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

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.

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:

https://docs.gradle.org/current/userguide/gradle_command_line.html

Shortcut (Ubuntu, Windows):

Ctrl + F5

Will sync the project with Gradle files.

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.

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'.

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.

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"
