Stuck with Gradle Build Running

Question

While trying to build my Application on Android Studio 2.1 (On Ubuntu 16.04), it gets stuck on the below note:

Executing tasks: [:app:generateDebugSources, :app:mockableAndroidJar, :app:prepareDebugUnitTestDependencies, :app:generateDebugAndroidTestSources]

Can anybody please help me out.

while my problem wasn't exactly the same (i had an endless "Starting gradle daemon..." loop), [this](https://stackoverflow.com/a/64844390/3438172) fixed it for me. — Ace, Nov 15 '20 at 12:34

Actually it is not stuck. It takes more time to build. I have got almost 3 solutions that can fix the issue.

Solution-1:

Following the steps will make it 10 times faster and reduce build time 90%

First create a file named gradle.properties in the following directory:

/home/<username>/.gradle/ (Linux)
/Users/<username>/.gradle/ (Mac)
C:\Users\<username>\.gradle (Windows)

Add this line to the file:

org.gradle.daemon=true

org.gradle.parallel=true

Solution-2:

If Android Studio has a proxy server setting and can't reach the server then it takes a long time to build, probably its trying to reach the proxy server and waiting for a timeout. When I removed the proxy server setting its working fine.

In Android Studio go to File -> Settings -> Build, Execution, Deployment -> Build Tools -> Gradle

Check the 'Offline work' under 'Global Gradle settings'

It will reduce 90% gradle build time.

Solution-3

If you are using Google Play services, make sure you aren't using this in your Gradle build script:

compile 'com.google.android.gms:play-services:8.3.0'

Only use those Google APIs that your app is really using. If all you are using is Google Maps, you would use this:

com.google.android.gms:play-services-maps:8.3.0

When I did this, my compile time went from over 2 minutes to around 25 seconds. For a list of the Google apis that you can selectively compile against, see:

https://developers.google.com/android/guides/setup

Solution#4:

Arun George has commented the following solution.

the issue was due to certain 32 bit libraries missing. Had to do sudo apt-get install lib32z1. Adding to gradle.properties helped reduce the build time.

I think, the issue was due to certain 32 bit libraries missing. Had to do `sudo apt-get install lib32z1`. Adding to gradle.properties helped reduce the build time. Thanks:) — Arun George, May 08 '16 at 18:45
org.gradle.parallel=true should be used only with decoupled projects (IE: project that don't share objects). You can read more here: https://docs.gradle.org/current/userguide/multi_project_builds.html#sec:decoupled_projects — qwlice, Sep 27 '16 at 07:54

In Solution-1 is this a text file that you save as "gradle.properties"? — 101is5, Dec 08 '21 at 18:32

Changing buildToolsVersion was the solution for me.

This is the real solution. And sometimes the problem isn't caught by the warnings we so often see in the build.gradle file. Thanks! – SMBiggs Oct 06 '20 at 19:24
Elaborating: click the Project tab (upper-left corner)> right-click the "app" folder> click "Open Module Settings" > Modules > Properties > Select a version for "Compile SDK Version" and a version for "Build Tools Version" . Source: https://www.py4u.net/discuss/646549 Anyone tried selecting a version only for "Build Tools Version"? – 101is5 Dec 08 '21 at 18:15

The issue is that the project isn't synced with the gradle files. The resolution I did was go to File > Sync Project with Gradle Files and it was able to sync.

For my case I had to install gcc-multilib

$ sudo apt-get install gcc-multilib

Check the Gradle Console at the bottom right as it has more output than the Event log.

You're probably behind the proxy, you might have recently changed your password or something has changed. Go to

/home/<username>/.gradle/ (Linux)
/Users/<username>/.gradle/ (Mac)
C:\Users\<username>\.gradle (Windows)

in gradle.properties file, delete/ change proxy settings. They are different to your android studio proxy settings.

Had the same issue, gradle used to take an hour to build. After I deleted proxy settings from gragle.properties file, it now takes couple seconds.

This worked for me. It turns out that even though I set the proxy to No Proxy in Android Studio, the gradle.proerties file still contains Proxy entries. – F0r3v3r-A-N00b Jan 04 '20 at 14:39
I can't find gradle.properties. Is it supposed to be in the .gradle folder, inside any subfolder or do I have to create it? If I have to create it, how can I do it? – 101is5 Dec 08 '21 at 19:05

Adding more to @SkyWalker's answer:

Also check if you have the latest version of gradle. Updating gradle plug-in to the latest version could help.

Note: I have a similar setup(Android Studio 2.1 on Ubuntu 16.04), and I had a similar problem. Updating gradle to the latest version solved the problem for me.

Resolution for Gradle stuck using Android Studio version 4.2.2:

When the resources are downloaded successfully the Android Studio should be restarted with "Invalidate cache and restart" and offline Gradle mode should be activated before platform-tools indexing.
