我有一个将嵌入式cassandra初始化为
的测试EmbeddedCassandraServerHelper.startEmbeddedCassandra(EmbeddedCassandraServerHelper.CASSANDRA_RNDPORT_YML_FILE, <timeout>)
初始化时会在Gradle中引发以下堆栈跟踪

上面的内容清楚地表明了这种情况的发生，因为它无法在所需的位置找到所需的资源。但是我试图在这里实现其他解决方案，例如将资源复制到${buildDir}/classes或设置源集等。此问题仅限于gradle构建，而在进行maven测试时不是问题。
由于target/embeddedCassandra/hints是从EmbeddedCassandraServerHelper代码中获取的，所以无法使用getClassLoader()将其更改为在类加载器的上下文中获取，从而将资源复制到build/classes文件夹中本质上是无用的。
建议深表感谢。
