Gradle Build taking too long too complete

My gradle build is taking over 9 minutes to complete.
It was taking about less than a minute before which was ok. I dont know what went wrong.
I have tried a lot of adjustments and recommendations.
Gradle 4.4
my project level gradle is as follows
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.3'
classpath 'com.google.gms:google-services:3.3.1'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}

BUILD SUCCESSFUL in 9m 44s
26 actionable tasks: 24 executed, 2 up-to-date
My gradle sync also takes over 15 minutes to complete.
All the while i have another project in android studio that runs normally and takes significantly less time to sync and build.

So the problem was a bunch of viruses and malware on my system. After running a boot time scan on my system i ran the build and now its back to taking a minute to run.

Gradle exists with non-zero value

I'm working on an Adnroid app that was imported. The imported app used an old version of Gradle so I'm trying to sync it to the new ones (it used Gradle 19 I think). I'm unable to use Gradle 24 b/c there are symbol class finders that can't be found, so I'm just trying to get this working with 21, but it still won't work. Can anyone help?
Here is my outer .build file:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {

You're using gradle plugin 2.1.3 which according to documentation needs the following as must have dependencies.
Android Plugin for Gradle, Revision 2.1.3 (August 2016)
Dependencies:
Gradle 2.14.1 or higher.
Build Tools 23.0.2 or higher.
This update adds compatibility with Gradle 2.14.1, which includes performance improvements, new features, and an important security fix.
For more details, see the Gradle release notes.
whereas your build tool version currently set as buildToolsVersion "21.0.0".
Change the build tool version to 23.0.2, update the support and appcompat dependencies accordingly and sync again.

Android Studio proguardRelease FAILED due empty output jar library

I have imported a project from Eclipse into Android Studio 1.0.1 that consists in an Android Library Project (RuletaAfortunadaCore) and an Android Project (RuletaAfortunada), also have some third parties library dependencies. During the import everything seemed fine, but now when I try to build it I get this error message from Gradle:

The contents of the build.gradle file for such library project:
apply plugin: 'com.android.library'

defaultConfig {

}

compile 'com.google.android.gms:play-services:+'
compile files('libs/chartboost.jar')
compile files('libs/mint-4.0.7.jar')
}
UPDATE: I have realized that the Android Library Project named RuletaAfortunadaCore can be build as an standalone project or made as a module without problems at all. It only fails to build when building the whole RuletaAfortunada Android Project that uses it.
The build.gradle file for such Android Project is the default one created by Android Studio, I think, so has nothing interesting inside. Anyway, here it is, just in case:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.0.0'
}
}
allprojects {
repositories {
jcenter()
}
}
This is the settings.gradle:
include ':facebookSDK'
include ':ruletaAfortunadaCore'
include ':ruletaAfortunada'
And finally, just to have all of them, this is the facebookSDK module build.gradle:
apply plugin: 'com.android.library'
android {
compileSdkVersion 9
buildToolsVersion "21.1.2"
defaultConfig {
minSdkVersion 9
targetSdkVersion 9
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
dependencies {
compile 'com.android.support:support-v4:18.0.0'
compile files('libs/bolts-android-1.1.2.jar')
}

As suggested by one guy which answer seem to have vanished now :-?, the solution for me has been to set minifyEnabled to false in the build.gradle of my Library Project. As far as I have it set as true for the Android Project itself, proguard will be executed anyway and the error have disappeared.

I've found some useful info here: http://tools.android.com/tech-docs/new-build-system/migrating-to-1-0-0
One notable difference is that runProguard was changed to minifyEnabled.
However, after completing the steps from this migration topic, I still run into the same build error.

This Question is old but it may be useful for new programmers of Android Studio ,
So this error in my case solved by cleaning project from Build Menu.

I'm not sure if you post all error's text, in my case in the end will be very useful information to fix this trouble. Maybe in your case trouble is the same.
So, in my case was trouble with dependecies.
In my app module in build.grale I used other dependencies for support.v4
In your case: compile 'com.android.support:support-v4:19.1.0'
Facebook SDK used jar, so, support.v4 was added as jar.
To fix this, just remove jar, and add to your Facebook build.gradle file the same line to import support library as on your main app module.
Hope, this will help you.

I faced same issue today
This is a bug in dex merger when the dex files that are being merged have more than 65536 methods (or strings). We can fix this by adding
dexOptions {
jumboMode = true
}
In the gradle file. Don’t forget to add this all sub projects too else it may not work.

I faced this problem in ubuntu 16.04 and came up with a simple solution:
Type sudo nautilus in terminal.
Now go to the root directory and recursively change permissions to Read and Write and Create and Delete files. You will be able to do that by the option Change permissions for enclosed files.

How to reference system ProGuard binary in build.gradle?

I noticed that running gradle assembleRelease calls upon an outdated ProGuard version as can be seen from the shell output:
$ gradle assembleRelease
Relying on packaging to define the extension of the main artifact has been \
deprecated and is scheduled to be removed in Gradle 2.0

Total time: 15.703 secs
I use the following configuration in my build.gradle:
buildscript {

}
}
apply plugin: 'android'

compile 'com.android.support:support-v4:19.0.0'
compile 'com.google.android.gms:play-services:3.1.36'
}
How can I point gradle to a newer version of ProGuard which might be available from the PATH, e.g. /usr/local/bin/proguard?
An alternative solution is to reference the desired version as follows:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.6.+'
classpath 'net.sf.proguard:proguard-gradle:4.10'
}
}
...
What is your setup?

The official Proguard doc shows how you can point to proguard in the build.gradle. See here
As per the Proguard manual you can do the below to point to a proguard binary,
buildscript {
repositories {
flatDir dirs: '/usr/local/java/proguard/lib'
}
dependencies {
classpath ':proguard'
}
}
I think this might cause problems with the proguard version that comes shipped with the android SDK. Not tried yet!!
