使用maven-surefire-plugin并行执行正在抛出PluginResolutionException。

Question

我试图通过TestRunner.java文件(在pom.xml中提到它们)并行地执行我的特性文件，使用maven-surefire-plugin，为此我为其设置了下面的pom.xml，但当我将pom.xml作为maven测试运行时，当版本为3.0.0-M3时，它抛出PluginResolutionException，当我将版本更新为2.19.1时，maven测试没有运行我的特性文件，但是构建显示为成功的。

• 我试过不同的版本，但没有起作用。
• 此外，我还尝试用以下更改替换配置部分

仍然没有执行我的功能文件，但是构建是成功的。

<configuration>
<forkCount>3</forkCount>
<reuseForks>true</reuseForks>
<!-- 
<parallel>classes</parallel>
<forkMode>perthread</forkMode>
<threadCount>3</threadCount>
-->
<argLine>-Xmx1024m -XX:MaxPermSize=256m</argLine>
<includes>
<include>**/*TestRunner.java</include>
</includes>
</configuration>

PS:在阅读了下面的文章parallel之后

我了解到在我的项目中使用的Junit版本和surefireflugin之间有联系，有一点是肯定的，Junit和maven-surefire插件的正确组合是非常必要的，我已经尝试了下面的组合

JUnit 4.7
plugin 3.0.0-M3

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>3.0.0-M3</version>
<dependencies>
<dependency>
<groupId>org.apache.maven.surefire</groupId>
<artifactId>surefire-junit47</artifactId>
<version>3.0.0-M3</version>
</dependency>
</dependencies>
</plugin> 

JUnit 4.12
plugin 2.20

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.20</version>
<configuration>
<parallel>classes</parallel>
<threadCount>3</threadCount>
<argLine>-Xmx1024m -XX:MaxPermSize=256m</argLine>
<includes>
<include>**/*TestRunner.java</include>
</includes>
</configuration>
</plugin>

但是这没有帮助，我想我在选择这个版本和适当参数的插件配置时做错了，请帮助我。

预期:我的功能文件应该并行运行:我的特性文件没有执行。

​

​

在按照sureshmani的建议更改依赖项和插件之后，它是这样的。

​

Answer 1

最后，我能够解决这个问题，对我最初的pom，已经开始做下面的修改。它并行运行我的功能文件。

更改1:我碰巧添加了黄瓜-jvm并行插件的依赖项以及插件，所以我删除了插件。

改变2:我已经意识到当我放置src/main/java时，黄瓜-jvm并行插件无法识别这些特性文件，一些帖子说我必须将所有的特性文件移到src/main/resources/feature，其中的特性是包的。

更改3:我已经意识到黄瓜-jvm并行插件无法识别像步骤def和驱动程序等资源，所以我使用了plugin，其中我声明了下面的资源

<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<version>1.7</version>
<executions>
<execution>
<id>add-source</id>
<phase>generate-sources</phase>
<goals>
<goal>add-source</goal>
</goals>
<configuration>
<sources>
<source>src/main/java/</source>
<source>src/main/resources/</source>
<source>features</source>
</sources>
</configuration>
</execution>
</executions>
</plugin>

更改4:我的IDE中maven生命周期中的黄瓜-jvm-并行插件，因为出于某种原因，maven无法在它执行Eclipse -> Windoes > Preferences ->Maven-> life >复制粘贴下面的代码中考虑这个插件

<pluginExecution>
<pluginExecutionFilter>
<groupId>com.github.temyers</groupId>
<artifactId>cucumber-jvm-parallel-plugin</artifactId>
<goals>
<goal>generateRunners</goal>
</goals>
<versionRange>[4.2.0,)</versionRange>
</pluginExecutionFilter>
<action>
<ignore/>
</action>
</pluginExecution>
Then , click on "Reload workspace lifecycle mapping metadata" button in Preference 
Maven modal

My final pom looks like this

Even after these changes, an error started showing at <execution> in pom, it says 
Plugin execution not covered by lifecycle configuration: com.github.temyers:cucumber- 
jvm-parallel-plugin:4.2.0:generateRunners (execution: generateRunners, phase:

But, its fine, i am able to run the feature files in parallel even with this above 
error
