------------------------------------
Summary: Support Maven build and test using multiple cores (was: Support
build and test using multiple cores)
> Support Maven build and test using multiple cores
> -------------------------------------------------
>
> Key: CAMEL-24318
> URL: https://issues.apache.org/jira/browse/CAMEL-24318
> Project: Camel
> Issue Type: Task
> Components: build system
> Affects Versions: 4.21.0
> Reporter: Aurélien Pupier
> Priority: Major
>
> Currently, the build on CI is launched using a single Core. Using multiple
> cores should allow to drastically reduce the time.
> Locally tests (22 cores, 32Gb RAM, similar to Jenkins large machines):
> * -T1C for 642 modules, it took 40'
> * without, it is still running after 1h40 and it has built 484 modules so far
> Currently, the full compilation can fail when launched with -T1C
> [ERROR] Failed to execute goal
> org.apache.maven.plugins:maven-remote-resources-plugin:3.3.0:process
> (default) on project bundles-pom: Error loading supplemental data models:
> Could not find resource 'target/legal/legal.xml'. -> [Help 1]
> and we also have a lot of test failures.
> Some ideas:
> * to check also if we can do the pure compile in // with all threads and
> then launch tests as of now (1 threads used although 22 are available on
> blarge jenkins machines)
> * see if it works and improve things for sonar analysis (40' on CI), this is
> a separate command than the others
> * on GitHub there are already 2 phases but it is using mvnd; [it is taking
> around 18 minutes|https://github.com/apache/camel/actions/runs/30412528538/
> * evaluate with -T1C and more specific values, T1C might overload the
> Jenkins nodes. To check.
> * evaluate available merory too, most surefire tests are launch in forked
> process with 2G of memory, if too many are launched in // it might exaust.
> Maybe can use lower in general and tweak with highe rvalue only on modules
> whiich requires it
