How to scan code recursively in sonarqube - continuous-integration

Question

I have some code in different folders like folder a, folder b,folder c....and all these three folders are in folder name "sonar". if I want to scan all these folders at a time using sonarqube how can I do it. will it be fine if I keep sonar-project.properties file in folder sonar? or do I need to keep sonar-project.properties in all the folders like in folder a, folder b, and folder c individiually

Answer 1

Usually properties should be there for every folder for making analysis on every folder.
You can also try the following approach if it suits your needs and if it is not a big learning curve:
Prerequisites:
ANT Knowledge
Sonar API
Advantages:
1. Single/Central approach for every code analysis
2. Can avoid sonar.properties for every project/source folder
In this approach, write an ANT script that accepts dynamic parameters
Sample:
<target name="setsonarproperties" description="Setting the sonar properties">
<property name="sonar.projectVersion" value="${projectVersion}" />
<property name="sonar.projectKey" value="${targetProduct}_${projectVersion}" />
<property name="sonar.projectName" value="${targetProduct}" />
<property name="sonar.host.url" value="${hostUrl}" />
<property name="sonar.login" value="${hostUserName}" />
<property name="sonar.password" value="${hostPassword}" />
<loadfile property="textFile" srcfile="${buildOrder}" />
<for param="line" list="${textFile}" delimiter="${line.separator}">
<sequential>
<echo message="#{line}" />
<copy todir="${sourcePath}/sonarsources/#{line}">
<fileset dir="${sourcePath}/#{line}">
</fileset>
</copy>
</sequential>
</for>
</target>
Next also set the sonar user name and password details:
Run analyser:
<target name="sonar" depends="setsonarproperties" description="executing sonar">
<taskdef uri="antlib:org.sonar.ant" resource="org/sonar/ant/antlib.xml">
<!-- Update the following line, or put the "sonar-ant-task-*.jar" file
in your "$HOME/.ant/lib" folder -->
</taskdef>
<sonar:sonar />
</target>
