The SonarQube Post-build Action is deprecated - jenkins

Question

Using Jenkins 1.642.2 for code analysis with SonarQube 5.6.1 for all my maven projects.
When I use maven goal sonar:sonar they take more time to analyse files (more than 7 seconds by file) :
[INFO] Sensor SCM Sensor
[INFO] SCM provider for this project is: svn
[INFO] 1079 files to be analyzed
[INFO]
[INFO] 2/1079 files analyzed
[INFO] 3/1079 files analyzed
[INFO] 4/1079 files analyzed
[INFO] 5/1079 files analyzed
When I use the SonarQube Scanner with this config :
then i have this error :
WARN: Property 'sonar.jdbc.url' is not supported any more. It will be ignored. There is no longer any DB connection to the SQ database.
WARN: Property 'sonar.jdbc.username' is not supported any more. It will be ignored. There is no longer any DB connection to the SQ database.
WARN: Property 'sonar.jdbc.password' is not supported any more. It will be ignored. There is no longer any DB connection to the SQ database.

Any idea to solve this problem because i have a problem to understand the new sonarqube use
i must make a sonar-project.properties file for the maven project?

You can and should still analyze with Maven, using a Build Step. As stated in the docs, you should first "Enable injection of SonarQube server configuration" at the global configuration level, and then in your build enable the Build Environment Option "Prepare SonarQube Scanner environment". Then you can set your Maven goal to the following:
$SONAR_MAVEN_GOAL -Dsonar.host.url=$SONAR_HOST_URL -Dsonar.login=$SONAR_AUTH_TOKEN
