Wrapper: Error - Unable to execute Java command

conf/wrapper.conf 文件属性配置如下：
wrapper.java.command=%JAVA_HOME%/bin/java

jvm 1 | WrapperSimpleApp: Unable to locate the class org.sonar.application.App: java.lang.UnsupportedClassVersionError: org/sonar/application/App : Unsupported major.minor version 52.0

jdk 版本过低

WrapperSimpleApp: Encountered an error running main: org.sonar.process.MessageException: Unsupported JDBC driver provider: mysql

jvm 1 | WrapperSimpleApp: Encountered an error running main: org.sonar.process.MessageException: Unsupported JDBC driver provider: mysqljvm 1
| org.sonar.process.MessageException: Unsupported JDBC driver provider: mysql

原因是SonarQube 7.9以上版本已不再支持mysql

jvm 1 | WrapperSimpleApp: Encountered an error running main: java.lang.IllegalStateException: SonarQube requires Java 11 to runjvm 1

需要jdk 11

WARN app[][o.e.t.n.Netty4Transport] exception caught on transport layer [[id: 0x146de8cb, L:/127.0.0.1:57099 – R:/127.0.0.1:9001]], closing connection

根据sonar.properties里面的注释，mysql版本不能低于5.6

Sat May 15 20:00:19 CST 2021 WARN: Establishing SSL connection without server’s identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn’t set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to ‘false’. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

需要在连接数据库的url上设置：useSSL=false就可以了。
