Question

我正在使用gatling-maven-plugin来运行一些性能测试。我只是按照官方文档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>

这是抱怨，因为

        ... 54 more

如果我在配置中添加此行

<disableCompiler>true</disableCompiler>

这是抱怨，因为找不到我的simulationClass

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

知道我做错了吗？

Answer 1

在禁用gatling-maven-plugin后，不确定是否添加了Scala Maven Plugin，但这可能会解释第二个错误，如here所述。您应该通过Gatling插件或Scala插件以某种方式编译Simulation类。

至于第一个错误，它看起来像一个依赖项不匹配问题。确保您使用的是二进制兼容版本的Gatling依赖项以及Scala依赖项。

我希望这有用。

Answer 2

我通过将scala库版本从2.11.6更新到2.11.8

来解决

    <dependency>
        <groupId>org.scala-lang</groupId>
        <artifactId>scala-library</artifactId>
        <version>2.11.8</version>
    </dependency>

Gatling maven插件出错
