}

这显然是不赞成的，但是在这个上下文中，不赞成的消息对我来说没有意义。我现在应该如何设置这个值呢？

/**

     *
     * <strong>This method will be {@code @Deprecated} soon, please use {@link #getTestResults()} instead to access the new collection property.</strong>
     */
    public void setDestinationDir(File destinationDir) {
        DeprecationLogger.deprecateProperty(TestReport.class, "destinationDir").replaceWith("destinationDirectory")
            .willBeRemovedInGradle8()
            .withDslReference()
            .nagUser();
        getDestinationDirectory().set(destinationDir);
    }
