Question

我在Scala项目中使用Slick 3.1.1。我的build.sbt libraryDependencies包含以下内容：

"com.typesafe.slick"  %% "slick"           % "3.1.1",
"com.typesafe.slick"  %% "slick-hikaricp"  % "3.1.1",    
"com.zaxxer"          % "HikariCP"         % "2.4.3",
"mysql"               % "mysql-connector-java" % "5.1.38",

一切正常。但是，当我尝试使用sbt-assembly部署时，我会收到如下错误：

[error] deduplicate: different file contents found in the following:
[error] /home/thunderkid/.ivy2/cache/com.zaxxer/HikariCP-java6/bundles/HikariCP-java6-2.3.7.jar:com/zaxxer/hikari/pool/HikariPool.class
[error] /home/thunderkid/.ivy2/cache/com.zaxxer/HikariCP/bundles/HikariCP-2.4.3.jar:com/zaxxer/hikari/pool/HikariPool.class

我该如何解决这些问题？

以前我使用的是Slick 3.0，它不需要slick-hikaricp，而且运行正常。我尝试删除.ivy2/cache/com.zaxxer/HikariCP-java6，但这不起作用 - 它只是重新创建。我的mergeStrategy是

mergeStrategy in assembly <<= (mergeStrategy in assembly) { (old) =>
    {
        case PathList(ps @ _*) if ps.last endsWith "ArgumentsProcessor.class" => MergeStrategy.first
        case PathList(ps @ _*) if ps.last endsWith "MatchersBinder.class" => MergeStrategy.first
        case "application.conf" => MergeStrategy.concat
        case "unwanted.txt"     => MergeStrategy.discard
        case x => old(x)
    }
}

在上面的评论中关注@ brettw的建议，我通过在exclude中添加build.sbt命令来实现它，如下所示：

"com.typesafe.slick"  %% "slick-hikaricp"  % "3.1.1"   exclude("com.zaxxer", "HikariCP-java6"),

使用sbt-assembly
