根源：scanner的container网络跟sonarqube server不在一个网络内
解决：--network=host 参数

根源： java中缺少sonar.java.binaries 必选参数
解决：使用mvn compile编译源码，并在sonar-project.properties中添加参数
sonar.java.binaries=target/classes
其他语言请参考https://docs.sonarqube.org/latest/analysis/languages/overview/ 获取必选参数信息。

根源： jvm默认配置太小，内存不足
解决：设置环境变量 SONAR_SCANNER_OPTS="-Xmx512m" 或者更大。
docker的解决方案为
docker run --network=host --rm -e SONAR_HOST_URL="http://localhost:9000" -e SONAR_SCANNER_OPTS="-Xmx1024m" -v "/Documents/github/security/Benchmark:/usr/src" sonarsource/sonar-scanner-cli

根源：server 端ES 内存不足, 因为ES默认的heap size为2GB，而Docker的limit也是2GB。
解决：加大内存，docker Desktop端(Mac 与windows端)需要配置docker的最大内存超过4GB。或者限制ES的Heap size到750MB。

5. # Error during SonarQube Scanner execution ERROR: You must define the following mandatory properties for ‘Unknown’: sonar.projectKey
根源：scanner无法在工程的根目录上找到sonar-project.properties文件，尽管该文件存在，但是docker -v挂在目录时不支持相对路径。
解决：将docker run -v...的运行脚本也放到工程根目录下，将当前目录挂载到/usr/src：
docker run ...
-v "$(pwd):/usr/src" \
sonarsource/sonar-scanner-cli
