> Hello,
> A while ago I noticed [this
> announcement|https://news.apache.org/foundation/entry/the-apache-software-foundation-announces-gradle-as-a-platinum-targeted-sponsor]
> gradle becoming a platinum sponsor of the ASF.
> In particular the announcement was about gradle offering the develocity
> service to the ASF. It so happens that I investigated develocity as part of
> my day job, and while we can't afford it there it is definitely something we
> might leverage here !
> The tool is available at [https://ge.apache.org|https://ge.apache.org/]
> I want to investigate the following leads
>
> # local caching for builds enable reuse of tasks output to speed up repeated
> tasks
> # build scans to provide detailed build reports and individual build metrics
> # build metrics are collected across all build scans and allow to target
> objectively bad contributors to overall build time
> # enabling the remote build cache
> ** additionally improves both local and CI build times
> ** requires some attention to read/write permissions to avoid cache
> poisoning and supply chain attacks
> ** most likely requires a dedicated build cache node request to infra
> ** several projects already use it so it is a known unknown ( we know it can
> be done we don't yet know how)
> # leverage advanced test features of develocity unknown unknowns at least
> for me:D
> ## the tool collects tests metrics to pinpoint flaky tests enabling targeted
> fix efforts
> ## the tool claims to be able to do test avoidance and not rerun tests that
> are irrelevant to the changes
> ## the tool claims to be able to distribute test excecution accross
> dedicated test workers
> Since we use maven, we won't get the full benefits of the build cache (
> gradle has been pushing plugin authors to write build cache friendly code for
> a long time ) but it should improve the current situation quite a bit.
>
> Apache pulsar is also using develocity with maven:
> - develocity configuration
> [https://github.com/apache/pulsar/blob/master/.mvn/gradle-enterprise.xml]
> - infra wiki has infos on how to onboard
