wait.until(ExpectedConditions) doesnt work any more in selenium

I had the same issue.

I fixed it by using the not deprecated .until() method of WebDriverWait and by adding the following to my maven pom.xml:

<dependency>
      <groupId>com.google.guava</groupId>
      <artifactId>guava</artifactId>
      <version>21.0</version>
</dependency>

Other than that, my code looks exactly like before.

To be more specific there are now two .until() methods.

The old one (which is deprecated):
public void until(final Predicate<T> isTrue) {}

And the new one:
public <V> V until(Function<? super T, V> isTrue) {}

You would need to add dependency:

<dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-support</artifactId>
        <version>3.0.1</version>
</dependency>

This is in order to make your code still work. Although ultimately the code would need to be rewritten not to use deprecated FluentWait.

Note if you are using Maven that order of the dependencies do matter.

For example:

public static void main(String[] args) {
    System.setProperty("webdriver.gecko.driver", "/Users/me/geckodriver");
    final WebDriver driver = new FirefoxDriver();
    driver.get("https://www.google.com");
    final WebDriverWait wait = new WebDriverWait(driver, 5);
    final By feelLuckyXpath = By.xpath("//div[@class='jsb']/center/input[@type='submit' and @name='btnI']");
    wait.until(ExpectedConditions.visibilityOfElementLocated(feelLuckyXpath)).click();
    driver.close();
}

this code works fine with the following maven dependencies:

<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-java</artifactId>
    <version>3.8.1</version>
</dependency>

<dependency>
    <groupId>com.google.api-client</groupId>
    <artifactId>google-api-client</artifactId>
    <version>1.22.0</version>
</dependency>

but it may fail with reordered one:

<dependency>
    <groupId>com.google.api-client</groupId>
    <artifactId>google-api-client</artifactId>
    <version>1.22.0</version>
</dependency>

<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-java</artifactId>
    <version>3.8.1</version>
</dependency>

In this case because the google-api-client contains:

<groupId>com.google.guava</groupId>
<artifactId>guava-jdk5</artifactId>

as dependency which shadows the guava lib in the selenium lib.

In this case the error is:
