Android Studio 1.0 build too slow

Question

I've updated Android Studio to 1.0 RC (both 1 and 2) from 0.9x and my project build time passed from 20 sec to around 90 sec.

Anyone is having the same problem?

UPDATE

Running the same task on terminal, I see that the "Resolving dependencies" step is taking most of the extra time.

UPDATE 2

Thanks to @bond, I've noticed that going offline lowers the build time to about 30 sec, so I tried to use mavenLocal() on the build.gradle, but no luck there either.

Top Level build.gradle:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        mavenLocal()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        mavenLocal()
        jcenter()
    }
}

Answer 1

In compiler settings (Android Studio -> Preferences -> Project settings[your project] -> Compiler (Gradle-based Android Projects)), type --offline in the "Command-line options" box.

from ~4 minutes to ~20 seconds.

Answer 2

I ended up building the first time online, and after that switching to offline mode

That lowered the time to ~14 secs.

My guess is that gradle is trying to resolve dependencies online ignoring my "mavenLocal()" (and all its variants)

Answer 3

For Newcomers, who can't find Gradle Offline settings (Android studio 1.5.1)
File -> Settings -> Build,execution, deployment -> Build tools -> Gradle
last checkbox (Offline work)

and thanks a lot guys - from like 10 mins to 30sec
