我正在尝试在小型 vanilla ubuntu 12 机器上运行 cassandra 单元测试，但测试或 repl 立即崩溃而没有给我任何信息。当我在 repl 中尝试它时，我得到以下信息：

原来我需要> 4GB的内存来进行单元测试。从env JAVA_OPTS="-Xmx5G" sbt test解决它开始。

乍一看，问题似乎是多个 SLF4J 绑定。您有多个带有 slf4j 记录器的罐子。

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/root/.ivy2/cache/ch.qos.logback/logback-classic/jars/logback-classic-1.1.2.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/root/.ivy2/cache/org.slf4j/slf4j-log4j12/jars/slf4j-log4j12-    1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class]

删除其中任何一个，然后重试。

您可以参考：http ://www.slf4j.org/codes.html#multiple_bindings以获得解释
