Sonar + Jenkins job execution error - jenkins

Question

It's been a week since I tried to deploy this solution locally on my machine and then deploy it to a production server.
However, I faced many difficulties and incomprehension, that is what I did:
Sonar installation via apt-get and launch of it on port 9000 of localhost.
Installation of Jenkins via apt-get and launch of it on port 8080 of localhost.
Download the Sonar plugin for Jenkins.
After trying to running a job, it failed because :
ERROR: Error during SonarQube Scanner execution org.sonarqube.ws.client.HttpException:
The full error stack is:
ERROR: Error during SonarQube Scanner execution

When I searched on the SonarQube logs I saw that :

Caused by: java.io.IOException: The temporary upload location [/root/Documents/sonarqube-6.3.1/temp/tc/work/Tomcat/localhost/ROOT] is not valid

Answer 1

As seen in "The temporary upload location is not valid", make sure that the folder /root/Documents/sonarqube-6.3.1/temp/tc/work/Tomcat/localhost/ROOT
does exist
is 775 by the user running Sonar.
Or (as seen here) you can define the temporary folder to another location
JVM_OPTIONS="-Xrs -Xms256m -Xmx512m -Djava.io.tmpdir=/opt/another/tmp"
See this thread and this thread as examples.
