WebdriverManager throws java.lang.ClassNotFoundException: io.netty.handler.codec.compression.Brotli in Selenium 4.0

When chrome driver initialised, with selenium 4.0 and webdriver manager maven dependency 4.2.0

It throws

java.lang.ClassNotFoundException: io.netty.handler.codec.compression.Brotli

Causing

org.openqa.selenium.SessionNotCreatedException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.

As a result, even though browser window is launched , session is not created.

Solution

  • This is due to MAVEN dependency conflicts to solve this added below dependency and worked successfully.

    <dependency>
    <groupId>io.netty</groupId>
    <artifactId>netty-handler</artifactId>
    <version>4.1.69.Final</version>
</dependency>
