cordova Android requirements failed: Could not find an installed version of Gradle

Solution for linux with apt-get (eg.: Ubuntu, Debian)

I have quite similar problem. I obtained error:

Error: Could not find an installed version of Gradle either in Android Studio,
or on your system to install the gradle wrapper. Please include gradle 
in your path, or install Android Studi

but without Exception. I solved it on Ubuntu by

sudo apt-get install gradle

I found also commands that allows install newest version of gradle in Ubuntu. It works only when first command is executed before (probably some dependecies are incorrect).

sudo add-apt-repository ppa:cwchien/gradle
sudo apt-get update
sudo apt-get install gradle-ppa

If it does not work, try:

export PATH=$PATH:/opt/gradle/gradle-3.5/bin

Ionic Angular & Android Could not find an installed version of Gradle either in Android Studio, or on your system to install the gradle wrapper

Assuming ANDROID_HOME & ANDROID_SDK_ROOT are all set.

The problem is with jdk 16.
We have to uninstall jdk 16 and install jdk 8.

After that, add the jdk path into the environment variable.

• In Admin part, click new => name it "JAVA_HOME" and input the path.
• In System variable part, click new => name it "JAVA_HOME" and input the path.
• In System variable part, click on 'path' => click 'edit' => then add %JAVA_HOME%\bin

Then you might see some problem with the gradle.
So go to https://gradle.org/install/
Then follow the "Installing manually" section.

• Download gradle, which will be in zip file
• Create a folder called Gradle
• Extract gradle.zip into Gradle folder.

In System variable part, click on 'path' => click 'edit' => then add C:\Gradle\gradle-6.8.3\bin

Ionic_CordovaError: Could not find an installed version of Gradle either in Android Studio, or on your system to install the gradle wrapper

finally i got the solution of my own question.

If you have already installed Android Studio and set the Environment variable like,

ANDROID_HOME : /Users/prakash/Documents/adt-bundle-mac-x86_64-20140321/sdk

Then you need to download the gradle and include it into your path. Click the link below to get manual. https://gradle.org/install

Once download completed, follow the below steps:

Step-1: Goto your sdk path. here is my path /Users/prakash/Documents/adt-bundle-mac-x86_64-20140321/sdk/tools

Step-2: create a new folder named as "gradle" and open it.

Step-3: Unzip the gradle folder here which was downloaded earlier.

Step-4: Now open terminal and run your ionic project.

Cordova Build - Could not find an installed version of Gradle

I finally figured it out.

Some of the files in the project were locked, owned by root. When I used just

cordova build android

an error message popped up saying that some file can't be read.

Therefore, when building, I used

sudo cordova build android.

That helped me to get rid of the permission problem but it also was the actual cause of the problem with Gradle...

...when a command is run with sudo the $PATH variable used is different (restricted). In my case, this is the value that was used when building without sudo:

/home/viktor/.sdkman/candidates/gradle/current/bin:/home/viktor/bin:/home/viktor/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/viktor/Android/Sdk/tools:/home/viktor/Android/Sdk/tools/bin:/home/viktor/Android/Sdk/platform-tools:/snap/bin

And this is $PATH with sudo:

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin

As you may see, the latter is missing the path to Gradle.

So, the solution here was to chmod and chown the project files and build without sudo just using

cordova build android.
