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

Solution 1:

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) {}

Solution 2:

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:

no instance(s) of type variable(s) V exist so that ExpectedCondition<> ...

method until in class org.openqa.selenium.support.ui.FluentWait cannot be applied to given types; required: java.util.function.Function found: org.openqa.selenium.support.ui.ExpectedCondition reason: cannot infer type-variable(s) V (argument mismatch; org.openqa.selenium.support.ui.ExpectedCondition cannot be converted to java.util.function.Function)

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