我正在编写一个sbt插件（sbt 0.13.5），它提供与Cassandra交互的任务（使用数据交换驱动程序）。当调用插件的任务时，sbt控制台打印由第三方类（数据存储驱动程序）创建的日志输出，该输出不应显示给用户（以[pool-445-thread-1]开头的行）：
[sbt-pillar-plugin-play-sample] $ createKeyspace

使用slf4j的FrameCompressor日志，我为测试sbt插件而创建的示例项目正在使用play 2.3.0。
我已经尝试在logback.xml sbt插件中放置一个src/main/resources但没有成功 - 日志消息仍然显示。
如何将FrameCompressor的日志级别设置为ERROR？
