2020 Update:

Chrome: v84

ChromeDriver: v83

JDK: OpenJDK 11 (LTS)

Use Paths class for platform-independent file separators.

@Test
public void doFileDownload() throws Throwable {
    // Since Java 7: Relative path from project root dir
    // Put in target dir to avoid committing downloaded files
    var downloadDir = Paths.get("target").toAbsolutePath().toString();

    var prefs = new HashMap();
    prefs.put("download.default_directory", downloadDir); // Bypass default download directory in Chrome
    prefs.put("safebrowsing.enabled", "false"); // Bypass warning message, keep file anyway (for .exe, .jar, etc.)
    var opts = new ChromeOptions();
    opts.setHeadless(true);
    opts.setExperimentalOption("prefs", prefs);

    var driver = new ChromeDriver(opts); // ChromeDriver binary is added to PATH env var
    driver.manage().timeouts().implicitlyWait(3, TimeUnit.SECONDS);
    driver.manage().window().maximize();
    driver.get("https://the-internet.herokuapp.com/download");

    var downloadLink = driver.findElement(By.cssSelector("a[href*='some-file.txt']"));
    var downloadHref = downloadLink.getAttribute("href").replace(":", "");
    var downloadFileName = Paths.get(downloadHref).getFileName().toString();
    downloadLink.click();

    // Wait download to finish for 60s
    var downloadFilePath = Paths.get(downloadDir, downloadFileName);
    new WebDriverWait(driver, 60).until(d -> downloadFilePath.toFile().exists());

    // Since Java 11: Read content of downloaded file
    var content = Files.readString(downloadFilePath);

    // Do tests with string content...
    log.info("Content={}", content);

    driver.quit();
}

Output:

Doing mvn clean prior to any run also takes care of having to override existing files.
