Can't run ndk-build on Android studio from gradle on osx yosemite

I am trying to run ndk-build from my build.gradle in an Android Studio 1.0 project on MAC OSX Yosemite.

task ndkBuild(type: Exec) {
    commandLine 'ndk-build', '-C', file('src/main').absolutePath

}

I have specified the ndk-dir in the local.properties file but I am getting this error

A problem occurred starting process 'command 'ndk-build'

If I run the gradle script from command line like this everything successfully builds

./gradlew :myproject:assembleDebug

So for some reason the IDE is unable to call ndk-build. I enabled some debug info in Android studio and I have the following error 

Caused by: java.io.IOException: error=2, No such file or directory

So the IDE cannot find the ndk-build exe however running from the terminal inside the IDE the ndk-build exe can be found.

Thanks

EDIT

You can now retrieve the path like this :

android.ndkDirectory.getAbsolutePath()

I updated the sample below.

As you said in the comments, commandLine requires the path of ndk-build program to make it work. Here is a way to retrieve the ndk path in build.gradle :

// call regular ndk-build script from app directory  
task ndkBuild(type: Exec) {
        def ndkDir = android.ndkDirectory.getAbsolutePath()

        commandLine ndkDir + "/ndk-build", '-C', file('src/main').absolutePath
    }

You will have a "cannot infer argument type" lint warning, You can safely ignore this warning. Add // noinspection GroovyAssignabilityCheck to get rid of it.

This was tested with gradle 1.2.3
