加特林sbt組裝jar文件不能創建？

我正在使用gatling工具進行性能測試。我的gatling代碼運行完美。我正在爲我的項目使用intellij IDEA。我正在嘗試創建一個jar文件。它不能創建。我認爲這是SBT problem.please有人糾正我的SB我build.sbt文件是在這裏：加特林sbt組裝jar文件不能創建？

import io.gatling.sbt.GatlingPlugin 
import sbtassembly.MergeStrategy 

parallelExecution in Test := false 
enablePlugins(GatlingPlugin, AssemblyPlugin) 
lazy val root = (project in file(".")) 
.configs(IntegrationTest) 
.settings(Defaults.itSettings: _*) 

Project.inConfig(IntegrationTest)(baseAssemblySettings) 
mainClass in assembly := Some("gatling.GatlingMain") 
assemblyMergeStrategy in assembly := { 
case x => 
val oldStrategy = (assemblyMergeStrategy in assembly).value 
oldStrategy(x) 
} 
libraryDependencies ++= Seq(
"com.typesafe.play" % "play-json_2.11" % "2.6.2" % IntegrationTest, 
"org.scalacheck" % "scalacheck_2.11" % "1.13.5" % IntegrationTest, 
"com.typesafe" % "config" % "1.3.1" % IntegrationTest, 
"io.gatling.highcharts" % "gatling-charts-highcharts" % "2.2.5" % 
IntegrationTest, 
"io.gatling" % "gatling-test-framework" % "2.2.5" % IntegrationTest, 
"com.google.code.gson" % "gson" % "2.8.0" % IntegrationTest 
) 
resourceDirectory in Compile := baseDirectory.value /"resources" 
assemblyJarName in (IntegrationTest, assembly):=s"${name.value}-${version.value}.jar"

當我嘗試使用創建一個jar文件SBT命令SBT「吧：集結號」它顯示了以下錯誤

我的sbt版本是0.13.16，我的scala版本是2.11.8。請有人幫我解決這個錯誤。在此先感謝

很可能你不需要所有io.netty庫中的io.netty.versions.properties，可能就足夠了。我認爲這樣的事情應該可以工作：

assemblyMergeStrategy in assembly := { 
case p if p.endsWith("io.netty.versions.properties") => 
    MergeStrategy.first 
case x => 
    val oldStrategy = (assemblyMergeStrategy in assembly).value 
    oldStrategy(x) 
}
