我正在尝试将 Spring 的自定义 Tomcat 类加载器放入我用于 Gradle 项目集成测试的嵌入式 Tomcat 实例中，因为我计划使用加载时间织入。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工作正常，但是我如何访问嵌入式 Tomcat 实例的文件夹并放置jar 在 boostrap 类加载器找到它之前就在那里？
https://github.com/bmuschko/gradle-tomcat-plugin/
在进行建议的更改之前，我遇到了这个错误
java.lang.ClassNotFoundException: org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader
在进行了建议的更改后，我收到了一个新错误。这是我的 build.gradle，其中包含构建脚本中的更改

最佳答案
添加到你的build.gradle
buildscript {
dependencies {
classpath files('/tmp/spring-instrument-tomcat-3.2.5.RELEASE.jar')
}
}
或者
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath group: 'org.springframework', name: 'spring-instrument-tomcat', version: '3.2.5.RELEASE'
}
}
