It appears that Ubuntu doesn't have new versions of Gradle in their repositories for some reason. I need it for a project that will be build by Launchpad.

What should I do about this?

Gradle requires a Java JDK to be installed. Gradle requires a JDK 1.5 or higher. Gradle ships with its own Groovy library, therefore no Groovy needs to be installed. Any existing Groovy installation is ignored by Gradle.

Gradle uses whichever JDK it finds in your path (to check, use java -version). Alternatively, you can set the JAVA_HOME environment variable to point to the install directory of the desired JDK.

So make sure that you have Java JDK installed, then head to Gradle's Website to download Gradle, and any other info that you may need.

Or, just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:

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

Well I could use that on my local machine but would that work on Launchpad? How would I tell it to download Gradle before starting the build. – Marlinc Aug 3 '13 at 10:40
I don't think that you can do that. I think that you need to build locally, and then add to Launchpad. – Mitch Aug 3 '13 at 10:47
Why did you unaccept? :) – Mitch Sep 19 '13 at 18:47
Because that would not work on Launchpad. In Launchpad you're able to add a PPA for build dependencies. So I added it and specified it as a build dependency on my package. I've added that as a answer to this question so others can see it too. – Marlinc Sep 20 '13 at 5:49
where is gradle home after running this commands? – nazar_art Feb 3 '14 at 0:59
sudo add-apt-repository ppa:cwchien/gradle
sudo apt-get update

This is correct answer, but before make sudo apt-get install gradle, do:

sudo apt-cache search gradle

and next install latest version from new repo. In my case it:

sudo apt-get install gradle-1.9

it work's! (if you don't tell, what version you need, it install gradle(1.4) from main repo, and error will be with you...).

But I get a message: "gradle-1.9 is already the latest version". Hence it doesn't let me install gradle. – Igor G. Apr 7 '15 at 19:26
Thanks for posting right answer. :) – Anil Chahal Jul 7 '15 at 12:27

Apparently its possible to add a PPA as a dependency to a PPA and thus including Gradle.

gradlew, the Gradle Wrapper, seems to be the best method:

It is a script generated by Gradle which can automatically:

  • download a required Gradle version if missing
  • use it when required

You will then always use ./gradlew command from the root of the project instead of your system's gradle.

How to generate the wrapper is explained on the docs and at:
