Sonar和Jacoco:由于没有类文件，因此无法对项目覆盖范围进行JaCoCo分析

我使用Jacoco，Sonar，Maven报告单元测试范围，这是一个springboot项目，请查看我的项目架构，如下所示:

I use Jacoco, Sonar, Maven to report unit test coverage, this is a springboot project and please see my project arch as below:

web
 |-src/test/java --unit test classes
 |-target/
 |-pom.xml
service
 |-pom.xml
pom.xml
target
 |-sonar
 |-jacoco.exec

我在父级pom.xml中的Maven配置:

My maven config in parent pom.xml:

<plugin>
                <groupId>org.jacoco</groupId>
                <artifactId>jacoco-maven-plugin</artifactId>
                <version>0.7.8</version>
                <configuration>
                    <destFile>${project.basedir}/../target/jacoco.exec</destFile>
                    <append>true</append>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>prepare-agent</goal>
                            <goal>report</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

web/pom.xml:

<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>3.0.0-M4</version>
                <configuration>
                    <skipTests>false</skipTests>
                    <redirectTestOutputToFile>true</redirectTestOutputToFile>
                    <testFailureIgnore>true</testFailureIgnore>
                    <argLine>${argLine}</argLine>
                </configuration>
                <dependencies>
                    <dependency>
                        <groupId>org.apache.maven.surefire</groupId>
                        <artifactId>surefire-junit4</artifactId>
                        <version>3.0.0-M4</version>
                    </dependency>
                </dependencies>
            </plugin>

第1步:运行mvn clean org.jacoco:jacoco-maven-plugin:0.7.8:prepare-agent package -Dmaven.test.failure.ignore=true -q

文件jacoco.exec是在文件夹target/jacoco.exec

第2步:在cmd下运行:

mvn sonar:sonar -Dsonar.projectKey="projectName" -Dsonar.login={key} -Dsonar.host.url=http://ip:port -Dsonar.jdbc.url=jdbc:postgresql://ip:port/sonar -Dsonar.java.binaries=target/sonar

声纳文件夹已生成

sonar
 |-.sonar_lock
 |-projectName.pdf
 |-report-task.txt

我检查了projectName.pdf，存在声纳分析，但测试覆盖率是0，只有单位测试计数正确，然后我打开Sonarqube，发现测试覆盖率也为0.

I checked projectName.pdf,sonar analysis was there but test coverage was 0, only unit test count is correct, then i open Sonarqube find test coverage also 0.

最后，我检查了声纳记录并发现以下记录:No Jacoco...

Finally, i checked sonar log and found below log: No Jacoco...

mvn sonar:sonar日志:

[INFO] Sensor JaCoCoSensor [java]
[WARNING] Property 'sonar.jacoco.reportPaths' is deprecated (JaCoCo binary format). 'sonar.coverage.jacoco.xmlReportPaths' should be used instead (JaCoCo XML format).
[INFO] No JaCoCo analysis of project coverage can be done since there are no class files.
[INFO] Sensor JaCoCoSensor [java] (done) | time=1ms
[INFO] Sensor JavaXmlSensor [java]

问题 :

1. 为什么声纳找不到Jacoco类文件，但找到了jacoco.exec 或其他文件.
2. 如何在Sonar中生成单元测试范围.

1. Why sonar couldn't find Jacoco class files, does it find jacoco.exec or other file.
2. How to genetate unit test coverage in Sonar.

谢谢！
