Exception when trying to use PageFactory in selenium with Java

Question

I am trying to automate simple web application, for that, I am using Page Object Model Pattern, with Selenium and Java, My maven pom dependencies look like this:

<dependencies>
    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-firefox-driver</artifactId>
        <version>3.12.0</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/org.seleniumhq.selenium/selenium-java -->
    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>
        <version>3.14.0</version>
    </dependency>

    <dependency>
        <groupId>org.testng</groupId>
        <artifactId>testng</artifactId>
        <version>6.9.13.5</version>
    </dependency>

    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-ie-driver</artifactId>
        <version>3.0.0-beta4</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/log4j/log4j -->
    <dependency>
        <groupId>log4j</groupId>
        <artifactId>log4j</artifactId>
        <version>1.2.17</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/org.seleniumhq.selenium/selenium-chrome-driver -->
    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-chrome-driver</artifactId>
        <version>3.12.0</version>
    </dependency>

</dependencies>

My Page Object Class looks like this:

public class Page {
    public Page(WebDriver driver) {
        PageFactory.initElements(driver, this);
    }
    @FindBy(linkText = "Players")
    private WebElement playersLink;

    public boolean isPlayersLinkVisible(){
        return playersLink.isDisplayed();
    }
}

My test looks like this:

public class Test{
  @Test
  public void test(){
        WebDriver driver = new ChromeDriver();
        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
        driver.get(URL);
        Page page = new Page(driver);
        System.out.println(page.isPlayersLinkVisible());
  }
}

But I am getting this exception, and can't figure out why?

java.lang.NoClassDefFoundError: org/openqa/selenium/WrapsElement

I had this issue because the selenium support version was different than the other selenium libraries I was using. The issue is fixed when the same version is used for all selenium libraries including the selenium support library in pom.xml

Thank you for your help. I had the same issue and resolved by upgrading old libraries in classpath.

I figured that out, apparently there were incompatible dependencies, I removed unnecessary ones and left only the ones I need:

<dependencies>

    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>
        <version>3.14.0</version>
    </dependency>

    <dependency>
        <groupId>org.testng</groupId>
        <artifactId>testng</artifactId>
        <version>6.9.13.5</version>
    </dependency>

    <dependency>
        <groupId>log4j</groupId>
        <artifactId>log4j</artifactId>
        <version>1.2.17</version>
    </dependency>

</dependencies>
