Answer 1

Got it,

Add the file location to environment variable PATH

C:\Users\user\AppData\Local\Android\Sdk\tools\templates\gradle\wrapper

I do not have templates/ directory in my tools/ directory. I have tried the other solution (of adding gradle installation path) but have no success. I am missing gradlew.bat – Spoonerism

However the gradle -v command works well, as I have added Gradle installation path to environment variable. I'm using Win 10. – Spoonerism

Answer 2

Another version of the @Kai Jie findings, that works for me.

Compiling previous answers I did the following to get Android SDK and gradle working (You need gradle working anyway to compile your Android project):

1. Prerequisites. You have gradle installed in the folders like I found on my computer. Please, check it:

   C:\Program Files\Android\Android Studio\gradle\gradle-X.X\
   

2. Set a new system variable (Control Panel\System and Security\System Advance system ->settings->environment variables-system variables). Do not forget to change a gradle version.

   GRADLE_HOME   C:\Program Files\Android\Android Studio\gradle\gradle-X.X\
   

3. Add the following path to system paths (Control Panel\System and Security\System Advance system ->settings->environment variables-system variables):

   %GRADLE_HOME%\bin
   

4. You might want to REBOOT your computer, to make sure, that the system sees the variables.

5. Check if gradle works properly with the terminal commands

   $ gradle -v

If the environment variables are set. I found that you need to actually start gradle. Then you can use the gradlew command.

If you are learning from Spring.io. Their site says to just run

./gradlew build && java -jar build/libs/gs-spring-boot-0.1.0.jar

That will fail unless you first run

gradle

Intellij had me in the correct directory so I just deleted

./

and run

gradlew build && java -jar build/libs/gs-spring-boot-0.1.0.jar

The app started right up.

Answer 4

if your gradlew.bat file is being generated but delete itself after a few second than it's a problem of your android studio . steps to follow : 1 . open your android studio and click on configure. 2. Go to setting there. 3.Click on Build,Execution,Deployment => Build Tools => Gradle. 4. check Gradle user home if it's pointing to .gradle file location or not .If it's not than give the correct path of .gradle file like this in my case C:/Users/Your_PC_Name/.gradle . 5. And than create new reactproject.

Answer 5

You probably have to do something like:

./gradlew assembleDebug

Answer 6

Add code below to the bottom of build.gradle file

task createWrapper(type: Wrapper) {
    gradleVersion = '4.9'
};

then run gradle createWrapper in terminal

This will generate gradlew.bat file and corrospondinf gradlew files

Bustup

Answer 7

in my case, I had a & sign in the name of the folder that I had put in the flutter project. removing it solved the problem for me.
