	// task 可以有多个，定义不同的 taskName 和 args就行
	"tasks": [
		{
			"taskName": "check widget" , // 写task 名字
			
			// 这里填写 path, 使用 node-glob 的match方式， 
			// **/* 代表当前目录 和子目录 下面所有的文件
			// node-glob 也可以 match 更复杂的
			// 比如 不检查script下 test文件夹 和 所有 test/spec 文件, 可以写：
			// script/!(test)/**/!(*_test.js|*_spec.js)'
			// 更多 参考  https://github.com/isaacs/node-glob
			"args": ["**/*"], 
			
			// Make this the default build command.
			"isBuildCommand": true,
			// Show the output window only if unrecognized errors occur.
			"showOutput": "always",
			
			"problemMatcher": {
				// The problem is owned by the typescript language service. Ensure that the problems
				// are merged with problems produced by Visual Studio's language service.
				"owner": "javascript",
				// The file name for reported problems is relative to the current working directory.
				"fileLocation": ["relative", "${cwd}"],
				// The actual pattern to match problems in the output.
				"pattern": [
					{
			           "regexp": "^fecs\\s+?INFO\\s(.+?)\\s.+messages\\)$", //regex 检测文件名
			           "file": 1
			        },
					{
