加特林maven插件中的錯誤

Question

我正在使用gatling-maven-plugin運行一些性能測試。 我只是按照官方文檔http://gatling.io/docs/2.2/extensions/maven_plugin/

我有這個配置

<!--PERFORMANCE TEST--> 
     <plugin> 
      <groupId>io.gatling</groupId> 
      <artifactId>gatling-maven-plugin</artifactId> 
      <version>2.2.4</version> 
      <configuration> 
       <!--<disableCompiler>true</disableCompiler>--> 
       <configFolder>${project.basedir}/src/test/resources</configFolder> 
       <dataFolder>${project.basedir}/src/test/resources/data</dataFolder> 
       <resultsFolder>${project.basedir}/target/gatling/results</resultsFolder> 
       <bodiesFolder>${project.basedir}/src/test/resources/bodies</bodiesFolder> 
       <simulationsFolder>${project.basedir}/src/test/scala/performance/</simulationsFolder> 
       <runDescription>This-is-the-run-description</runDescription> 
       <simulationClass>${project.basedir}\src\test\scala\performance\TillScenario</simulationClass> 
      </configuration> 
      <executions> 
       <execution> 
        <goals> 
         <goal>integration-test</goal> 
        </goals> 
       </execution> 
      </executions> 
     </plugin> 
    </plugins> 

it's抱怨，因爲

，如果我在配置上加入這一行

<disableCompiler>true</disableCompiler> 

它的投訴，因爲不能fi nd我的模擬類

Caused by: java.lang.IllegalArgumentException: The requested class 'path\TillScenario' can not be found in the classpath or does not extends Simulation. 

任何想法我做錯了什麼？

不確定是否在禁用gatling-maven-plugin後添加了Scala Maven Plugin，但這可能會解釋第二個錯誤，如here所述。您應該通過Gatling插件或Scala插件以某種方式編譯您的Simulation類。

至於第一個錯誤，它看起來像一個依賴項不匹配問題。確保您使用的是Gatling依賴關係的二進制兼容版本以及Scala版本。

我希望這是有幫助的。
