执行 JaCoCo 时出现“由于缺少执行数据文件而跳过 JaCoCo 执行”

2023-11-27

我正在使用 Maven 3.0.3、JUnit 4.8.1 和 Jacoco 0.6.3.201306030806，并且我正在尝试创建测试覆盖率报告。

我有一个仅包含单元测试的项目，但无法运行报告，我反复收到错误：Skipping JaCoCo execution due to missing execution data file当我跑步时：

mvn clean install -P test-coverage

这是我的 pom 的配置方式：

<plugin>

            </goals>
          </execution>
          <!-- prepare agent for measuring integration tests -->
          <execution>
            <id>prepare-integration-tests</id>
            <goals>

            </goals>

            <configuration>
              <propertyName>itCoverageAgent</propertyName>
            </configuration>
          </execution>
          <execution>
            <id>jacoco-site</id>

          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
</profile>

我的所有测试都成功运行。以下是 Maven 的一些输出：

有什么想法我缺少什么配置吗？

jacoco-maven-插件：0.7.10-SNAPSHOT

From jacoco:准备代理说的是：

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：
<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-surefire-plugin</artifactId>
  <configuration>
    <argLine>@{argLine} -your -extra -arguments</argLine>
  </configuration>
</plugin>

请注意@{argLine}添加到-your -extra -arguments.

Thanks 斯拉瓦·塞姆申注意到变化并在评论中举报.

jacoco-maven-插件：0.7.2-SNAPSHOT

下列的jacoco:准备代理说的是：

[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，该代理可以作为 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：

tycho.testArgLine 用于打包类型 eclipse-test-plugin 和

argLine 否则。

请注意，这些属性不得被覆盖测试配置，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：
<argLine>${argLine} -your -extra -arguments</argLine>
结果覆盖率信息是在执行期间默认收集的当进程终止时写入文件。

你应该改变以下行maven-surefire-plugin插件配置来自（注意${argLine} inside <argLine>):

<argLine>-Xmx2048m</argLine>

<argLine>${argLine} -Xmx2048m</argLine>

对其他插件也进行必要的更改maven-failsafe-plugin并替换以下内容（再次注意${argLine}):

<argLine>-Xmx4096m -XX:MaxPermSize=512M ${itCoverageAgent}</argLine>

<argLine>${argLine} -Xmx4096m -XX:MaxPermSize=512M ${itCoverageAgent}</argLine>
