java - Sonar properties files

Question

I have a project that has the following package structure

src/main/proj
    -com.company.package
        -appName
            -morepackages

        -appVersion2
            -morepackages

sonar-runner.properties
sonarBuild.sh
sonar-runner-project2.properties
sonarBuildProject2.sh

As it stands, with the default properties file i can run the sonar report and it will generate a review for the whole project

sonar.projectKey=KEY
sonar.projectName=PROJNAME
sonar.projectVersion=1.0

sonar.host.url=someurl

#Path for sonar sources
sonar.sources=src/main/java

#Path for libraries
sonar.libraries=target/lib/*.jar

#Path for binaries
sonar.binaries=target/classes

#--------Default database
sonar.jdbc.url=someurl
sonar.jdbc.driver=com.mysql.jdbc.Driver

#----- Global database settings
sonar.jdbc.username=sonar
sonar.jdbc.password=sonar

#----- Default directory layout
sonar.java.source=1.6
sonar.java.target=1.6

sonar.sourceEncoding=UTF-8

Ideally however I would like to separate the two reports so i have one for the original package and one for the appVersion2 package. Now - as mentioned above I have created a separate properties file for each. Should i just point sonar.sources to the respective packages for each job to analyse or is there a better way to do this all in one property file?

Thanks

EDIT

My multi module attempt properties file looks as follows

sonar.projectKey=rootkey
sonar.projectName=rootname
sonar.projectVersion=1.0
sonar.host.url=rooturl
sonar.sources=src/main/java/
sonar.libraries=target/lib/*.jar
sonar.modules=module1,module2
sonar.sourceEncoding=UTF-8

#----- Global database settings
sonar.jdbc.username=user
sonar.jdbc.password=pass

sonar.java.source=1.7
sonar.java.target=1.7


#--------Default database
sonar.jdbc.url=url
sonar.jdbc.driver=com.mysql.jdbc.Driver


module1.sonar.projectName=proja
module2.sonar.projectName=projb

module1.sonar.projectKey=projakey
module2.sonar.projectKey=projbkey

#Path for sonar sources
module1.sonar.sources=src/main/java/app1code
module2.sonar.sources=src/main/java/app2code

#Path for binaries
module1.sonar.binaries=target/classes/app1binaries
module2.sonar.binaries=target/classes/app2binaries

I get an error in the output saying....

Answer 1

You have to specify the projectBaseDir if the module name doesn't match you module directory.

Since both your module are located in ".", you can simply add the following to your sonar-project properties:

module1.sonar.projectBaseDir=.
module2.sonar.projectBaseDir=.

Sonar will handle your modules as components of the project:

EDIT

If both of your modules are located in the same source directory, define the same source folder for both and exclude the unwanted packages with sonar.exclusions:

module1.sonar.sources=src/main/java
module1.sonar.exclusions=app2code/**/*

module2.sonar.sources=src/main/java
module2.sonar.exclusions=app1code/**/*
