Error message if file not found

[featdd]

I miss some error or notification during the process if a js file from the sources was not found.

Are you sure you don't see any message?

I'm sure, always happens to me when I forgot to install bower components or something. I defined them as a source file in my grunt task but there is no notification of a non existing file. :-/

Please share a minimum test case and I'll try to have a look. On Feb 17, 2015 2:58 PM, "Daniel Dorndorf" [email protected] wrote:

for example I deleted the jquery folder in my bower_components, but when it runs the task it just don't show the missing file

task:

uglify: {
    dist: {
        files: {
            'Resources/Public/js/scripts.min.js': [
                'bower_components/jquery/dist/jquery.min.js',
                'Resources/Private/Assets/js/main.js'
            ]
        }
    }
},

See this solution https://github.com/gruntjs/grunt-contrib-concat/issues/57

Or this: https://gruntjs.com/configuring-tasks#custom-filter-function

module.exports = function(grunt) {
    function checkFile(filepath) {
        if (!fs.existsSync(filepath)) {
            grunt.fail.warn("file not found: " + filepath);
        }
        return true;
    }
{src: sources, dest: baseTarget + target, filter: checkFile}

@juliusza I tried this and the filter only seems to run against files that exist. This was with [email protected] and [email protected]
