从SonarQube的documentation：

  

SonarSource分析器不会运行测试或生成报告。他们只导入预先生成的报告。

Jacoco是一个流行的用于生成Java代码覆盖率的库。

SonarQube提供this guide来创建和导入Jacoco的报告。

这是sonar-project.properties工作文件：

# SONAR CLOUD CONFIGS
sonar.host.url=https://sonarcloud.io
sonar.organization=xxx
sonar.projectKey=xxx
sonar.login=xxx

# SOURCES
sonar.java.source=12
sonar.sources=src/main/java
sonar.java.binaries=target/classes
sonar.sourceEncoding=UTF-8

# EXCLUSIONS
# (exclusion of Lombok-generated stuff comes from the `lombok.config` file)
sonar.coverage.exclusions = **/*Exception.java,**/MySpringBootApplication.java

# TESTS
sonar.coverage.jacoco.xmlReportPaths=target/site/jacoco/jacoco.xml
sonar.junit.reportsPath=target/surefire-reports/TEST-*.xml
sonar.tests=src/test/java

我们有同样的问题。您需要在pom.xml中添加coverage块 可以参考以下示例pom.xml

4.0.0 org.springframework.boot 弹簧启动启动器父母 2.3.3发行 测验 测试应用 0.0.1-快照 测试应用 Spring Boot的演示项目
