用Maven生成JaCoCo代码覆盖率报告

Question

<plugin>
    <groupId>org.jacoco</groupId>
    <artifactId>jacoco-maven-plugin</artifactId>
    <version>${jacoco.version}</version>
    <executions>
      <execution>
        <id>prepare-agent</id>
        <goals>
          <goal>prepare-agent</goal>
        </goals>
      </execution>
      <execution>
        <id>report</id>
        <phase>prepare-package</phase>
        <goals>
          <goal>report</goal>
        </goals>
      </execution>
      <execution>
        <id>post-unit-test</id>
        <phase>test</phase>
        <goals>
          <goal>report</goal>
        </goals>
        <configuration>
          <!-- Sets the path to the file which contains the execution data. -->

          <dataFile>target/jacoco.exec</dataFile>
          <!-- Sets the output directory for the code coverage report. -->
          <outputDirectory>target/my-reports</outputDirectory>
        </configuration>
      </execution>
    </executions>
    <configuration>
      <systemPropertyVariables>
        <jacoco-agent.destfile>target/jacoco.exec</jacoco-agent.destfile>
      </systemPropertyVariables>
  </configuration>
</plugin>

Answer 1

以下配置应该足够了：

<build>
  <plugins>
    <plugin>
      <groupId>org.jacoco</groupId>
      <artifactId>jacoco-maven-plugin</artifactId>
      <version>${jacoco.version}</version>
      <executions>
        <execution>
          <id>prepare-agent</id>
          <goals>
            <goal>prepare-agent</goal>
          </goals>
        </execution>
        <execution>
          <id>report</id>
          <phase>test</phase>
          <goals>
            <goal>report</goal>
          </goals>
        </execution>
      </executions>
    </plugin>
  </plugins>
</build>

然后可以在target/site/jacoco/中找到这些报告

它在您的情况下不起作用的原因：
