closureCompiler task silently fails.

[ArthurianX]

I have this task:

`closureCompiler: {

        options: {

            // [REQUIRED] Path to closure compiler
            compilerFile: 'compiler.jar',
            //checkModified: true,

            compilerOpts: {
                compilation_level: 'ADVANCED_OPTIMIZATIONS',
                formatting:'PRETTY_PRINT',
                language_in: 'ECMASCRIPT5_STRICT',
                angular_pass: null,
                create_source_map: null,
                externs: ['externs/angular.js', 'externs/underscore.js'],
                //define: ["'goog.DEBUG=false'"],
                warning_level: 'verbose',
                jscomp_off: ['checkTypes', 'fileoverviewTags', 'missingProperties'],
                summary_detail_level: 3
                //output_wrapper: '"(function(){%output%}).call(this);"'
            },
            execOpts: {
                /**
                 * Set maxBuffer if you got message "Error: maxBuffer exceeded."
                 * Node default: 200*1024
                 */
                maxBuffer: 999999 * 1024
            },
            TieredCompilation: true // will use 'java -server -XX:+TieredCompilation -jar compiler.jar'
        },
        // any name that describes your task
        processJS: {
            src: '<%= compile_dir %>/assets/<%= pkg.name %>-<%= pkg.version %>-codebase-'+currTimeStamp+'.js',
            dest: '<%= compile_dir %>/assets/<%= pkg.name %>-<%= pkg.version %>-codebase-'+currTimeStamp+'.js'
        }
    }`

I have ironed out all the errors I was getting and now when I run the task it still fails, like this:

`Executing: java -server -XX:+TieredCompilation -jar "compiler.jar" --js compile/assets/xxx-7.0.0-codebase-1409837668761.js --js_output_file=compile/assets/xxx-7.0.0-codebase-1409837668761.js --compilation_level ADVANCED_OPTIMIZATIONS --formatting PRETTY_PRINT --language_in ECMASCRIPT5_STRICT --angular_pass --create_source_map --externs externs/angular.js --externs externs/underscore.js --warning_level verbose --jscomp_off checkTypes --jscomp_off fileoverviewTags --jscomp_off missingProperties --summary_detail_level 3

Error: Command failed: 0 error(s), 0 warning(s)
FAILED to run command for target: processJS
Warning: Task "closureCompiler:processJS" failed. Use --force to continue.`

If I force it, everything is ok, but that is not the solution here.

What could I be doing wrong? Or what is the module doing wrong? :D

Thanks!

@ArthurianX can you please try to successfully execute the compiler command on command line without using the grunt task? Copy paste it to an editor, try to take it apart (remove parts) until it starts working...

Then we can figure out what's wrong...

Hey Thanasis,

I tried that. 

Directly in the shell I get a message as a response: '0 warnings, 0 errors'.

As a wild guess or going on a limb I'd say that grunt doesn't understand that message as a success, not certain. 

I have the latest closure.jar, I'll try hat you said and then update the issue here. 

thanks !

@ArthurianX does this issue persist? Are there any more indications as to the source / cause?

Hello,

I fixed this issue long time ago, but I honestly don't remember what the
issue was, apparently the task was silently failing because of some errors
in the code, I solved them and it worked, I also added proper externs for
the libraries I was using, and it all ended up being ok.

Sorry for not stating the solution here, I was utterly swamped!
