Android Studio how to run gradle sync manually?

问题

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?

回答1:

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.

回答2:

./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

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.

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.

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.

回答6:

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.
