java.lang.NoClassDefFoundError while using FirefoxDriver(Selenium) in docker with alpine image-CodePudding

Trying to use FireFox driver for doing some manipulations with webbrowser, but when i dockered my app i faced with error that i posted down.

Using Selenium, Firefox-driver and maven:3.6.1-jdk-8-alpine image with fierfox-esr and xvfb on it

Some piece of program:

@Scheduled(fixedRate = 20000)
    public void main() throws InterruptedException, IOException {
        System.setProperty("webdriver.gecko.driver", "Gecko/geckodriver");

        QueueEntity queue = QueueDAO.next();
        if (queue != null) {
            WebDriver driver = new FirefoxDriver();

Last line causes an error:

All that is running in docker (alpine)

DockerFile:

FROM maven:3.6.1-jdk-8-alpine
COPY ./src /app/src
COPY ./Gecko /app/Gecko
COPY pom.xml /app
WORKDIR /app
EXPOSE 3000
RUN mvn package
Run apk update
Run apk add xvfb
Run apk add firefox-esr
Run Xvfb :9 &
CMD ["mvn", "spring-boot:run"]

Also specifying Display=:9 as an environment variable

Will be glad for any help^_^

CodePudding user response：

Though you mentioned about adding the following dependencies:

<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-java</artifactId>
    <version>4.0.0</version>
</dependency>
<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-api</artifactId>
    <version>4.0.0</version>
</dependency>

But as per the error stack trace your program is looking for:

selenium-remote-driver-3.141.59.jar:na
selenium-remote-driver-3.141.59.jar:na
selenium-firefox-driver-3.141.59.jar:na

Hence, the class definations aren't found and you see the error java.lang.NoClassDefFoundError

Checkout your dockered app configuration to resolve the conflict between Selenium v3.141.59 and v4.0.0
