我一直在开发一个 Web 应用程序，它可以生成测试，给定上传的 Java 文件，并针对所述生成的测试测试上传的代码。我一直在使用 Evosuite 毫无问题地生成测试。但是，我刚刚更新到最新版本（1.0.3），现在运行生成的测试时出现以下错误：
initializationError(PackOfCrisps_ESTest)
java.lang.ClassNotFoundException: Class 'PackOfCrisps_ESTest.class' should be in target project, but could not be found!

为了运行测试，我正在创建一个新的类加载器，其中包含指向要测试的文件以及从 Evosuite 生成的测试所在目录的 URL。
在我更新 Evosuite 之前，我的应用程序已经成功运行，但我想继续使用这个新版本，因为附加功能对我的项目很有用。可能有一个我不知道的微妙变化，所以非常感谢任何帮助。
