Błąd podczas tworzenia raportu pokrycia kodu przy pomocy JaCoCo

Question

Próbuję dodać generowanie raportu dla pokrycia kodu przy użyciu JaCoCo. Projekt realizowany jest przy użyciu Maven, więc mam jacoco Maven plugin skonfigurowany tak:

  <plugin> 
      <groupId>org.jacoco</groupId> 
      <artifactId>jacoco-maven-plugin</artifactId> 
      <version>${jacoco.maven.plugin.version}</version> 
      <executions> 
       <execution> 
        <id>prepare-agent</id> 
        <goals> 
         <goal>prepare-agent</goal> 
        </goals> 
        <configuration> 
         <destFile>${basedir}/target/coverage-reports/jacoco-unit.exec</destFile> 
        </configuration> 
       </execution> 
       <execution> 
        <id>report</id> 
        <phase>prepare-package</phase> 
        <goals> 
         <goal>report</goal> 
        </goals> 
        <configuration> 
         <dataFile>${basedir}/target/coverage-reports/jacoco-unit.exec</dataFile> 
         <outputDirectory>${basedir}/target/jacoco</outputDirectory> 
        </configuration> 
       </execution> 
      </executions> 
     </plugin> 

A murowany wtyczki tak:

  <plugin> 
      <groupId>org.apache.maven.plugins</groupId> 
      <artifactId>maven-surefire-plugin</artifactId> 
      <version>${maven.surefire.plugin.version}</version> 
      <configuration> 
       <argLine>${argLine} -XX:-UseSplitVerifier</argLine> 
       <printSummary>true</printSummary> 
       <excludes> 
        <exclude>**/selenium/**/*.java</exclude> 
       <excludes> 
      </configuration> 
     </plugin> 

Ale w końcu działa

mvn clean package

ja "Otrzymuję taki błąd:

[ERROR] Failed to execute goal org.jacoco:jacoco-maven-plugin:0.7.5.201505241946:report (report) on project LMS: An error has occurred in JaCoCo Test report generation.

Chodzi o to, że przy innym projekcie to samo działa jak czar. Nie mogłem znaleźć rozwiązania online. Ktoś ma jakieś pomysły?

Korzystanie przełącznik -e otrzymuję następujące błędy:

Answer 1

kiedyś w obliczu tego problemu, jak również. Wydaje się, że jest on powiązany z analizatorem Jacoco, który nie może przeanalizować niektórych zasobów (prawdopodobnie były to submoduły git lub zip/binary w nich). Po prostu zignorowanie tej ścieżki folderu zasobów dla tego zadania naprawiło problem.
