Summary: Investigate using develocity to improve james build
Key: JAMES-3978
URL: https://issues.apache.org/jira/browse/JAMES-3978
Project: James Server
Issue Type: Improvement
Components: Build System
Reporter: Jean Helou
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
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.
