VS Code tasks.json -- Tasks work individually, but not combined

This is driving me nuts (go nuts!). Build / run file is proper and fmt command is proper. But if I try to combine into one tasks file, it stops working.

These two work fine on their own and behave the way I want:

tasks.json

{
"version": "0.1.0",
"isShellCommand": true,
"showOutput": "always",
"command": "go",
"taskName": "build",
"args": [
"build",
"-o",
"${workspaceRoot}.exe",
"&&",
"${workspaceRoot}.exe"
],
"isBuildCommand": true
}


tasks.json

{
"version": "0.1.0",
"isShellCommand": true,
"showOutput": "always",
"command": "go",
"taskName": "fmt",
"args": [
"fmt",
"${file}"
],
"isBuildCommand": true
}


But combined into one file, it will not work:

tasks.json

{
"version": "0.1.0",
"isShellCommand": true,
"showOutput": "always",
"command": "go",
"tasks": [
{
"taskName": "build",
"args": [
"build",
"-o",
"${workspaceRoot}.exe",
"&&",
"${workspaceRoot}.exe"
],
"isBuildCommand": true
},
{
"taskName": "fmt",
"args": [
"fmt",
"${file}"
]
}
]
}


Error given on build:

can't load package: package build: cannot find package "build" in any of:
D:\dev\Go\src\build (from $GOROOT)
D:\dev\Gopher\src\build (from $GOPATH)
can't load package: package -o: cannot find package "-o" in any of:
D:\dev\Go\src\-o (from $GOROOT)
D:\dev\Gopher\src\-o (from $GOPATH)
can't load package: package d:/dev/Gopher/src/myproject.exe: cannot find package "d:/dev/Gopher/src/myproject.exe" in any of:
D:\dev\Go\src\d:\dev\Gopher\src\myproject.exe (from $GOROOT)
D:\dev\Gopher\src\d:\dev\Gopher\src\myproject.exe (from $GOPATH)


I can't seem to understand why it works one way, but not the other. The second method (for combined tasks) is outlined here: Define multiple tasks in VSCode




Answer: The problem lies with adding "build" or "fmt" as an args when it's already listed as a taskname. I did not know that's how taskname worked. Final working product which allows users to develop without worrying about stupid windows firewalls:

tasks.json (final & working thanks to @not-a-golfer)

{
"version": "0.1.0",
"isShellCommand": true,
"showOutput": "always",
"command": "go",
"echoCommand": true ,
"tasks": [
{
"taskName": "build",
"args": [
"-o",
"${workspaceRoot}.exe",
"&&",
"${workspaceRoot}.exe"
],
"isBuildCommand": true
},
{
"taskName": "fmt",
"args": [
"${file}"
]
}
]
}

Answer

The following seems to be working, but it appears that you can't chain the running with &&:

{
"version": "0.1.0",
"isShellCommand": true,
"showOutput": "always",
"command": "go",
"echoCommand": true ,
"tasks": [
    {
        "taskName": "build",
        "args": [
            "-x",
            "-o",
            "${workspaceRoot}.exe"
        ],
        "isBuildCommand": true
    },
    {
        "taskName": "fmt",
        "args": [
            "${file}"
        ]
    }
]
}
