在 gatling 中，出现“线程“主”java.lang.ExceptionInInitializerError 中的异常”错误

Question

在scala目录下运行Engine.scala，报错：

 Exception in thread "main" java.lang.ExceptionInInitializerError
    at Engine$.delayedEndpoint$Engine$1(Engine.scala:7)
    at Engine$delayedInit$body.apply(Engine.scala:4)

而BaiduHomePageSimulation.scala是：

package test.scala

import io.gatling.core.Predef._
import io.gatling.http.Predef._

class BaiduSimulation extends Simulation {
    // Set the root path of the request
    val httpConf = http.baseUrl("https://www.baidu.com")
    /*
    run 10 seconds, during：the default unit is seconds, if you want to use microseconds eg. during(100 millisecond)
    */
    val scn = scenario("BaiduSimulation").during(10){
        exec(http("baidu_home").get("/"))
    }
    // set the thread count
    setUp(scn.inject(atOnceUsers(10)).protocols(httpConf))
}

不知道怎么解决？有没有人遇到过类似的问题？

我遇到了这个错误，并且能够通过将 scala 目录标记为测试源根目录来解决它
