### Odtwórz problem

W większości przypadków problem wynika z **autorskiego kodu** osoby pytającej.

Często pytający umieszczają tylko fragment kodu, niewystarczający do **odtworzenia problemu**.

        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");
        assertEquals(Problem.Severity.ERROR, problems.get(0).getSeverity(), "First problem should be ERROR");

     * @param severity The severity level of the problem, may be {@code null} to default to
     *            {@link org.apache.maven.building.Problem.Severity#ERROR}.
     * @param source A hint about the source of the problem like a file path, may be {@code null}.
     * @param lineNumber The one-based index of the line containing the problem or {@code -1} if unknown.

### Das Problem verstehen

* Stellen Sie zunächst sicher, dass Sie **das Problem verstehen**, welches der Pull Request zu lösen versucht. Möglicherweise gibt es eine längere Diskussion dazu in einer GitHub-Diskussion oder einem GitHub-Issue.

Here's what to keep in mind and how to review a pull request:

### Understand the problem { #understand-the-problem }

* First, make sure you **understand the problem** that the pull request is trying to solve. It might have a longer discussion in a GitHub Discussion or issue.

* There's also a good chance that the pull request is not actually needed because the problem can be solved in a **different way**. Then you can suggest or ask about that.
