/**
 * A destination to which characters can be written, such as a text file. Unlike a {@link Writer}, a
 * {@code CharSink} is not an open, stateful stream that can be written to and closed. Instead, it
 * is an immutable <i>supplier</i> of {@code Writer} instances.

    assertThat(pool.closeConnections(50L)).isEqualTo(100L)

     * @param message The message describing the problem, may be {@code null}.
     * @param severity The severity level of the problem, may be {@code null} to default to
     *            {@link SettingsProblem.Severity#ERROR}.
     * @param source A hint about the source of the problem like a file path, may be {@code null}.

 * A map from artifact name to a set of class name prefixes that should be kept.
 * Artifacts matched by this map will be minified to only contain the specified
 * classes and the classes they depend on. The classes are not relocated, they all
 * remain in their original namespace. This reduces the final Gradle distribution

   * first permutation will be in ascending order, and the last will be in descending order.
   *
   * <p>Elements that compare equal are considered equal and no new permutations are created by
   * swapping them.
   *
   * <p>An empty iterable has only one permutation, which is an empty list.
   *
   * @param elements the original iterable whose elements have to be permuted.

 *  * The client's handshake certificates must include a set of trusted root certificates. They will
 *    be used to authenticate the server's certificate chain. Typically this is a set of well-known
 *    root certificates that is distributed with the HTTP client or its platform. It may be
 *    augmented by certificates private to an organization or service.
