If you see a warning message like `gpg: WARNING: This key is not certified with a trusted signature!`, you can locally sign the Gradle key after importing it.
This tells your GPG installation that you trust this key and will prevent the warning from appearing again.

To do this, run the following command:

```bash

        collector.setSource("pom.xml");
        collector.add(Problem.Severity.ERROR, "Error message", 10, 5, null);
        collector.add(Problem.Severity.WARNING, "Warning message", 15, 3, null);

        List<Problem> problems = collector.getProblems();
        assertEquals(2, problems.size(), "Should collect both problems");

        logger.error(getCurrentIndent() + ConsoleIcon.ERROR.getIcon(terminal) + " " + message);
    }

    /**
     * Logs a warning with a warning icon.
     */
    public void warning(String message) {
        logger.warn(getCurrentIndent() + ConsoleIcon.WARNING.getIcon(terminal) + " " + message);
    }

     */

    }

    /**
     * Logs a warning message without an associated exception.
     *
     * @param message the warning message to be logged
     */
    default void warn(@Nonnull String message) {
        log(Level.WARN, message);
    }
