "build",
"isDefault": true
},
"dependsOn": "delete something",
"presentation": {
"panel": "shared"
}
},
{
"label": "delete something",
"type": "shell",
"command": "rm",
"args": [
"-f", "something"
],
"presentation": {
"panel": "shared"
}
},
{
"label": "wait 5 seconds",
"type": "shell",
"command": "sleep",
"args": [
"5"
]
}
]
But the build task is run 3 times this way and also separately in 3 terminals even with presentation.panel: "shared" so it uses 12 cores instead of 4 so it totally lags my PC. How to fix that?
And how to run the remaining 2 configurations after the server is up? Is there a better approach than to create another task that just waits some time?
Is there a possibility to specify more than 1 task in preLaunchTask? So I can assign build and cleaning task only for client.

I had a custom build system in sublime for C++ which takes input from one file and redirects the output to another.
My sublime build system is as follows :
{
"cmd": ["g++.exe","-std=c++14", "${file}", "-o", "${file_base_name}.exe", "&&" , "${file_base_name}.exe<inputf.in>outputf.in"],
"selector":"source.cpp",
"shell":true,
"working_dir":"$file_path"
}
this helped in taking input from "inputf.in" file and print the output in "outputf.in" whenever i ran my program.
I want similar functionality in vs code but dont know how to configure build-task.
Here is a build task for a Node addon, you have to put it in .vscode/tasks.json:
{
"version": "2.0.0",
"tasks": [
{
"label": "Build",
"type": "shell",
"command": "npx node-pre-gyp build -j max",
"problemMatcher": {
"base": "$gcc",
"fileLocation": [
"relative",
"${workspaceFolder}/build"
]
},
"group": {
"kind": "build",
"isDefault": true
}
}
]
}
You can press Ctrl-Shift-P to bring the command palette and select configure build task.
The problem matcher allows VSCode to highlight the compiler errors in your editor.
The default build task is the one you launch with a hotkey.
I would like to configure one task labeled "Build and then Run" that would execute a specific build task and then run the executable. I thought that the dependsOn property was what I was looking for but as it turns out it runs the tasks in parallel instead.
Here is an example of tasks.json:
{
"version": "2.0.0",
"tasks": [
{
"label": "Build",
"type": "shell",
"command": "g++ -g ${workspaceFolder}/main.cpp -o ${workspaceFolder}/main.exe",
"problemMatcher": "$gcc"
},
{
"label": "Run",
"type": "shell",
"command": "${workspaceFolder}/main.exe"
},
{
"label": "Build and then Run",
"type": "shell",
"dependsOn": [ // <------ important
"Run",
"Build"
]
}
]
}
It doesn't matter in what order I put the tasks into the dependsOn array. The "Run" task executes with error because the "Build" task creates the executable too late.
Is there some property or trick that allows two tasks to run in sequence?
{
"label": "Build and then Run",
"type": "shell",
"dependsOrder": "sequence", <= `parallel must be the default
"dependsOn": [
"Run",
"Build"
]
}
If you specify "dependsOrder": "sequence" then your task dependencies
are executed in the order they are listed in dependsOn. Any
background/watch tasks used in dependsOn with "dependsOrder":
"sequence" must have a problem matcher that tracks when they are
"done".
from https://code.visualstudio.com/Docs/editor/tasks#_compound-tasks
That implies to me, plus your experience, that omittiing the option dependsOn means by default the tasks will run in parallel, not in sequence.
Visual Studio Code was just updated to allow running a task and having them open in a split terminal. This is great, however I'm looking for one more thing to make this perfect.
I would like to be able to open a total of 3 terminals via a task. One for my NPM build, one for my backend MAVEN build, and a third that is just a blank new terminal I can use for git commands when needed.
I can't seem to find a way to tell VSC to run a task that just opens a new terminal ready to use without providing it a command. I would even settle with giving it a simple command like "node -v" just to start it out, as long as that panel is still usable after. Right now it wants to close it after it has ran.
Here is my task setup: I have one task setup as the build task that depends on two others. I envision adding a third one to that which would just open the new terminal:
{
"version": "2.0.0",
"tasks": [
{
"label": "Run Maven and NPM",
"dependsOn": [ "maven", "npm" ],
"group": {
"kind": "build",
"isDefault": true,
},
},
{
"label": "maven",
"command": "...",
"type": "shell",
"presentation": {
"reveal": "always",
"group": "build"
},
"options": {
"cwd": "${workspaceRoot}/server"
}
},
{
"label": "npm",
"type": "shell",
"command": "ng serve --port 4203 --proxy-config proxy.conf.json",
"presentation": {
"reveal": "always",
"group": "build"
},
"options": {
"cwd": "${workspaceRoot}/client-APS"
}
}
]
}
The following should work:
{
"type": "process",
"label": "terminal",
"command": "/bin/bash", // <-- your shell here
"args": [
"-l" // login shell for bash
],
"problemMatcher": [],
"presentation": {
"echo": false, // silence "Executing task ..."
"focus": true,
"group": "build", // some arbitrary name for the group
"panel": "dedicated"
},
"runOptions": {
"runOn": "folderOpen"
}
}
I was trying to achieve something very similar when I stumbled my way into this solution: Here, I'm auto-launching (and setting the focus on) the terminal when the folder is opened in vscode -- and further tasks that share the same presentation.group gets placed in split terminals when they're run (with new vs. reused splits depending on their presentation.panel)
(The runOptions bit is superfluous for your case, but I'm keeping it in case it is helpful for someone)
Note: For this example, you may or may not need the -l option depending on your settings for terminal.integrated.shell*, terminal.integrated.automationShell* and terminal.integrated.inheritEnv -- this issue has some discussion on what is involved in setting up the shell environment.
Using tasks.json version 2.0.0, I have not been able to make it so that, when I build my application, multiple tasks are run at the same time. I'm using gulp for my SCSS compilation, and running my Compile/minify cms.scss task on its own works fine, so it's not a problem with the task itself, just VS Code's task runner. When I Run Build Task in VS Code, my gulp task is not being run, even though it has "group": "build" — only the dotnet one is.
tasks.json
{
"version": "2.0.0",
"tasks": [
{
"label": "build",
"command": "dotnet",
"type": "process",
"args": [
"build",
"${workspaceFolder}/HpsCoreWeb.csproj"
],
"problemMatcher": "$msCompile",
"group": {
"kind": "build",
"isDefault": true
}
},
{
"label": "Compile/minify cms.scss",
"type": "gulp",
"task": "cms.scss:cms.min.css",
"problemMatcher": "$node-sass",
"group": "build"
}
]
}
According to the VS Code Tasks documentation:
group: Defines to which group the task belongs. In the example, it belongs to the test group. Tasks that belong to the test group can be executed by running Run Test Task from the Command Palette.
The dotnet build task is succeeding, so shouldn't the other task, which is also part of the build group, be run as well? What am I doing wrong?
The problem is that "Run Test Task" and "Run Build Task" do not execute all tasks in that specific group. Usually you get a drop down selection so you can choose which task to execute. Since you have specified one of the tasks as default, the selection will be skipped and instead the default task is executed.
You can work around that by adding dependencies. Take the following example:
{
"version": "2.0.0",
"tasks": [
{
"label": "Echo 1",
"command": "echo",
"type": "shell",
"args": [ "echo1" ],
"group": {
"kind": "build",
"isDefault": true
},
"dependsOn":["Echo 2"]
},
{
"label": "Echo 2",
"type": "shell",
"command": "echo",
"args": [ "echo2" ],
"group": "build"
}
]
}
As Echo 1 depends on Echo 2, Echo 2 will be executed prior to executing Echo 1. Note that the definition is a list, so more than one task can be specified. In that case the tasks are executed in parallel.
In your case adding "dependsOn":["Compile/minify cms.scss"] to your main build task should execute both tasks.
You can use Compound Tasks.
The example below executes "Client Build" and "Server Build" tasks when "Build" task is called.
{
"version": "2.0.0",
"tasks": [
{
"label": "Client Build",
"command": "gulp",
"args": ["build"],
"options": {
"cwd": "${workspaceFolder}/client"
}
},
{
"label": "Server Build",
"command": "gulp",
"args": ["build"],
"options": {
"cwd": "${workspaceFolder}/server"
}
},
{
"label": "Build",
"dependsOn": ["Client Build", "Server Build"]
}
]
}
Add 'gulp-load-plugins' plugin in package.json
var gulpLoadPlugins = require('gulp-load-plugins'),
plugins = gulpLoadPlugins();

Double check your settings are enabled for Gulp auto-detection:
"gulp.autoDetect": "on"
I have been ploughing through the documentation of Visual Studio Code to figure out how to add multiple consecutive tasks to the tasks.json file.
The tasks array only allows for creating different arguments to the same command. In this example the command is echo.
{
"version": "0.1.0",
"command": "echo",
"isShellCommand": true,
"args": [],
"showOutput": "always",
"echoCommand": true,
"suppressTaskName": true,
"tasks": [
{
"taskName": "hello",
"args": ["Hello World"]
},
{
"taskName": "bye",
"args": ["Good Bye"]
}
]
}
Does tasks.json allow several tasks to be executed consecutively? For example, tsc followed by uglify?
The dependsOn feature was shipped in version 1.10.0. For example, I am using this to compile and run single file scripts in TypeScript:
{
"version": "2.0.0",
"tasks": [
{
"command": "tsc -p ${cwd}/2017-play",
"label": "tsc-compile",
"type": "shell"
},
{
"command": "node ${cwd}/2017-play/build/${fileBasenameNoExtension}.js",
"label": "node-exec",
"type": "shell",
"dependsOn": [
"tsc-compile"
],
"problemMatcher": []
}
]
}
Here is a working example that runs the tcs build and copies the source to another folder using a shell script.
This is based on various posts on StackOverflow and the documentation found here:
https://code.visualstudio.com/updates/v1_10#_more-work-on-terminal-runner
One could also make a tasks.json with two tasks with the second having a dependsOn on the first one as shown in Ben Creasy post, the two tasks would get executed when the second one is called. I needed to be able to execute one, the other or both. Many thanks to Ben, I had a hard time finding a solution before hitting this post.
BTW, when including a shell file, the commands are run with reference to the project folder, not the one where the script is located.
