use
sonar.java.libraries=D:\\env\\mavenRepoparamter bacause I metioned in my another topic: Sonar scanner can’t use Java custome rule
First I use sonar-java-plugin with version: sonar-java-plugin-5.13.1.18282.jar . In this sonarjava version, scanner scan my project takes 2-3 minutes.
But I encountered problems when I want to get collection generics : List<UserAddDTO> , there are no List<Type> typeArguments() method in class org.sonar.plugins.java.api.semantic.Type interface in version 5.13.1.18282, so I had no choice but upgrade the sonarjava version greater than 6.3.x to use typeArguments() method. At last , I take the version: 6.15.1.26025
In sonar-java-plugin-6.15.1.26025.jar version, scan the same project whth same paramter, it takes 30 minutes to finished . After I compared the debug log, I find with >6.3.x version, every file takes > 3s .

After I realized this, I change the sonarjava version from 6.3.x - 6.15.x , it has same problem.
Then I rollback the version to sonar-java-plugin-5.13.1.18282.jar, scan same project only takes 2-3 minuts.
I don’t know why, In this topic Sonar Scanner taking too long for analyzing,
Ann said MMF-1870 89 - SonarJava 6.3: improve performance . But in my case , It is not improve performance, but greatly reduced.
