It is a good practice to always define a root project name. However, this change is specifically being made to address a build caching miss as a result of not having the root project name defined. The `aggregatedJavadoc` task takes in the root project name as an input. When executing the build from two uniquely named directories, we will see the second execution of `aggregatedJavadoc` will be re-executed due to computed build cache key being different. Here are the steps to reproduce the issue: 1. Remove the contents of the Gradle local build cache with `rm -rf ~/.gradle/caches/build-cache-1`. WARNING: This is a destructive action, consider renaming the directory instead if you need to preserve the local build cache. 2. Clone and execute the project with `git clone --depth 1 g...@github.com:apache/kafka.git first_build && (cd first_build && ./gradlew aggregatedJavadoc --build-cache)`. 3. Clone and execute the project again with `git clone --depth 1 g...@github.com:apache/kafka.git second_build && (cd second_build && ./gradlew aggregatedJavadoc --build-cache --scan)`. 4. Agree to the Gradle Terms of Service when prompted to publish a Build Scan. 5. We can see on the Performance > Task execution screen that [a cacheable task](https://scans.gradle.com/s/7bnq7gb4ykmdk/timeline?cacheability=cacheable&hide-timeline&outcome=success,failed&sort=longest) has been executed. We can click the Cacheable link to find [the culprit](https://scans.gradle.com/s/7bnq7gb4ykmdk/timeline?cacheability=cacheable&hide-timeline&outcome=success,failed&sort=longest#lhlgorbepbsx4). ### Committer Checklist (excluded from commit message) - [x] Verify design and implementation - [x] Verify test coverage and CI build status - [x] Verify documentation (including upgrade notes) -- This is an automated message from the Apache Git Service.
