A Java implementation of undetected selenium from python library undetected-chromedriver and selenium-stealth.

UndetectedChromeDriver uses the Java Reflection API to access and modify private fields specifically on the following fields:

• org.openqa.selenium.chromium.ChromiumOptions args [Map<String, Object>]
• org.openqa.selenium.chromium.ChromiumOptions experimentalOptions [Map<String, Object>]
• org.openqa.selenium.MutableCapabilities caps [List<String>]

You can use SeleniumStealthOptions safely without reflection.

To use the library, you can clone the repository and just copy all the src code into your project.
If you plan on using selenium-stealth, make sure to include the JS files located at src/main/resources/selenium-stealth/*.js.
The library tries to find selenium-stealth JS in classpath:selenium-stealth/*.js. SeleniumStealth will fail (or work unexpectedly) if not included.

Make sure these dependencies are installed and up to date:

1. Selenium (org.seleniumhq.selenium:selenium-java)
2. Gson (com.google.code.gson:gson)
3. Slf4j-simple (org.slf4j:slf4j-simple)
   Slf4j-simple is used to log ChromeDriver downloads and errors for ChromeDriver downloads. If you do not want to use Slf4j-simple, you can remove the usage of it in me.bramar.undetectedselenium.DriverPatcher.
4. Lombok (org.projectlombok:lombok)

ChromeDrivers downloaded through undetected-selenium will be stored at the following locations.
Currently you cannot change this. But you may use your own chromedriver using UndetectedChromeDriver.driverExecutable(new File("path/to/chromedriver"))
Windows: Appdata/Roaming/java_undetected_chromedriver
Mac: Library/Application Support/java_undetected_chromedriver
Linux: .local/share/java_undetected_chromedriver
These are copied from undetected-chromedriver. Drivers are downloaded from:
CFT: https://storage.googleapis.com/chrome-for-testing-public
Legacy: https://chromedriver.storage.googleapis.com
