I want to avoid duplicate code, so i am trying to load grunt task from Grunt file "a" and use them in gruntfile "b".
that means: i want to see all task of "a" in file "b" (but without code), just setup like a reference or template to another gruntfile.
here is grunt file "b":
module.exports = function (grunt) {
'use strict';
var karmaGrunt = './../../grunt',
abortHandler = function () {
var errors = grunt.fail.errorcount,
warnings = grunt.fail.warncount;
if (errors > 0 || warnings > 0) {
//run rocketlauncher python script and then stop the grunt runner.
grunt.task.run(["shell:rocketlauncher", "fatal"]);
}
},
fatal = function () {
// this function stops grunt and make the jenkins build red.
grunt.fail.fatal('failed');
};
require("grunt-load-gruntfile")(grunt);
// load grunt task from another file and add it.
grunt.loadGruntfile(karmaGrunt);
//grunt needs to continue on error or warnings, that's why we have to set the force property true
grunt.option('force', true);
grunt.initConfig({
shell: {
options: {
execOptions: {
cwd: '../scripts'
}
},
'rocketlauncher': {
command: './runRocketLauncher.sh'
}
}
});
grunt.loadNpmTasks('grunt-karma');
grunt.loadNpmTasks('grunt-shell');
grunt.registerTask('build-process', ['karma', 'abortHandler']);
grunt.registerTask('abortHandler', abortHandler);
grunt.registerTask('fatal', fatal);
}
here is file "a":
module.exports = function (grunt) {
"use strict";
var eConfig = '../e-specs/karma.config.js',
dConfig = '../d-specs/karma.config.js',
cConfig = '../c-specs/karma.config.js';
grunt.initConfig({
karma: {
options: {
reporters: ['progress', 'coverage', 'threshold']
},
c: {
configFile: cConfig
},
d: {
configFile: dConfig
},
e: {
configFile: eConfig
}
}
});
grunt.loadNpmTasks('grunt-karma');
};
my file b load the task "Karma" but if i run only the grunt file of a i have 3 nested task ("e","c","d") but if i load them from another file, the only task i can see is "karma"
the error is:
No "karma" targets found. Warning: Task "karma" failed. Used --force, continuing.
Done, but with warnings.
If i run the same task in file "a" directly the task is working like a charm.

There is a grunt plugin to load another Gruntfile: grunt-load-gruntfile
With this you can merge two Grunt configurations, including the defined tasks.
Here is an example:
./Gruntfile.js
:
module.exports = function (grunt) {
require("grunt-load-gruntfile")(grunt);
grunt.loadGruntfile("web"); //loads the Gruntfile from the folder web/
grunt.registerTask('showConfig', "shows the current config", function(){
console.log(JSON.stringify(grunt.config(), null, 2));
});
};
and the second Gruntfile in ./web/Gruntfile.js
.
module.exports = function (grunt) {
grunt.config("WebConfig", "Configuration from the Gruntfile in web/Gruntfile.js");
grunt.registerTask('server', "runs the server",function(){
console.log("just shows this message");
});
};
running grunt showConfig
executes the task from the first Gruntfile and displays the configuration, including the parameter defined in ./web/Gruntfile.js
.
running grunt server
executes the task from ./web/Gruntfile.js
.
