Answer 1

I'm using Linux Fedora 30 and my solution was this.

• First installing Gradle from the official page

• Once downloaded I unzip the file inside my sdk/tools path in my case is this /home/JCODE07/Android/sdk/tools/gradle

• The last step Open the .bashrc and added the path of Gradle to my PATH VARIABLE.

export PATH=$PATH:"/home/JCODE07/Android/sdk/platform-tools":"/home/JCODE07/Android/sdk/tools":"/home/JCODE07/Android/sdk/tools/gradle/bin"

I hope this works for you :)

How to install gradle in mac

1. Open terminal in Mac
2. Check whether brew is installed or not, just write brew if it is installed then write

brew install gradle

3. If ,it is not installed, install it and write this below line in terminal

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

4. Now gradle will be install
5. Now may be it will give an error

/Users/Desktop/project-name/platforms/android/gradlew: Command failed with exit code EACCES

6. Next step will be

sudo chmod 777 /Applications/Android\ Studio.app/Contents/gradle/gradle-4.10.1/bin/

sudo chmod 777 /Users/xyz/Desktop/project-name/platforms/android/gradlew

Happy Setting!! Hola!! This will work.

Answer 3

For Linux: Include the downloaded gradle path

Get your android sdk path... find it in .bashrc at the bottom: ANDROID_HOME=$HOME/Android/Sdk

$ mkdir $HOME/Android/Sdk/gradle

Unzip the gradle folder(that was downloaded earlier) here.

if Gradle was downloaded by SDKMAN, it will save it in $HOME/.sdkman/archives

$ unzip $HOME/.sdkman/archives/*.zip -d $HOME/Android/Sdk/gradle

set the path in .bashrc: for me the Sdk path is:

$ANDROID_HOME == $HOME/Android/Sdk

So you need to do...

export PATH=${PATH}:$ANDROID_HOME/gradle/gradle-5.1.1/bin

$ source1

$ cordova build

Answer 4

What worked for me was setting the bin folder inside the gradle folder into the PATH environment variable. So apart from all the steps listed above by @pb123 , additionally I had to set the PATH environment variable to include the gradle bin path. Using the example from his post:

export PATH=${PATH}:$ANDROID_HOME/tools/gradle/bin

You can set it in your ~/.bash_profile, so it becomes available across sessions.

Answer 5

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.
