Android Studio how to run gradle sync manually?

Question

I'm debugging Gradle issues in Android Studio and see references to "Run gradle sync", but I'm not sure how to run this command.

How do I run "Gradle sync" from Android studio or Mac terminal?

If you came here for the "...or Mac terminal" you are out of luck. None of these answers are about syncing Android Studio itself from command line. — tir38, Jul 19 '21 at 20:53

Android studio should have this button in the toolbar marked "Sync project with Gradle Files"

EDIT: I don't know when it was changed but it now looks like this:

EDIT: This is what it looks like on 3.3.1
OR by going to File -> Sync Project with Gradle Files from the menubar.

I don't see that button in the toolbar or File menu in Android Studio 4. – mahmood Aug 20 '20 at 07:06
I can confirm the sync button appears on the toolbar in Android Studio 4.0.1 – SolidCoder Jan 28 '21 at 10:21

Why this question has so many upvotes if it is not answering OP's question? – Yarh Aug 11 '21 at 15:03
Is there a command that does this function? Can I run `./gradlew `? – shadox Apr 09 '22 at 16:14

The real question is: why do the people in charge of Android Studio keep *changing* this functionality? It's clearly a case of fixing something that's not broken. – SMBiggs Jul 13 '22 at 15:20

WARNING: --recompile-scripts command has been deprecated since gradle's version 5.0. To check your gradle version, run gradle -v.

./gradlew --recompile-scripts

it will do a sync without building anything.

Alternatively, with command line in your root project

./gradlew build

It will sync and build your app, and take longer than just a Gradle sync

To see all available gradle task, use ./gradlew tasks

Yes but build does more right? What is the difference between sync and build? – JohnyTex Apr 03 '19 at 12:00
build is a very generic task. it's like using a sledgehammer to crack a nut. On Android projects, running the "build" task could take forever! – cesards Jul 20 '19 at 17:13

In Android Studio 3.3 it is here:

According to the answer https://stackoverflow.com/a/49576954/2914140 in Android Studio 3.1 it is here:

This command is moved to File > Sync Project with Gradle Files.

This option appears to no longer exist? https://i.imgur.com/cNFUoxB.png (screenshot just taken, in Android Studio 3.5.3) – Venryx May 22 '20 at 09:21
@Venryx, it is strange. I have 3.6.3 and this menu still exists (https://imgur.com/a/F8FCpvk). Anyway, it is better to use a button in the Toolbar. – CoolMind May 22 '20 at 09:38
It was apparently a problem with some AndroidStudio/Gradle files being outdated. After deleting them and reimporting the project, the option showed up again. – Venryx May 22 '20 at 09:41
@Venryx, thanks for the explanation! Sometimes custom buttons disappear from the Toolbar (and then appear again). – CoolMind May 22 '20 at 09:44

Keyboard shortcut lovers can add a shortcut for running gradle sync manually by going to File -> Settings -> Keymap -> Plugins -> Android Support -> Sync Project with gradle files (Right click on it to add keyboard shortcut) -> Apply -> OK and you are done. Gradle Sync keyboard shortcut Choose any convenient key as your gradle sync shortcut which doesnot conflict with any other shortcut key, (I have choosen Shift + 5 as my gradle sync key), so next when you want to run gradle sync manually just press this keyboard shortcut key.

I presume it is referring to Tools > Android > "Sync Project with Gradle Files" from the Android Studio main menu.

gradle --recompile-scripts

seems to do a sync without building anything. you can enable automatic building by

gradle --recompile-scripts --continuous

Please refer the docs for more info:

I think ./gradlew tasks is same with Android studio sync. Why? I will explain it.

I meet a problem when I test jacoco coverage report. When I run ./gradlew clean :Test:testDebugUnitTest in command line directly , error appear.

Error opening zip file or JAR manifest missing : build/tmp/expandedArchives/org.jacoco.agent-0.8.2.jar_5bdiis3s7lm1rcnv0gawjjfxc/jacocoagent.jar

However, if I click android studio sync firstly , it runs OK. Because the build/../jacocoagent.jar appear naturally. I dont know why, maybe there is bug in jacoco plugin. Unit I find running .gradlew tasks makes the jar appear as well. So I can get the same result in gralde script.

Besides, gradle --recompile-scripts does not work for the problem.

Hi Victor, I have a trouble may proof you wrong, Here is what I got, I set a configProductID=11111 from my gradle.properties, from my build.gradle, I add "resValue "string". If I do a build clean from ADT, the resource R.string.ProductID can be generated. Then I can do gradlew assembleDebug to build. Then I change my config name from "ProductID" to "myProductID", I will get error to do 'gradlew tasks', also I can't do 'gradlew clean', all of them just fail. I am still struggling. As ".\gradlew.bat --recompile-scripts " seems no longer exists? — yunfei, Jan 09 '20 at 08:23

From terminal:

gradle prepareKotlinBuildScriptModel

NOTE: you can see what android studio is doing by inspecting the "Build" tab. There will be difference windows inside there. One should be "Sync"

It does something, like downloading the gradle version, but when I open the project in Android Studio afterwards, it still needs to sync. – Martin Braun Jun 03 '23 at 16:26

I have a trouble may proof gradlew clean is not equal to ADT build clean. And Now I am struggling to get it fixed.

Here is what I got: I set a configProductID=11111 from my gradle.properties, from my build.gradle, I add

resValue "string", "ProductID", configProductID

If I do a build clean from ADT, the resource R.string.ProductID can be generated. Then I can do bellow command successfully.

gradlew assembleDebug

But, as I am trying to setup build server, I don't want help from ADT IDE, so I need to avoid using ADT build clean. Here comes my problem. Now I change my resource name from "ProductID" to "myProductID", I do:

gradlew clean

I get error

PS D:\work\wctposdemo> .\gradlew.bat clean

FAILURE: Build failed with an exception.

* Where:
Build file 'D:\work\wctposdemo\app\build.gradle'

* What went wrong:
Could not compile build file 'D:\work\wctposdemo\app\build.gradle'.
> startup failed:
  General error during semantic analysis: Unsupported class file major version 57

If I try with:

.\gradlew.bat --recompile-scripts

I just get error of

Unknown command-line option '--recompile-scripts'.

I've the same error-message some minutes ago: > Unsupported class file major version 57 The issue for me was, that gradle doesn't work with current openJdk13 on Linux (I use Manjaro... an Arch-Like Linux). So to fix this, I've done this: I've checked which Java version I've installed at my pc, and choosed the version 8: sudo archlinux-java stauts sudo archlinux-java set java-8-openjdk Maybe this helping you out, even If your system seems to be windows. So try another SDK Version. Maybe it also solve your issue. — suther, Jan 10 '20 at 10:18
Hi @suther, many thanks for your reply, I have find the root cause and fixed, I don't think it is because of JAVA version. But as I described "gradlew clean" is not equal to "ADT clean". My fix was simply do "gradlew :app:dependencies", this will generate resource IDs from gradle configuration files. — yunfei, Jan 12 '20 at 13:09

Anyone wants to use command line to sync projects with gradle files, please note:

Since Gradle 5.0,

The --recompile-scripts command-line option has been removed.
