Error during Sonar-runner execution, Fail to download libraries from server - sonarqube

Question

I'm trying to install SonarQube Runner.
I am using this versions:
sonarqube-5.1
sonar-runner-dist-2.4
mysql 5.1.63
jdk 1.7.0_79
ubuntu 11.4, 32 bits
I've already configured:
sonar/conf/sonar.properties
sonar-runner/conf/sonar-runner.properties
And created the project configuration file to analyze, in the directory of my project:
sonar-project.properties
The SonarQube is running correctly, I can corroborate doing:
service sonar status
If I run:
sonar-runner -X
I get the following error:
SonarQube Runner 2.4

What do I need to do or change to solve it?
The access.log contains:

Thanks!

Answer 1

I found that the version of Java that was running on the server was 6, and this SonarQube needs Java 7. So, I upgraded the version of java. Then continued giving other errors, but droping the database and regenerating it, it worked correctly.

Answer 2

In my case it was too old SonarQube scanner(runner) version. Update to 4.x should fix the problem. See also https://community.sonarsource.com/t/error-during-sonarqube-scanner-execution-after-upgrade-to-sonarqube-8/17378/2.
