What is the Gradle wrapper and why should you use it?

The Gradle wrapper is a script that can be added to your Gradle project and used to execute your build. In this video we'll talk about the key advantages of the Gradle wrapper, such as not needing to have Gradle installed on your machine in order to execute your build. Plus we'll run through how to apply and use the wrapper in your own project.

In Gradle 7+ you can no longer run "gradle wrapper" in an empty directory. Please use "gradle init" instead for new projects and "gradle wrapper" within existing projects. Here's the breaking change docs.gradle.or...

Thank you Tom!

Nicely explained. Just one clarification required, in the last minute of the video around 7th min, you have explained if we use `./gradlew build` it will use version 6.2.2 as specified by project. But if I understood correct, it should be using gradle 6.2.1 version which is specified by project.

[@TomGregoryTech]

Hi Muhammad. In the video I run:
./gradlew wrapper --gradle-version 6.2.2
This means the version used by the gradlew script from that point on will be 6.2.2.

[@bojorquezja]

Tks for the information!

[@antonhen23]

Thanks a lot!

[@TomGregoryTech]

No probs! Hope it helped you understand the Gradle wrapper.

In gradle 7, I tried creating a empty folder to test out the wrapper. But looks like it is no more supported.
I get this below error
"$ gradle wrapper
FAILURE: Build failed with an exception.
* What went wrong:
Executing Gradle tasks as part of a build without a settings file is not supported."
using "gradle init" works.
Liked your video. thanks for this.

[@TomGregoryTech]

Hi Mahesh. Thanks for bringing this problem to my attention. It was introduced in Gradle 7+. The workaround is to use "gradle init" instead.
I created this issue in the Gradle GitHub repository github.com/gradle/gradle/issues/17625 and I'll add a note to this video so viewers are aware.

[@ruchiverma1279]

Hi, I saw one of your videos on Gradle and it's really great. I am a novice to Gradle and keen to follow further videos on your channel. I am looking for some pointers for one of the tasks assigned to me in my assignment. There is a maven plugin and i need to make that plugin to be used in the Gradle projects. Can you guide me on what should be my starting point?

[@TomGregoryTech]

Hi Ruchi. Are you doing a Maven > Gradle migration? It's likely there is a corresponding plugin in Gradle. Here are some pointers docs.gradle.org/current/userguide/migrating_from_maven.html#migmvn:common_plugins

[@boots_on_the_grounds_of_war]

Running "gradle init" automatically creates the gradle wrappers. I'm not sure if things have changed since this video, but I didn't need to call "gradle wrapper".

[@TomGregoryTech]

Hi. Just call the wrapper task when you need to update the Gradle version.

[@prabudhabharatbansode8023]

I had have changed the Gradle versions to many times to resolve this issue but still facing issue of deprecation in my local for Gradle version.
Compile time: "Deprecated Gradle features were used in this build, making it incompatible with Gradle 8.0."
Any idea to resolve this ?
Reply Thanks

[@TomGregoryTech]

Hi. This is just a warning to say that when Gradle 8 is released you'll have a problem updating. Run your build again with "--warning-mode=all" to get more details on the problems, to help you fix them.

[@milon27]

would you create a video ,
how android studio setting up a android project using Gradle. its a lot of files and configuration .very confusing
would glad if you create video on that
thank you.

I have Windows and installed the 'git bash' ... just being curious, what did you do to get the tree and cat commands available in the Git bash? I got for example 'bash: tree: command not found' , but for other commands such as `ls -als` it works fine. Thanks in advance for the support

[@TomGregoryTech]

Hi Manuel. "cat" comes by default with Git bash. You can access Windows tree command it Git bash using "cmd //c tree"

[@manueljordan317]

@@TomGregoryTech Oh my mistake, yes about cat command, thanks for the "cmd //c tree", covered here too: superuser.com/questions/531592/how-do-i-add-the-tree-command-to-git-bash-on-windows

qq - why doesnt "gradlew init" provide a 'java' option and only groovy and kotlin?
also, thanks for great vids!

[@TomGregoryTech]

Hey Willem. In gradle init select "2. application" for type of project then you will see the "Java" option. The Groovy vs. Kotlin option is for the Gradle build script itself.

[@PianoSurRia]

Nobody wondered why a gradle wrapper was created at all? Why is there no such thing in other instruments? Because the they have made so many incompatibilities and redundant features that they confused themselves and are tired of supporting them

please remove irritating sound in between all the time

Thanks for checking out the video Gaurav. If I could go back and remove the sound, I would :)
