我可以让Sonar扫描仪与OpenJDK 8配合使用，但不能与OpenJDK 11配合使用。
使用的Maven命令是：
mvn clean org.jacoco:jacoco-maven-plugin:prepare-agent verify sonar:sonar -Dsonar.analysis.mode=preview -Dsonar.report.export.path=sonar-report.json -P ci
构建失败：

Sonar Scanner是否可以与JDK 11合作？
我终于找到了https://github.com/sonargraph/sonar-sonargraph-integration/issues/14
问题来自SonarQube插件，名为sonar-sonargraph-integration。我从SonarQube服务器上卸载了插件，问题就消失了。
