java.lang.NoClassDefFoundError: org/openqa/selenium/WrapsElement error executing Selenium based mvn test

Question

So I am trying to run tests using mvn test -P and it is giving me java.lang.NoClassDefFoundError: org/openqa/selenium/WrapsElement when I run it from the cmd although it is working fine from within eclipse itself.

I have my pages classes src/main/java and my tests in src/test/java, I just can't get why it would work perfectly fine from eclipse but not from the command prompt. I assume it has something to do with the pom.xml but I am not sure

Here is my pom.xml:

Add below dependency to pom.xml file. It worked for me.

<dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-api</artifactId>
        <version>3.141.59</version>
    </dependency>

NoClassDefFoundError

NoClassDefFoundError in Java occurs when Java Virtual Machine is not able to find a particular class at runtime which was available at compile time. For example, if we have resolved a method call from a class or accessing any static member of a Class and that Class is not available during run-time then JVM will throw NoClassDefFoundError.

This error message...

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

...implies that Selenium is trying to resolve the particular class at runtime from org/openqa/selenium/WrapsElement which is no more available.

What went wrong :

As per Installing Selenium libraries - Java installation of Selenium libraries for Java is done using maven adding the following selenium-java dependency in your project pom.xml:

<dependency>
  <groupId>org.seleniumhq.selenium</groupId>
  <artifactId>selenium-java</artifactId>
  <version>3.X</version>
</dependency>

You seem to have used:

<!-- https://mvnrepository.com/artifact/org.seleniumhq.selenium/selenium-java -->
<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-java</artifactId>
    <version>3.141.59</version>
</dependency>

which should be sufficient to execute your tests.

So, the other dependency for <artifactId>selenium-common</artifactId> seems unnecessary which is of (Jan 01, 2011) and is as follows:

<!-- https://mvnrepository.com/artifact/org.seleniumhq.selenium/selenium-common -->
<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-common</artifactId>
    <version>2.0b1</version>
</dependency>

Solution :

Perform the following steps:

Remome the unwanted additional dependency of <artifactId>selenium-common</artifactId>
Do:
- maven clean
- maven install
- maven test

Thanks for your answer. When I did that it gave me a compilation failure and class file for org.openqa.selenium.WrapsElement not found

undetected Selenium Over a year ago

@YoussefZahran Can you delete the ~\.m2 folder manually and do a fresh maven compile and let me know the status?

Youssef Zahran Over a year ago

I deleted it and then tried again and I am getting this:

[INFO] BUILD FAILURE  [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project taf: Compilation failure [ERROR] /C:/Users/youss/eclipse-workspace/taf/src/main/java/pages/CheckOutPage.java:[56,20] cannot access org.openqa.selenium.WrapsElement [ERROR]   class file for org.openqa.selenium.WrapsElement not found

@Youssef Zahran Was this issue solved or were you able to find the solution?
