我正在处理一个桌面项目，在这个项目中，我动态地向打包的jar中添加一个java类，并在编译后执行相同的java类。我的java类有一些selenium导入，我在项目中添加了selenium作为maven依赖项，但是在运行时编译java文件时，无法识别导入。请帮助我怎样才能使它工作。
以下是用户生成的java类的内容：

import java.util.*;
import java.io.*;
import java.math.*;
import java.lang.*;
import org.openqa.selenium.*;
public class CustomClass{
public boolean WebElementVisible(WebDriver driver, WebElement zipCode) {
    if (zipCode.isEnabled()) {
      return true;
    }
    return false;
  }
}

这就是我如何将生成的java文件添加并编译到打包jar的类路径中。

DiagnosticCollector<JavaFileObject> diagnostics = new DiagnosticCollector<JavaFileObject>();
    JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();
    StandardJavaFileManager fileManager = compiler.getStandardFileManager(diagnostics, null, null);

    List<String> optionList = new ArrayList<String>();
    optionList.add("-classpath");
    optionList.add(System.getProperty("java.class.path") + File.pathSeparator +);
    Iterable<? extends JavaFileObject> compilationUnit = fileManager
                    .getJavaFileObjectsFromFiles(Arrays.asList(tempCustomFile));
    // file manager in the below is the path of my dynamically added java class
    JavaCompiler.CompilationTask task = compiler.getTask(null, fileManager, diagnostics, optionList, null,
                    compilationUnit);
        if (task.call()) {

                URLClassLoader classLoader = new URLClassLoader(
                        new URL[] { new File(operationalFolderPath).toURI().toURL() });

                        for (Method methodInClass : methods) {

                            }

                        try {

当我通过eclipse运行相同的代码时，它工作得很好，我可以使用selenium，但当我将项目打包为jar时，它就不工作了。表示无法识别包org.openqa.selenium.*；
