Documentation Generation is disabled - doxygen

Question

I did all that is specified in the tutorial - Doxygen Plugin.
Here is the sonarqube-4.5.1/conf/sonar.propeties file doxygen entries:
# Doxygen
sonar.doxygen.generateDocumentation=enable
sonar.doxygen.deploymentPath=D:\Downloads\sonarqube-4.5.1\web
sonar.doxygen.deploymentUrl=http://localhost:9000/sonar/documentation
The output of the sonarqube runner:
16:07:16.265 INFO - ANALYSIS SUCCESSFUL
16:07:16.266 DEBUG - Post-jobs : org.sonar.plugins.doxygen.DoxygenPostJob#28bda649
16:07:16.266 INFO - Executing post-job class org.sonar.plugins.doxygen.DoxygenPostJob

16:07:16.395 INFO - === DOXYGEN EXECUTION ===
16:07:16.396 INFO - ### Generating configuration ###
16:07:16.427 INFO - ### Generating documentation ###
Also, in the specified \web folder there is a documentation folder which seems to contain the correct doxygen documentation output.
Yet I keep getting this Documentation Generation is disabled. message in the SonarQube web interface:
UPDATE
This is what my sonar-project.properties file contains now ― using a unix-style path:
#Doxygen
sonar.doxygen.generateDocumentation=enable
sonar.doxygen.deploymentPath=/Downloads/sonarqube-4.5.1/web
sonar.doxygen.deploymentUrl=http://localhost:9000/sonar/documentation
The output remains the same, same issue.
What do I need to do in order to see the documentation in the web server interface?
This seems to be a server linkage problem, because the documentation is being generated correctly, at this location: /Downloads/sonarqube-4.5.1/web/documentation.
I have also found this content:

in sonarqube-4.5.1\web\deploy\plugins\index.txt.
It looks like doxygen has a false associated with it. If I try to edit it (to true) and restart the server nothing changes. The file is overwritten at by the sonar-runner.

Answer 1

sonar.doxygen.generateDocumentation is a project property, not a server property. You have to set it in your "sonar-project.properties" file if you run your analysis with the SonarQube Runner or in your pom.xml file if you run the analysis with Maven.

Answer 2

Here is how I solved this:
Stopped the sonar-qube server.
Replaced the old sonar-doxygen-plugin-0.1.jar, from /Downloads/sonarqube-4.5.1/extensions/plugins, with the updated doxygen plugin from here https://github.com/SonarCommunity/sonar-doxygen/releases/download/1.0/sonar-doxygen-plugin-1.0-SNAPSHOT.jar.
Commented out the old configuration entries for doxygen from the project sonar-project.properties file. And replaced them with the follwoing entries:
sonar.doxygen.url=http://localhost:8000/
sonar.doxygen.enable=true
Used a simple python script to post the documentation html on that server (http://localhost:8000/).
Restarted the sonar-qube server.
Run the sonar-runner.bat again.
The documentation is in its place now.
