NoSuchMethodError: org.openqa.selenium.support.ui.WebDriverWait.until
I think your problem is in this line of code
WebElement element=wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("dnn_dnnUser_enhancedRegisterLink")));As Wait.until is used to tell your web driver to wait until a certain action to occur which is visibility of The element located by ID = "dnn_dnnUser_enhancedRegisterLink" in your case but this method Doesn't return a web element object so you can't use it to define a web element
Instead you just need to write :
wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("dnn_dnnUser_enhancedRegisterLink")));
Selenium 3.1.0 onwards needs guava 21 for the wait.until method.Try adding this to your pom, preferable near the top in case another dependency is importing and older version of guava:
<dependency> <groupId>com.google.guava</groupId> <artifactId>guava</artifactId> <version>21.0</version></dependency>
