我有一个测试，初始化嵌入式Cassandra为

EmbeddedCassandraServerHelper.startEmbeddedCassandra(EmbeddedCassandraServerHelper.CASSANDRA_RNDPORT_YML_FILE, <timeout>)

初始化时在gradle中抛出以下堆栈跟踪

上面清楚地告诉我们，它之所以发生是因为它无法在它正在寻找的地方找到它正在寻找的资源。但我尝试在这里实现其他解决方案，比如将资源复制到 ${buildDir}/classes 或者设置源代码集等。这个问题仅限于gradle构建，在使用maven测试运行时不是问题。
自 target/embeddedCassandra/hints 是从embeddedcassandraserverhelper代码中获取的，我无法将其更改为在类加载器的上下文中使用 getClassLoader() 将资源复制到 build/classes 文件夹本来就没用。
非常感谢您的建议。
