Maven won't compile Selenium dependencies

Question

I built a project in IntelliJ using the JavaFX and Selenium libraries. When ran inside the IDE, the project functions as intended. When compiled with mvn clean;mvn compile, and than executed via it's newly created .jar file, the JavaFX part of the program works, but the Selenium libraries can not be found. This is my pom.xml file:

<?xml version="1.0" encoding="UTF-8"?>

How do I successfully build this project so the Selenium dependencies defined in the pom work outside of the IDE?

Answer 1

The problem is that your jar's classpath points to the relative directory lib/ while your dependencies are being copied to ${com.toasttab.Epsonaut}/lib.

Just make sure<outputDirectory> have the same value as <classpathPrefix>.

If you want to be able to execute the jar from any path, I would suggest to use maven-assembly-plugin with the single goal.

<build>
  <plugins>
    <plugin>
      <artifactId>maven-assembly-plugin</artifactId>
      <configuration>
        <archive>
          <manifest>
            <mainClass>your.package.MainClass</mainClass>
          </manifest>
        </archive>
        <descriptorRefs>
          <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
      </configuration>
    </plugin>
  </plugins>
</build>

and run it with mvn clean compile assembly:single.

Answer 2

Open final jar file through ZIP, check MANIFEST.MF file Class-Path: values.
All paths there must be accessible from current directory.
Current means from where you call java to execute that jar file.
