我定义了一个gulpfile任务，它使用javascript文件运行节点：
var exec = require('child_process').exec;
gulp.task('node-run', function (cb) {
exec('node dest/index.js', function (err, stdout, stderr) {
console.log(stdout);
console.log(stderr);
cb(err);
});
})
但是，我想将文件名（dest / index.js）作为task.json中任务的参数传递，该任务代表VS Code中的选定文件。例如：
{
"version": "0.1.0",
"command": "gulp",
"isShellCommand": true,
"args": [
"--no-color"
],
"tasks": [
{
"taskName": "node-run",
"showOutput": "always",
"args": ["${file}"]
}
]
}
但是，当我尝试执行任务时，收到以下错误：
Using gulpfile gulpfile.js
Task '/Users/Tony/Source/HelloVsCode/.vscode/tasks.json' is not in your gulpfile
Please check the documentation for proper gulpfile formatting
所以我想知道是否可以传递＆＃34; $ {file}＆＃34; gulpfile任务的参数？
答案 0 :(得分：0)
{
"version": "0.1.0",
"command": "gulp",
"isShellCommand": true,
"args": [
"--no-color"
],
"tasks": [
{
"taskName": "${file}",
"showOutput": "always",
"args": ["node-run"]
}
]
}
{
"version": "0.1.0",
"command": "gulp",
"isShellCommand": true,
"args": [
"--no-color"
],
"tasks": [
{
"taskName": "--verbose",
"isBuildCommand": true,
"showOutput": "always",
"args": [
"vet"
],
"problemMatcher": [
"$jshint",
"$jshint-stylish"
]
},
{
"taskName": "vet",
"isTestCommand": true,
"showOutput": "always",
"args": [],
"problemMatcher": [
"$jshint",
"$jshint-stylish"
]
}
]
}
注意相同的两个任务vet但在一个实例中传递了一个arg --verbose，它需要反转才能由于某种原因正确执行。我仍然使用这个hack用于VSCode。我在v3.9.0，Node v0.12.7和Ubuntu GNU / Linux 12.04上运行VSCode v0.9.1，Gulp CLI和Local。* LTS。
