Gradle and Sonar - connection refused error - build

Question

I have configured gradle and sonar plugin:
apply plugin: 'sonar'
// sonar settings - gradle-1.0-milestone-3 2 - check new sonar plugin for milestone 5 release
sonar {
server {
Url = "http://myserver:9000"
}
database {
url="jdbc:mysql://myserver:3306/sonar?useUnicode=true&characterEncoding=utf8"
driverClassName="com.mysql.jdbc.Driver"
username="usrname"
password="pwd"
}
}
I can connect to sonar using web browser.
I can connect to mySQL database using simple java test program.
I have copied mysqlconnector.jar file into GRADLE_HOME/lib
when I run
gradle -debug sonarAnalyze
I am getting:

What could be the problem?

Answer 1

server.url in your code snippet is misspelt; it needs to be a lower case u. Other than that, it could be a wrong URL or wrong network configuration. Or maybe you are using a version of the Sonar server that isn't compatible with the Sonar client library that ships with Gradle 1.0-milestone-3.
By the way, Gradle 1.0-milestone-3 is really old (18 months or so), and a lot has changed since then. I recommend to try with 1.0.
