Use the following flags to skip non-essential steps during development and patching:

-DskipTests: Skips unit tests.
-Dcheckstyle.skip=true: Skips Checkstyle code analysis.
-Dpmd.skip=true: Skips PMD analysis.
-Dforbiddenapis.skip=true: Skips forbidden API checks.
-Dspotbugs.skip=true: Skips SpotBugs static analysis.
-Danimal.sniffer.skip=true: Skips API compatibility checks.
-Denforcer.skip=true: Skips Maven Enforcer rules.
-Djacoco.skip=true: Skips code coverage reporting.
-pl '!web-console': Excludes the web-console module (prevents OOM and save time).

To build only the necessary modules and their dependencies:

mvn clean package [skip-flags] -pl indexing-service -am

-am (also-make) ensures that all dependencies of the specified project are also built.

If Maven runs out of memory, you can increase the heap size:

export MAVEN_OPTS="-Xmx2048m"
