Question

我使用JavaFX和Selenium库在IntelliJ中构建了一个项目。在IDE内部运行时，项目按预期运行。当使用mvn clean;mvn compile编译，而不是通过它新创建的.jar文件执行时，程序的JavaFX部分可以工作，但找不到Selenium库。这是我的pom.xml文件：

如何成功构建此项目，以便在pom中定义的Selenium依赖项在IDE之外工作？

编辑：我的MANIFEST.MF文件位于下方。

Answer 1

问题是，当您的依赖项被复制到lib/时，您的jar的类路径指向相对目录${com.toasttab.Epsonaut}/lib。

确保<outputDirectory>与<classpathPrefix>具有相同的价值。

如果您希望能够从任何路径执行jar，我建议将maven-assembly-plugin与single目标一起使用。

<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>

并使用mvn clean compile assembly:single运行它。

Answer 2

通过ZIP打开最终jar文件，检查MANIFEST.MF文件Class-Path：值。
必须可从当前目录访问其中的所有路径。
当前意味着您调用java来执行该jar文件。

Maven不会编译Selenium依赖项
