Answer 1

将 sonar.jacoco.reportPath 属性添加到 pom.xml（第 6 行）时问题得到解决：

<properties>
   <java.version>1.8</java.version>
   <maven.compiler.source>1.8</maven.compiler.source>
   <maven.compiler.target>1.8</maven.compiler.target>
   <!-- this is defined in spring-core-env and fits for multi module project. Scanner fails for single module projects! -->
   <sonar.jacoco.reportPath>${project.basedir}/target/jacoco.exec</sonar.jacoco.reportPath>
</properties>

这可以通过阅读https://wiki.jenkins.io/display/JENKINS/JaCoCo+Plugin的评论找到
