Install Gradle on Amazon Linux and CentOS

### I assume you run the commands as root
gradle_version=2.6
wget -c http://services.gradle.org/distributions/gradle-${gradle_version}-all.zip
unzip  gradle-${gradle_version}-all.zip -d /opt
ln -s /opt/gradle-${gradle_version} /opt/gradle
printf "export GRADLE_HOME=/opt/gradle\nexport PATH=\$PATH:\$GRADLE_HOME/bin\n" > /etc/profile.d/gradle.sh
source /etc/profile.d/gradle.sh
# check installation
gradle -v

I am getting erro bash: gradle: command not found for gradle -v

make sure you run the . /etc/profile.d/gradle.sh script under the account you need to run gradle in.

When i try to set the paths i get
sudo printf "export GRADLE_HOME=/opt/gradle\nexport PATH=$PATH:$GRADLE_HOME/bin\n" > /etc/profile.d/gradle.sh
-bash: /etc/profile.d/gradle.sh: Permission denied

Even with sudo

I have the same problem, try this as follows:

1. sudo vim /etc/profile.d/gradle.sh
2. then, input manualy

• export GRADLE_HOME=/opt/gradle
• export PATH=$PATH:$GRADLE_HOME/bin

3. :wq
4. sh /etc/profile.d/gradle.sh
   it works for me

The point is to run this script, Not doing it manually

In order to load the env variables, I needed to log out and log in again.
After that gradle --version works successfully

As I am not much knowledgable about Linux so can anyone help me understand the purpose of using the command "export?. I have seen the same for installing ANT as well.

export GRADLE_HOME=/opt/gradle
export ANT_HOME=/opt/ant

I also checked in http://services.gradle.org/distributions/ where it shows the latest version of gradle is 5.6.2 so can I download this latest one along with the code that you have shared in this git?

I followed these steps but it doesnt show work for me:

1. wget -c http://services.gradle.org/distributions/gradle-5.6.2-src.zip-all.zip

2. unzip gradle-5.6.2-src.zip -d /opt

3. I verified that I these files under /opt/gradle then,
   [root@ip-xxx-xx-xx-xxx gradle]# ls -alh
   total 56K
   drwxr-xr-x 6 root root 228 Feb 1 1980 .
   drwxr-xr-x 5 root root 61 Sep 26 13:46 ..
   -rw-r--r-- 1 root root 13K Feb 1 1980 build.gradle.kts
   drwxr-xr-x 3 root root 101 Feb 1 1980 buildSrc
   drwxr-xr-x 3 root root 113 Feb 1 1980 config
   drwxr-xr-x 6 root root 225 Feb 1 1980 gradle
   -rw-r--r-- 1 root root 331 Feb 1 1980 gradle.properties
   -rwxr-xr-x 1 root root 5.9K Feb 1 1980 gradlew
   -rw-r--r-- 1 root root 2.9K Feb 1 1980 gradlew.bat
   -rw-r--r-- 1 root root 7.8K Feb 1 1980 released-versions.json
   -rw-r--r-- 1 root root 4.8K Feb 1 1980 settings.gradle.kts
   drwxr-xr-x 104 root root 4.0K Feb 1 1980 subprojects
   -rw-r--r-- 1 root root 6 Feb 1 1980 version.txt

4. ln -s /opt/gradle-5.6.2 /opt/gradle

5. sudo vi /etc/profile.d/gradle.sh
   export GRADLE_HOME=/opt/gradle
   export PATH=$PATH:$GRADLE_HOME/bin

6. Then I tried in both commands but none of them worked.
   sh /etc/profile.d/gradle.sh
   source /etc/profile.d/gradle.sh

[root@ip-xxx-xx-xx-xxx ~]# gradle -v
-bash: gradle: command not found
[root@ip-xxx-xx-xx-xxx ~]# gradle --version
-bash: gradle: command not found

Any help will be appreciated.
OS: AWS Linux 2

Its interesting that when I follow the same steps with a different version i.e. 5.6.2, it does not work.
http://services.gradle.org/distributions/gradle-5.6.2-src.zip-all.zip

However, if I try the same version as yours i.e. 2.6, it works fine.

Not sure what is so different during the configuration of these two versions. Anyone????

sudo mkdir /opt/gradle
wget -c https://services.gradle.org/distributions/gradle-4.2.1-bin.zip
sudo unzip -d /opt/gradle gradle-4.2.1-bin.zip
export PATH=$PATH:/opt/gradle/gradle-4.2.1/bin

gradle -v
