Java Question

Maven won't compile Selenium dependencies

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"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

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

Answer

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.
