DevOps / Gradle8 Interview Questions

What is the Gradle Wrapper?

The Gradle Wrapper (gradlew / gradlew.bat) is a small script, checked into the project's repository, that downloads and runs the exact Gradle version the project was built with — so nobody needs Gradle pre-installed, and everybody who checks out the project builds with an identical version automatically.

./gradlew build

Behind the two shell scripts sit a gradle-wrapper.properties file specifying the exact distribution URL/version and a small gradle-wrapper.jar bootstrap. The first time ./gradlew runs on a machine, it downloads the specified Gradle distribution into a local cache if it isn't already present, then delegates the actual build to it. This is why CI pipelines and onboarding docs almost always say "run ./gradlew," not "install Gradle first" — the wrapper removes an entire category of version-mismatch problems.

What problem does the Gradle Wrapper primarily solve?
What file specifies which Gradle distribution version the wrapper should download?
