Custom Plugin not included while compiling Android in TI 3.1.1.GA

When running the ti build -p iphone, it works like a charm but building for android it wont find the plugin.

I have added the plugin needed code in the plugins/closessimulator/1.0/hooks/lehook.js

and while trying to build android I get the :

[INFO] plugin=/Users/{{username}}/Library/Application Support/Titanium/plugins/closessimulator/1.0/plugin.py [ERROR] Build Failed (Missing plugin for closessimulator) [ERROR] Build process exited with code 1 [ERROR] Project failed to build after 1s 949ms

I did not added any python code.

my plugin code :

exports.cliVersion = '>=3.X';
 
exports.init = function (logger, config, cli, appc) {
 
    cli.addHook('build.pre.compile', function (build, finished) {
 
        if ( build.target=="simulator" && build.platformName=="iphone"){
            var sys = require('sys');
            var exec = require('child_process').exec;
            function puts(error, stdout, stderr) { sys.puts(stdout); }
            exec("osascript -e 'tell app \"iPhone Simulator\" to quit' &", puts);
        }
        // "build" arg contains the state of the build
 
        // note: "build" arg is null for "build.pre.construct" event
 
        finished(); // remember to call finished!
 
    });
 
};
