我正试图将Spring的自定义Tomcat类加载器放入我的嵌入式Tomcat实例中，我在Gradle项目中使用该实例进行集成测试，因为我计划使用加载时编织。当我将spring-instrument-tomcat-3.2.5.RELEASE.jar放入apache-tomcat-7.0.40/lib文件夹时，它在我的正常安装中运行良好，但我如何访问嵌入式tomcat实例的文件夹，并在boostrap类加载器找到它之前将jar放在那里？
https://github.com/bmuschko/gradle-tomcat-plugin/
在做出建议的更改之前，我得到了这个错误
java.lang.ClassNotFoundException: org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader
在做出建议的更改后，我得到了一个新的错误。这是我的build.gradle，其中包含构建脚本中的更改
