PlayFramework多个SLF4J绑定 [英] PlayFramework Multiple SLF4J bindings

问题描述

我正在尝试完成某些模型的一些基本单元测试.但是我收到以下错误.现在看来，我有两个SLF4J绑定.这是因为我使用的Mahout具有SLF4J的一个版本，而Play具有其自己的版本.

I'm trying to complete some basic unit tests of some models. However I'm getting the following error. Now it appears I have two bindings for SLF4J. This is because I am using Mahout which has one version of SLF4J and Play has its own version.

谁能告诉我如何解决这个问题?

Can anyone tell me how I can resolve this problem?

SLF4J:请参见 http://www.slf4j.org/codes.html#multiple_bindings进行解释. SLF4J:在类路径上检测到jcl-over-slf4j.jar和slf4j-jcl.jar，从而抢占了StackOverflowError. SLF4J:另请参见 http://www.slf4j.org/codes.html#jclDelegationLoop 有关更多详细信息.

SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation. SLF4J: Detected both jcl-over-slf4j.jar AND slf4j-jcl.jar on the class path, preempting StackOverflowError. SLF4J: See also http://www.slf4j.org/codes.html#jclDelegationLoop for more details.

推荐答案

尝试

"org.apache.mahout" % "mahout-core" % "0.7" excludeAll(ExclusionRule(organization = "org.slf4j"))

获取您的mahout依赖项.

to get your mahout dependency.
