我们正在为我们的项目使用以下依赖项。
val cassandraConnector = "com.datastax.spark" %% "spark-cassandra-connector" % "2.0.0"
val sparkSql = "org.apache.spark" % "spark-sql_2.11" % "2.2.0"
val phantomDsl = "com.outworkers" % "phantom-dsl_2.11" % "2.15.5"
val cassandraUnit = "org.cassandraunit" % "cassandra-unit" % "3.3.0.2" % "test"
使用命令 sbt 编译测试运行测试用例时。我们收到以下错误：-

依赖性有问题吗？
我们如何摆脱这个错误？
谢谢
这真的很有趣，但是它与幻影无关，而是与番石榴库依赖项有关，该依赖项最终以某种方式与类路径上的内容发生冲突。
简而言之，基本上问题来自二进制不兼容/排除，因此 Spark 或类路径中的其他内容会覆盖 phantom 中的 Guava 版本。
如果您打印出驱逐，我可以进一步帮助您。
我们还提供phantom-sbt作为Cassandra的集成SBT插件，我怀疑这是这里的根本原因，以及通过SBT(仅限专业功能(的Docker集成。也许为 phantom 提交一个 GitHub 问题，一旦我们知道哪些版本冲突，我们就可以更轻松地跟进。
