Looking for ways to speed up your Gradle builds? Look into setting the following flag.

• -Dorg.gradle.configuration-cache.read-only=true

It took me a little bit of time to understand this setting and the benefits. This flag is really beneficial when you are NOT using the same static build agent each time. (e.g. GitHub Hosted Runners, AWS Code Build)

In a nut-shell, when running in normal mode, configuration cache entries are written to your project directories configuration-cache folder during the configuration phase. This is good for static build servers. No need to write to the configuration-cache folder when the build server changes each time.

Sample Code:

      - name: Build project (with read-only configuration cache)
        run: |
          ./gradlew build shadowJar \
            --no-daemon \
            -Dorg.gradle.configuration-cache.read-only=true
