Question

我正在gitlab上的一个项目上，我试图利用maven的gatling插件来运行模拟。

我已经将gatling的依赖项添加到了项目以及相应的插件中，但是我每当运行mvn gatling:test时都会遇到此错误通过gitlab的管道，甚至在项目的本地进行

错误：

[ERROR] Failed to execute goal io.gatling:gatling-maven-plugin:2.2.4:test (default-cli) on project myproject: Gatling failed.: Couldn't locate org.s
cala-lang:scala-library in classpath -> [Help 1]
[ERROR]
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.
[ERROR]
[ERROR] For more information about the errors and possible solutions, please read the following articles:
[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/MojoExecutionException

我对是否满足依赖项有一些疑问，因此我尝试了mvn dependency:get

YAML：

script:
  - echo "Hello World!"
  - uname -a
  - pwd
  #- mvn dependency:get -e -Dartifact=io.gatling:gatling-maven-plugin:2.2.4
  #- mvn dependency:get -e -Dartifact=io.gatling.highcharts:gatling-charts-highcharts:2.2.5
  - mvn -Dmaven.test.skip=true clean install -e
  - mvn gatling:test -e

堆栈跟踪：

Gatling failed.

编辑：我为项目创建了一个额外的模块，并仅向其添加了加特林依赖项。

mvn gatling:test is now working and returns `No Simulations to run`

我还没有在项目中添加模拟。这意味着问题与父pom有关，因为存在许多依赖项以及我什至不认识的其他标签。

如果您在gatlin-charts docs-下检查您正在使用的java.io.IOException: Is a directory at java.base/sun.nio.ch.FileDispatcherImpl.read0(Native Method) at java.base/sun.nio.ch.FileDispatcherImpl.read(FileDispatcherImpl.java:48) at java.base/sun.nio.ch.IOUtil.readIntoNativeBuffer(IOUtil.java:283) at java.base/sun.nio.ch.IOUtil.read(IOUtil.java:250) at java.base/sun.nio.ch.FileChannelImpl.read(FileChannelImpl.java:223) at java.base/sun.nio.ch.ChannelInputStream.read(ChannelInputStream.java:65) at java.base/sun.nio.ch.ChannelInputStream.read(ChannelInputStream.java:109) at java.base/sun.nio.ch.ChannelInputStream.read(ChannelInputStream.java:103) at java.base/java.nio.file.Files.read(Files.java:3163) at java.base/java.nio.file.Files.readAllBytes(Files.java:3216) at hw2.FileUtilities.slurp(FileUtilities.java:46) at hw2.FileUtilities.main(FileUtilities.java:14) -库，请向下滚动，最后一节，然后查看相关性：

如您所见，在日志中，您有一条gatling-plugin消息，内容为：

加特林失败。：无法在以下位置找到org.s cala-lang：scala-library 类路径

因此，您需要将Scala依赖项添加到声明插件的父gatlin-plugin中。

pom.xml

如果单击该页面上的版本号，将转到所需的 <dependency> <groupId>org.scala-lang</groupId> <artifactId>scala-library</artifactId> <version>2.11.8</version> </dependency>版本：

https://mvnrepository.com/artifact/org.scala-lang/scala-library/2.11.8

注意：请记住，您可以add dependencies specifically使用这样的插件：

scala-charts

使用GitLab CI / CD
