At what step in the Maven build process do resources get into the target directory?

During the Maven build process, resources are copied to the target directory in the process-resources phase.

At this step, all files from the src/main/resources directory are copied to the target/classes directory, which is then used for packaging into the final artifact (e.g., JAR).

Thus, process-resources is a standard phase responsible for preparing resources for further building and packaging.
