java - 如何修复 : java. lang.ClassNotFoundException : BasicSimulation for gradle gatlingRun task?

Question

我正在尝试通过 gradle 运行 gatling 任务。我专门设置了我的 scala 源代码集，在运行 gatlingRun 之前运行 compileScala，但我不断收到错误消息: java.lang.ClassNotFoundException: BasicSimulation

如何正确设置任务？ build.gradle:

plugins {
    id "com.github.lkishalmi.gatling" version "3.0.2"
}
repositories {
    mavenCentral()
}
apply plugin: 'java'
apply plugin: 'scala'

sourceSets {
    main {
        scala {
            srcDirs = ['src/gatling/simulations/']
        }
    }
}



dependencies {
    compile "io.gatling:gatling-core:3.0.2"
    compile "io.gatling:gatling-http:3.0.2"
    compile 'io.gatling.highcharts:gatling-charts-highcharts:3.0.2'
    compile 'org.scala-lang:scala-library:2.11.8'
}

gatling {
    simulations = {
        include "*.scala"
    }
}

渐变语法: gradlew compileScala gatlingRun -Dorg.gradle.java.home=C:\Users\saber.alex\Documents\jre1.8.0_91

错误:

gatling 中存在与更改源目录相关的错误。 https://github.com/gatling/gatling/issues/3301

尝试使用默认目录进行模拟。它在 SBT 项目中对我有帮助。
