Gradle wrapper needs to be built. Try running gradle wrapper --gradle-version 2.13 Remember to change 2.13 to your gradle version number. After running this command, you should see new scripts added to your project folder. You should be able to run the wrapper with ./gradlew build to build your code. Please refer to this guid for more information https://spring.io/guides/gs/gradle/.

Running this bash command works for me by running chmod 755 gradlew as sometimes file properties changed upon moving from one OS to another (Windows, Linux and Mac).

Linux / MacOS

As noted in the comments, just running

./gradlew

worked for me. Adding the ./ tells it to look in the current directory since it isn't in the path.

Windows PowerShell

.\gradlew

I use intellj idea and in windows in terminal type: gradlew.bat run it is working for me.

From mac,

Nothing is working except the following command

chmod 777 gradlew Then

./gradlew

the same problem occurs to me... I check the file wrx permissions with:
$ls -l ./gradlew -> -rw-rw-r-- (no execute permission)

so I use command $chmod +x ./gradlew and this problem solved.

First thing is you need to run the gradle task that you mentioned for this wrapper. Ex : gradle wrapper After running this command, check your directory for gradlew and gradlew.bat files. gradlew is the shell script file & can be used in linux/Mac OS. gradlew.bat is the batch file for windows OS. Then run,

./gradlew build (linux/mac). It will work.

If the answer marked as correct does not work, it is because you need to identify yourself as a super user.

sudo gradle wrapper --gradle-version 2.13

It worked for me.

In addition to @suraghch

Linux / MacOS ./gradlew clean

Windows PowerShell .\gradlew clean

Windows cmd gradlew clean

If you are using mac, try giving root access to gradlew by doing

chmod +x ./gradlew

For Ubuntu(linux) users: doing "bash ./gradlew build " works but "./gradlew build " doesnot work.

For me the issue was it was on NTFS file system, linux does not let execute a script from NTFS. Try moving the code from NTFS to a linux partition. then ./gradlew build should work

Hi @Hayden Stites I faced the same issue, but after some tries I found it was happening because I was trying to create build in git bash , instead of CMD with admin access. If you create build with Command prompt run as administrator build will get create.

If you are using VS Code with flutter, you should find it in your app folder, under the android folder:

C:\myappFolder\android

You can run this in the terminal:

./gradlew signingReport

You must have the Gradle wrapper available locally before using gradlew. To construct that

gradle wrapper # --gradle-version v.xy

Optionally, pass the gradle version explicitly. This step produces the gradlew binary.And then you should be able to

./gradlew build

Instead of gradlew assembleRelease use ./gradlew assembleRelease

Issue: Couldn't find gradlew at path jenkins

In my case within jenkins CI for flutter project, I have to first run flutter build app command then it automatically generated gradlew file. And above issue resolved.

I put this command in my jenkins file:

flutter build apk

if you are trying to run this command for flutter app then goto android folder first by cd android and then use the command it should work. cd android > ./gradlew signingReport

I had to do dos2unix * in my current folder to make it work
