Maven resources plugin does not honour maven.test.skip flag

Affected version

4.0.0-beta-2-SNAPSHOT

Bug description

The following integration test fails when Maven Resource Plugin 4.0.0-beta-2-SNAPSHOT is tested with Maven 4.0.0-rc-6:

• src/it/MRESOURCES-131 (GitHub issue [MRESOURCES-131] Maven resources plugin does not honour maven.test.skip flag #217)

This integration test has the following configuration in its pom.xml:

  <build>
    <pluginManagement>
      <plugins>
        <plugin>
          <artifactId>maven-resources-plugin</artifactId>
          <version>@project.version@</version>
          <configuration>
            <skip>true</skip>
          </configuration>
        </plugin>
      </plugins>
    </pluginManagement>
  </build>

The ResourcesMojo class has the following field:

    /**
     * You can skip the execution of the plugin if you need to. Its use is NOT RECOMMENDED, but quite convenient on
     * occasion.
     *
     * @since 3.0.0
     */
    @Parameter(property = "maven.resources.skip", defaultValue = "false")
    private boolean skip;

The TestResourcesMojo class has the following field:

    /**
     * Set this to 'true' to bypass copying of test resources.
     * Its use is NOT RECOMMENDED, but quite convenient on occasion.
     * @since 2.6
     */
    @Parameter(property = "maven.test.skip", defaultValue = "false")
    private boolean skip;

I verified in the debugger that the skip flag is true in ResourcesMojo but not in TestResourcesMojo.
