Головная цель отчета Jacoco не является обязательной для этапа тестирования

Question

Файл jacoco-ut.exec создается в отчетах target/coverage-reports/jacoco-ut.exec, но нет видимого сайта/каталога.

Вот конфигурация Jacoco:

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-surefire-plugin</artifactId> 
    <version>2.19.1</version> 
    <configuration> 
     <skipTests>false</skipTests> 
     <argLine>${surefireArgLine}</argLine> 
     <excludes> 
     <exclude>**/integration/*.java</exclude> 
     </excludes> 
    </configuration> 
    </plugin> 
    <plugin> 
    <groupId>org.jacoco</groupId> 
    <artifactId>jacoco-maven-plugin</artifactId> 
    <version>0.7.6.201602180812</version> 
    <configuration> 
     <skip>false</skip> 
     <output>file</output> 
     <append>true</append> 
    </configuration> 
    <executions> 
     <execution>

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

     <goals>

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

Вот консольный вывод:

И это все.

UPDATE: Я побежал следующую команду: МВН jacoco: сообщить -X и он сказал что-то интересное:

[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 

Он смотрит на jacoco.exec файл, когда у меня было создать jacoco- ut.exec.

Это немного удивительно, так как файл был создан:

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

Я думаю, мне нужно указать, что имя файла в конфигурации отчета где-то.

UPDATE: После перемещения конфигурации destFile и dataFile, приведенной выше в конфигурации Jacoco, проблема была решена и отчет был создан в каталоге site /.

Полный плагин теперь выглядит следующим образом:

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

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

     </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> 

Хотя плагин определен в элементе плагинов, а не в элементе pluginManagement, чтобы получить отчет я все еще нужно выполнить команду:

mvn jacoco:report 

Я хотел бы отчет будет производиться при выполнении команды:

mvn clean install 

Answer 1

Используйте эту конфигурацию, и у вас не должно возникнуть проблем с созданием сайта с помощью mvn clean install.

Внутри папки сайта будут две разные папки: jacoco, содержащий отчет ваших модульных тестов и jacoco-it, содержащий отчет об интеграционных тестах.

конфигурации JaCoco

Настройка Jacoco выставить переменные конфигурации для интеграции модульных тестов (jacoco.argLine) и интеграционные тесты (jacoco.it.argLine) и сформировать папку с сообщениями интеграций испытаний (jacoco-it):

        </configuration> 
       </execution> 
      </executions> 
     </plugin> 

Отказоустойчивыми конфигурации

 <plugin> 
      <artifactId>maven-failsafe-plugin</artifactId> 
      <executions> 
       <execution> 
        <goals> 
         <goal>integration-test</goal> 
         <goal>verify</goal> 
        </goals> 
        <configuration> 
         <redirectTestOutputToFile>true</redirectTestOutputToFile> 
         <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> 

Взгляните на <argLine>${jacoco.it.argLine}</argLine>. Этот заполнитель заменит все параметры, указанные плагином JaCoco. Он будет содержать переменные конфигурации, необходимые для интеграции JaCoco с вашими интеграционными тестами.

Surefire конфигурации

 <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> 

Опять же, посмотрите на <argLine>${jacoco.argLine}</argLine>. Он будет содержать переменные конфигурации, необходимые для интеграции JaCoco с вашими модульными тестами.
