错误：ENOENT，没有这样的文件或目录'empty：'

Question

requirejs: {
        compile: {
            options: {
                baseUrl: ".",
                name: "main",
                out: "main-built.js",
                paths: {
                    requireLib: "lib/require",
                    "buildinfo": "empty:",
                    "servlets/rpc/clientInit": "empty:",
                },
                mainConfigFile: "main.js",
                excludeShallow: ["servlets/rpc/clientInit", "buildinfo"],
                findNestedDependencies: true
            },
            optimize: "uglify2"
        }
    }

任何想法为什么？ buildinfo在运行时作为文本模块加载，无需在构建时添加它。

我正在使用grunt 0.4.4：

我的错误信息是：

>> Error: Error: Loader plugin did not call the load callback in the build:
>> text:
>>   text!buildinfo: Error: ENOENT, no such file or directory 'empty:'
>> Module loading did not complete for: main, sys/pageLife, sys/sammy.routing,   modules/settings/about
