我的 Jacoco 报告目标不绑定到测试阶段答案

【问题标题】：My Jacoco report goal is not binding to the test phase我的 Jacoco 报告目标不绑定到测试阶段
【发布时间】：2016-07-16 13:54:46
【问题描述】：

在 target/coverage-reports/jacoco-ut.exec 中创建了 jacoco-ut.exec 文件，但看不到 site/ 目录。

这里是 Jacoco 配置：

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.19.1</version>
    <configuration>

      </excludes>
    </configuration>
  </plugin>

        <configuration>
          <destFile>${project.build.directory}/coverage-reports/jacoco-ut.exec</destFile>
          <propertyName>surefireArgLine</propertyName>
        </configuration>
      </execution>
      <execution>

        <phase>test</phase>
        <goals>
          <goal>report</goal>
        </goals>
        <configuration>
          <dataFile>${project.build.directory}/coverage-reports/jacoco-ut.exec</dataFile>
          <outputDirectory>${project.reporting.outputDirectory}/jacoco-ut</outputDirectory>
        </configuration>
      </execution>
    </executions>
  </plugin>

这是控制台输出：

仅此而已。

更新：我运行了以下命令：mvn jacoco:report -X 它说了一些有趣的事情：

[DEBUG]   (f) dataFile = /home/stephane/dev/java/projects/x/x/x/target/jacoco.exec
[DEBUG]   (f) outputDirectory = /home/stephane/dev/java/projects/x/x/x/target/site/jacoco

[DEBUG] -- end configuration --
[INFO] Skipping JaCoCo execution due to missing execution data file:/home/stephane/dev/java/projects/x/x/x/target/jacoco.exec

当我让它创建一个 jacoco-ut.exec 文件时，它正在查找一个 jacoco.exec 文件。

自从文件创建以来，这有点令人惊讶：

$ ll target/coverage-reports/jacoco-ut.exec 
-rw-rw-r-- 1 stephane 2.9M Mar 29 09:47 target/coverage-reports/jacoco-ut.exec

我想我需要在报告配置中的某处指定该文件名。

更新：在 Jacoco 配置中移动上面的 destFile 和 dataFile 配置后，问题得到解决，并且在 site/ 目录中生成报告。

完整的插件现在看起来像：

  <plugin>
    <groupId>org.jacoco</groupId>
    <artifactId>jacoco-maven-plugin</artifactId>
    <version>0.7.6.201602180812</version>

      <destFile>${project.build.directory}/coverage-reports/jacoco-ut.exec</destFile>
      <dataFile>${project.build.directory}/coverage-reports/jacoco-ut.exec</dataFile>
      <skip>${skipTests}</skip>
      <output>file</output>
      <append>true</append>
    </configuration>
    <executions>
      <execution>
        <id>pre-unit-test</id>

        </goals>
        <configuration>
          <propertyName>surefireArgLine</propertyName>
        </configuration>
      </execution>
      <execution>
        <id>post-unit-test</id>
        <phase>test</phase>
        <goals>
          <goal>report</goal>
        </goals>
        <configuration>
          <outputDirectory>${project.reporting.outputDirectory}/jacoco-ut</outputDirectory>
        </configuration>
      </execution>
    </executions>
  </plugin>

虽然插件是在 plugins 元素中定义的，而不是在 pluginManagement 元素中定义的，但要获取报告我仍然需要执行命令：

mvn jacoco:report

我希望在运行命令时生成报告：

mvn clean install

【问题讨论】：

标签： maven jacoco

【解决方案1】：

使用此配置，生成带有mvn clean install 的站点应该不会有任何问题。

在站点文件夹中会有两个不同的文件夹：jacoco 包含单元测试报告和 jacoco-it 包含集成测试报告。

JaCoco 配置

配置 Jacoco 以公开配置变量以集成单元测试 (jacoco.argLine) 和集成测试 (jacoco.it.argLine) 并生成包含集成测试报告的文件夹 (jacoco-it)：

故障安全配置

        <plugin>
            <artifactId>maven-failsafe-plugin</artifactId>
            <executions>
                <execution>

                    </goals>
                    <configuration>

                        <includes>
                            <include>**/*IT.java</include>
                        </includes>
                        <excludes>
                            <exclude>**/Application.java</exclude>
                        </excludes>
                        <argLine>${jacoco.it.argLine}</argLine>
                        <encoding>UTF-8</encoding>
                        <runOrder>alphabetical</runOrder>
                    </configuration>
                </execution>
            </executions>
        </plugin>

看看<argLine>${jacoco.it.argLine}</argLine>。这个占位符将被 JaCoco 插件指定的所有参数替换。它将包含将 JaCoco 与集成测试集成所需的配置变量。

Surefire 配置

        <plugin>
            <artifactId>maven-surefire-plugin</artifactId>
            <configuration>
                <redirectTestOutputToFile>true</redirectTestOutputToFile>
                <includes>
                    <include>**/*Test.java</include>
                </includes>
                <excludes>
                    <exclude>**/*IT.java</exclude>
                    <exclude>**/Application.java</exclude>
                </excludes>
                <argLine>
                    ${jacoco.argLine}
                </argLine>
                <!-- Force alphabetical order to have a reproducible build -->
                <runOrder>alphabetical</runOrder>
            </configuration>
            <dependencies>
                <dependency>
                    <groupId>org.apache.maven.surefire</groupId>
                    <artifactId>surefire-junit47</artifactId>
                    <version>2.15</version>
                </dependency>
            </dependencies>
        </plugin>

再次查看<argLine>${jacoco.argLine}</argLine>。它将包含将 JaCoco 与单元测试集成所需的配置变量。

【讨论】：

感谢您分享您的配置。但我的问题不是我无法运行 Jacoco 插件，而是我无法在安装阶段运行它。我们的配置之间唯一不同的是您使用准备包阶段来实现报告目标。所以我尝试了它并用准备包阶段替换了我的测试阶段。但它并没有改变任何东西，问题仍然存在。
尝试使用mvn verify触发jacoco执行
调用验证阶段没有区别。如问题所述，我已经在运行安装阶段，该阶段在验证阶段之后。如果需要，请参阅maven.apache.org/guides/introduction/… 的阶段。
是的，你是对的。使用 mvn install 就足够了。有点奇怪，正确配置了 jacoco，您应该会看到所有报告。使用我共享的配置，我没有任何问题。每次执行 mvn clean install 时，我都可以看到 jacoco 报告。我也试过你的 Jacoco 版本，它在我的项目中运行良好。您能否检查一下在 mvn 执行期间是否可以看到此跟踪：[INFO] --- jacoco-maven-plugin:0.7.6.201602180812:report (report-it) @ yourproject ---？
嗨，很抱歉回来晚了。我终于注意到了一件事。使用 -DskipTests=false 选项运行命令时，我看不到您上面的 INFO 级别输出。但是，如果我不使用该选项并且跳过了测试，那么我会看到：`[INFO] 跳过了测试。 [INFO] [INFO] --- jacoco-maven-plugin:0.7.6.201602180812:report (jacoco-unit-test-report) @MyApp ---
