scala - Gatling maven插件错误

Question

我正在使用 gatling-maven-plugin 来运行一些性能测试。我就按照官方文档http://gatling.io/docs/2.2/extensions/maven_plugin/

我有这个配置

<!--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>

它提示是因为

        ... 54 more

如果我在配置中添加这一行

<disableCompiler>true</disableCompiler>

提示是因为找不到我的模拟类

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

知道我做错了什么吗？

Answer 1

不确定您是否添加了 Scala Maven Plugin或者在禁用 gatling-maven-plugin 之后没有，但这可能解释了第二个错误，如 here 所述.您应该通过 Gatling 插件或 Scala 插件以某种方式编译您的 Simulation 类。

至于第一个错误，它看起来像是一个依赖不匹配的问题。确保您使用的是 Gatling 依赖项以及 Scala 依赖项的二进制兼容版本。

希望对您有所帮助。
