Sonar: You must define the following mandatory properties for unknown not resolved

Question

I'm trying to run SonarQube on a project in java. I configured the sonar properties file and placed it in the project directory. On running the sonar.bat there is an error that asks to define the mandatory parameters. At first I assumed my properties file was wrong, but I've tried everything I can think of.

this is the current properties file

# Required metadata
sonar.projectKey=_newtest2
sonar.projectName=NoSqlDataModeling
sonar.projectVersion=2.0

# Path to the parent source code directory.
# Path is relative to the sonar-project.properties file. Replace "\" by "/" on Windows.
# Since SonarQube 4.2, this property is optional if sonar.modules is set. 
# If not set, SonarQube starts looking for source code from the directory containing 
# the sonar-project.properties file.
sonar.sources=D:/eclipse workspace/NoSqlDataModeling


#Comma-separated paths to directories containing the binary files (directories with class files, in the case of Java).
sonar.binaries=D:/eclipse workspace/NoSqlDataModeling/build/classes

#Comma-separated paths to files with third-party libraries (JAR files in the case of Java). Patterns #can be used.
sonar.libraries=D:/eclipse workspace/NoSqlDataModeling/WebContent/WEB-INF/lib/*.jar

#language used
sonar.language=java

# Encoding of the source code
sonar.sourceEncoding=UTF-8

# Additional parameters
sonar.my.property=value

this is the error message

Should I provide comma separated paths to all the class files and java files? Till what depth do I provide the paths? the different class files are located in build/classes/.../.../<4 different folders that have class files inside them> I change the project key every time as I read it has to be unique.

How to Upload a Project to SonarQube:

1) Startup SonarQube. You should be able to see it if you type localhost:9000 into your browser.

2) In command prompt, cd to the directory of your project

3) Make sure the root folder of your project has “sonar-project.properties” file and that it is configured. If your project doesn’t have the “sonar-project.properties” file, it will get this error= Sonar Setup Undefined Mandatory Properties

My “sonar-project.properties” file for my VendingMachineEmulator app looks like this:

4) In command prompt, now type “C:\sonar-scanner\sonar-scanner-2.6.1\bin\sonar-scanner.bat”. Alternatively, you could’ve also type “C:\sonar-scanner\sonar-scanner-2.6.1\bin\sonar-runner.bat” too. I’m not sure what the difference is. Make sure the directory you are in is still the main folder of your project.

5) Done! Refresh localhost:9000 and check if the project is there.
