SonarQube 5.3 Attemps Starting then Stops

Question

I've looked at SonarQube for quite a while and is now in a position where I would need it where I currently work. To begin with though, I try to install it locally and have it analyze one of our projects before committing it to a server environment. But installing SonarQube has proven to be more troublesome than first assumed.

I went to the SonarQube website to check out the documentation on how to set it up. My current setup is:

Windows 7 64-Bit
JDK 7 Update 79
Microsoft SQL Server 2012

So I went into the SonarQube properties to start setting it up. I got the following settings:

sonar.jdbc.url=jdbc:sqlserver://obscured;databaseName=sonar;integratedSecurity=true
sonar.jdbc.maxActive=60
sonar.jdbc.maxIdle=5
sonar.jdbc.minIdle=2
sonar.jdbc.maxWait=5000
sonar.jdbc.minEvictableIdleTimeMillis=600000
sonar.jdbc.timeBetweenEvictionRunsMillis=30000
sonar.web.host=192.0.0.1
sonar.web.context=/sonar
sonar.web.port=9000

When I try to run StartSonar.bat (as Admin) it gives me this in the sonar.log file:

Error: Could not find or load main class #
<-- Wrapper Stopped

I am not sure why it can't find the main class. I have not done anything to alter the file structure. It has simply been extracted in Documents as it's own folder (C:\Users\smf\Documents\sonarqube-5.3).

On a side-note, I have been unable to use the Windows Service option. I can install the service, but whenever I try and start it, I'm told that the service launched but failed to start.

It's all about the #:

Could not find or load main class #

That's because there is a # that doesn't belong there when the Java process is being launched:

-Xms256m -Xss256k -Djava.net.preferIPv4Stack=true # -XX:+UseParNewGC

And my bet is that this # comes from the following in your sonar.properties file:

sonar.search.javaOpts=-Xmx1G -Xms256m -Xss256k -Djava.net.preferIPv4Stack=true \
#  -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=75 \
#  -XX:+UseCMSInitiatingOccupancyOnly -XX:+HeapDumpOnOutOfMemoryError

i.e. you would have only uncommented the first line, but the trailing \ at the end of that line means that the next lines are not treated as comment but are passed as JVM options, # included.

Two solutions:

remove the trailing \ on the first line
preferred solution: uncomment the two remaining lines
