获取“由于缺少执行数据文件而跳过 JaCoCo 执行"；在执行 JaCoCo 时 [英] Getting "Skipping JaCoCo execution due to missing execution data file" upon executing JaCoCo
问题描述
我正在使用 Maven 3.0.3、JUnit 4.8.1 和 Jacoco 0.6.3.201306030806，我正在尝试创建测试覆盖率报告.
I'm using Maven 3.0.3, JUnit 4.8.1, and Jacoco 0.6.3.201306030806, and I am trying to create test coverage reports.
我有一个只有单元测试的项目，但我无法运行报告，我反复收到错误:Skipping JaCoCo execution due to missing execution data file 当我运行时:
I have a project with unit tests only, but I can't get reports to run, I'm repeatedly getting the error: Skipping JaCoCo execution due to missing execution data file when I run:
mvn clean install -P test-coverage
这是我的 pom 的配置方式:
Here is how my pom is configured:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.14.1</version>

我所有的测试都成功运行.以下是 Maven 的一些输出:
All my tests run successfully. Here is some of the output from Maven:

知道我缺少什么配置吗?
Any ideas what configuration I'm missing?
推荐答案
jacoco-maven-plugin:0.7.10-SNAPSHOT
来自 jacoco:prepare-agent 说:
在 maven-surefire-plugin 的情况下执行此操作的方法之一是使用语法进行后期属性评估:
One of the ways to do this in case of maven-surefire-plugin - is to use syntax for late property evaluation:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<argLine>@{argLine} -your -extra -arguments</argLine>
</configuration>
</plugin>
注意添加到 -your -extra -arguments 中的 @{argLine}.
Note the @{argLine} that's added to -your -extra -arguments.
感谢 Slava Semushin 注意到变化和 在评论中报告.
Thanks Slava Semushin for noticing the change and reporting in the comment.
按照 jacoco:prepare-agent 说:
[org.jacoco:jacoco-maven-plugin:0.7.2-SNAPSHOT:prepare-agent] 准备一个指向 JaCoCo 运行时代理的属性，它可以被作为 VM 参数传递给被测应用程序.根据项目打包类型默认具有以下属性名称已设置:
[org.jacoco:jacoco-maven-plugin:0.7.2-SNAPSHOT:prepare-agent] Prepares a property pointing to the JaCoCo runtime agent that can be passed as a VM argument to the application under test. Depending on the project packaging type by default a property with the following name is set:
- tycho.testArgLine 用于打包类型 eclipse-test-plugin 和
- argLine 否则.
注意这些属性不能被覆盖测试配置，否则无法附加JaCoCo代理.如果您需要自定义参数，请附加它们.例如:
Note that these properties must not be overwritten by the test configuration, otherwise the JaCoCo agent cannot be attached. If you need custom parameters please append them. For example:
<argLine>${argLine} -your -extra -arguments</argLine>
结果覆盖信息是在执行期间收集的，默认情况下进程终止时写入文件.
Resulting coverage information is collected during execution and by default written to a file when the process terminates.
您应该在 maven-surefire-plugin 插件配置中更改以下行(注意 ${argLine}>):
you should change the following line in maven-surefire-plugin plugin configuration from (note the ${argLine} inside <argLine>):
<argLine>-Xmx2048m</argLine>
到
<argLine>${argLine} -Xmx2048m</argLine>
也对其他插件maven-failsafe-plugin 进行必要的更改并替换以下内容(再次注意${argLine}):
Make also the necessary changes to the other plugin maven-failsafe-plugin and replace the following (again, notice the ${argLine}):
<argLine>-Xmx4096m -XX:MaxPermSize=512M ${itCoverageAgent}</argLine>
到
<argLine>${argLine} -Xmx4096m -XX:MaxPermSize=512M ${itCoverageAgent}</argLine>
