Error: Could not find gradle wrapper within Androi

Question

I know there are lots of questions similiar to this one, but i couldn't find a solution for my problem in any of those. Besides, I'll provide details for my specific case.

I coded an Ionic project in Ubuntu 16.04 LTS, and now I have to build it for release. So I run the command:

cordova build --release android

And I'm shown the following error:

Error: Could not find gradle wrapper within Android SDK. Might need to update your Android SDK.
Looked here: /home/user/Android/Sdk/tools/templates/gradle/wrapper

• I don't have this templates/gradle/wrapper directory.
• My Android Studio is 2.3, the latest version for now
• Android SDK Platform-Tools 25.0.3
• Android SDK Tools 25.3.1
• All Android versions from 2.1 (Eclair) to 7.1.1 (Nougat)

After extensive research, I put all the Android Studio-related environment variables in the file /etc/environment. So now it looks like this:

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/game:/home/<user>/Android/Sdk:/home/<user>/Android/Sdk/tools:/home/<user>/Android/Sdk/platform-tools"

ANDROID_HOME=/home/<user>/Android/Sdk
export ANDROID_HOME

JAVA_HOME=/usr/lib/jvm/java-8-oracle
export JAVA_HOME

GRADLE_HOME=/opt/android-studio/gradle/gradle-3.2
export GRADLE_HOME

Now, for the sake of testing the environment variables, I run the following commands:

source /etc/environment
echo $PATH
echo $ANDROID_HOME
echo $JAVA_HOME
echo $GRADLE_HOME

And all the path variables are correctly displayed.

So, it looks like the environment variables are like they should be according to the various similar questions and in tutorials i've searched. Does anyone know what am I doing wrong? Why do I still get the Gradle Wrapper error?

Answer 1

This solved my problem.

I just downloaded https://dl.google.com/android/repository/tools_r25.2.5-macosx.zip214 and overwrite the tools folder at ~/Library/Android/sdk/tools

Answer 2

For anyone who is still having this issue, this worked for me:

    cordova platform update android@latest

then build and it will automatically download the newest gradle version and should work

Answer 3

Just recently, I also encountered similar problem, and after I did this, it works:

I edited the file in /etc/profile

sudo nano /etc/profile

export JAVA_HOME=/home/abdul/java/jdk1.8.0_131
export PATH=$PATH:$JAVA_HOME/bin

export ANDROID_HOME=/home/abdul/Android/Sdk
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/platform-tools

export GRADLE_ANDROID_HOME=/home/abdul/android-studio/gradle
export PATH=$PATH:$GRADLE_ANDROID_HOME/gradle-3.2/bin
export PATH=$PATH:$GRADLE_ANDROID_HOME/m2repository

Other info (just in case):

Not quite sure about m2repository part, in the first try it pass the grandle but there is another error (gradlew-command-failed-with-exit-code-

1. I check if in android studio the repository is active, and it's not active, I try to activate it, and when I try it again (Cordova build Android), it download a few other file, maybe from the repository? And then when I delete the path, it still works. (also thanks to Marcin Orlowski sample so then I can understand about export path better).

I use:

• Linux Mint Serena
• node : v6.10.3
• npm : 3.10.10
• Cordova : 7.0.0
• Android Studio : 2.3.1
• Android SDK platform-tools : 25.0.5
• Android SDK tools : 26.0.2

Hope it can help anyone who might have the same problem like mine and need this too.

Thanks

Edit 3:

Cordova Android 6.2.2 has been released and it's fully compatible with SDK tools 26.0.x and 25.3.1. Use this version:

cordova platform update android@6.2.2

or

cordova platform rm android
cordova platform add android@6.2.2

Edit 2:

There has been another Android SDK tools release (26.0.x) that is not fully compatible with cordova-android 6.2.1.

Edit: Cordova Android 6.2.1 has been released and it's now compatible with latest Android SDK.

You can update your current incompatible android platform with cordova platform update android@6.2.1

Or you can remove the existing platform and add the new one (will delete any manual change you did inside yourProject/platforms/android/ folder)

cordova platform rm android cordova platform add android@6.2.1

You have to specify the version because current CLI installs 6.1.x by default.

Old answer:

Sadly Android SDK tools 25.3.1 broke cordova-android 6.1.x

For those who don't want to downgrade the SDK tools, you can install cordova-android from github url as most of the problems are already fixed on master branch.

cordova platform add https://github.com/apache/cordova-android

Answer 5

On linux (Ubuntu in my case) just install gradle:

sudo apt-get install gradle

Edit: It seems as though ubuntu repo only has gradle 2.10, for newer versions: https://www.vultr.com/docs/how-to-install-gradle-on-ubuntu-16-10

Answer 6

(Basically what @user3464070 already said)

For Mac:

cd ~/Library/Android/sdk
# download latest tools
curl -O https://dl.google.com/android/repository/tools_r25.2.3-macosx.zip
# overwrite existing tools folder without prompting
unzip -o tools_r25.2.3-macosx.zip
# clean up
rm tools_r25.2.3-macosx.zip
