How to resolve "HttpException: Error 413" (SonarQube)

Question

I've recently installed the latest version of Jenkins, SonarQube 6.0 (running on a separate server) and when the Jenkins job attempts to upload sonar scanner results to the SonarQube server, I get the following error:

'ERROR: Error during Sonar runner execution
org.sonar.runner.impl.RunnerException: Unable to execute Sonar
at org.sonar.runner.impl.BatchLauncher$1.delegateExecution(BatchLauncher.java:91)

at org.sonar.runner.Main.main(Main.java:53)
Caused by: org.sonarqube.ws.client.HttpException: Error 413 on http://****`

What could be the cause? An error in the sonar-project properties?

Answer 1

I had the same error where my sonarqube server was behind an nginx proxy.

413 == Request entity too large as @jeroen-heier said.

I applied a change to my nginx configuration like this

server {
  ...
  client_max_body_size 20M;
  ....
}

to allow requests to be 20 megabytes, and that fixed it.
