【问题描述】：
我想在一个 gatling sbt 项目中使用命令行参数传递加速用户、限制持续时间、保持持续时间等。
例如：
val rampUpUserCount = Integer.parseInt(System.getProperty("rampUpUsers"))
val rampUpDuration = Integer.getInteger(System.getProperty("rampUpDuration"))
在我正在做的测试中
setUp(
test.homePageScenario.inject(
nothingFor(10 seconds),
rampUsers(rampUpUserCount) over (rampUpDurationInMins minutes)
))
当我通过时从命令行
sbt gatling:testOnly simulations.test.gateway -DrampUpUsers=200 -DrampUpDuration=20
我收到NumberFormatException

请问有人可以帮我解决这个问题吗？ 谢谢
