grunt-contrib-compress throws 'No “compress” targets found' and does nothing

[mbielski]

Originally posted on SO (http://stackoverflow.com/questions/36561902/grunt-contrib-compress-throws-no-compress-targets-found-and-does-nothing) but after a week of very low views and no answers I'm posting it here in the hope that maybe it's a bug.

When the compress task is called the output is consistently the following error message:

$ grunt squeeze >> No "compress" targets found. Warning: Task "compress" failed. Use --force to continue.

Aborted due to warnings. Process finished with exit code 3

Config info:

compress:{
    main:{
        options:{
            mode:'gzip',
            level:2
        },
        files:[
            {expand:true, cwd:'E:/s3/', src:['**'], dest:'E:/gz/s3/'}
        ]
    }
}

Grunt task: grunt.registerTask('squeeze', ['compress']);

All folders are known to be present (they are able to be used by a different task just fine.) I've tried the path with both frontslash and backslash, but I get the same result. This is running on W10, Node 4.x, and current version of Grunt and grunt-contrib-compress (1.2.0).

Did you forget to load the task inside Gruntfile ? I mean adding this line to your Gruntfile as shown in README:

grunt.loadNpmTasks('grunt-contrib-compress');

[mbielski]

No, it's there. I'll admit that I did have to look at the project to make sure, but yes, it's there. That line is after the grunt.initConfig section, but I've never had troubles with that placement for other modules. And just to be thorough, I tried it with that line above the grunt.initConfig section, but still get the same results.

I can't reproduce your issue on win7 and Linux. Maybe you have done something wrong or something goes wrong during npm install. Can you show us the content of your Gruntfile.js ?

[mbielski]

The system in question is W10, upgraded from W7 Pro, which was upgraded from XP Pro. I'm not sure how I could do something wrong by typing

npm install grunt-contrib-compress

but I've managed to screw up simple things before so it's always best to check things. Therefore, and just to be thorough, I uninstalled and re-installed the module and still get the same results. The uninstall and install both ran fine, no errors or warnings. My Gruntfile.js is as follows:

'use strict';

module.exports = function (grunt) { // Load grunt tasks automatically var log = 'C:/Users/Michael/Desktop/BackupLog.txt'; require('load-grunt-tasks')(grunt); require('logfile-grunt')(grunt, { filePath: log});

// Define the configuration for all the tasks
grunt.initConfig({
    aws: grunt.file.readJSON('grunt-aws.json'),
    aws_s3:{
        options: {
            debug:false,
            region:'us-west-1',

            downloadConcurrency: 5, // 5 simultaneous downloads

            gzipRename: 'swap' // when uploading a gz file, swap the original extension with the .gz extension
        },

grunt.loadNpmTasks('grunt-aws-s3');
grunt.loadNpmTasks('grunt-open');
grunt.loadNpmTasks('grunt-contrib-compress');

grunt.registerTask('default', ['aws_s3:backup','open:log']);
grunt.registerTask('restore', ['aws_s3:restore']);
grunt.registerTask('squeeze', ['compress']);

};

Also, in case it helps, my package.json contains:

{ "name": "backup", "version": "0.0.0", "dependencies": {}, "devDependencies": { "grunt": "~0.4.1", "grunt-aws-s3":"~0.14", "grunt-contrib-compress":"~1.2", "load-grunt-tasks":"~3.4", "logfile-grunt":"~0.2", "grunt-open":"~0.2" }, "engines": { "node": ">=0.8.0" } }

Thanks very much for looking into this.

Why is compress under aws_s3? double check that

[mbielski]

BINGO!

(Insert bad words here)

Like I said, I've managed to screw up simple things before. Much thanks vladikoff. Please close this issue.
