Maven Core Extensions Reference

  Maven core provides default {{{./extension.html}extensions}} as defined in <<</META-INF/maven/extension.xml>>>:

 * {{{./cli.html}CLI options}},

 * {{{./logging.html}logging API}}.

 * since 3.3.1 (see {{{/docs/3.3.1/release-notes.html#Core_Extensions}3.3.1 release notes}} for more details),
   per project settings can be defined by files in <<<.mvn/>>> directory:

   * <<<.mvn/jvm.config>>> containing jvm options,

   * <<<.mvn/maven.config>>> containing Maven command-line parameter,

 * (i.e. the <i>main</i> artifact) or the ones that will be used when building <i>tests</i>).
 * <p>
 * This extensible enum has two defined values, {@link #MAIN} and {@link #TEST},
 * but can be extended by registering a {@code org.apache.maven.api.spi.ProjectScopeProvider}.
 * <p>
