我的最终目标是运行netflix karyon示例https://medium.com/@sarinduudagepala/introduction-收件人：netflix-karyon-266f9ae032fb
我对grad尔和卡里恩还不熟悉。所以，在开始讨论太多未知的问题之前，我用gradle做了一个例子，它使用了jackson依赖关系并将json对象封送到文件。它还使用自定义gradle任务来执行应用程序。效果很好。
任务
ext {
javaMainClass = "TestGradle.Library"
}
task runWithJavaExec(type: JavaExec) {
group = "Execution"
description = "Run the main class with JavaExecTask"
classpath = sourceSets.main.runtimeClasspath
main = javaMainClass
}在本例中，很明显gradle自定义任务正在处理外部依赖项。
现在，当我在链接中尝试这个例子时，我得到了如下错误
