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 sy

Answer 1

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.

Answer 2

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.

Answer 3

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

Answer 4

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.

Answer 5

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'.

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
