The main branch has no lines of code. When sonar-scanner is executed command line on Mac

SonarQube Server / Community Build
,

Hello Geeks,
kindly help me, as I have already invested my 15 days.

Version Info:
SonarQube: 8.2, SonarQube Scanner: 4.2.0.1873, Gradle : 6.3, Java: 11.0.3 (64 bit) Oracle, Database: Postgres, OS: Mac OS X 10.14.4 x86_64

What I am trying to achieve:
I have a code base setup on my local machine.
I need to scan this code and get the report, if any blocker/critical… etc. are there.

What I have done so far:

I have created a project on sonarqube. Downloaded the gradle and Android Studio. Build the project using gradle build. Downloaded sonar-scanner.

My SonarQube server is up and running and it shows Quality Gate as Passed and when I click on Overview, then i got warning as "The main branch has no lines of code."

And when I run sonar-scanner, I get attached scan.txt (22.9 KB) logs

I execute below sonar-scanner command:
**sonar-scanner -X -Dsonar.projectKey=Project_Android -Dsonar.sources=. -Dsonar.host.url=http://localhost:9000/sonarqube **

Kindly let me know, in case any specific file is needed.

Hi there.

It looks like you’re somehow only analyzing .class files by exceuting analysis from the /Users/mac/git/project-android/target/classes/com/ directory.

21:45:21.123 DEBUG: 'MainActivity.class' indexed with language 'null'

SonarQube scans source code, not compiled classes. And in fact, there’s a specific scanner for Gradle, the SonarScanner for Gradle, which should ensure you don’t have to do much manual configuration or guessing.

Hi Colin,

In that case if I scan for source code, it says to provide compiled class.

org.sonar.java.AnalysisException: Please provide compiled classes of your project with sonar.java.binaries property

And funny enough, the compiled classes are what you seem to have been trying to scan in your first post. :wink:

sonar.java.binaries will automatically be set the scanner for Gradle, or you can try manually providing a value. This gets messy quickly if you have more than one module.

From the Java documentation

Key Value
sonar.java.binaries (required) Comma-separated paths to directories containing the compiled bytecode files corresponding to your source files.

So in summary – you scan the source code – but also supply the compileid bytecode (through the sonar.java.binaries analysis parameter).

How about you try the Scanner for Gradle?

When tried with -Dsonar.java.binaries=/Users⁩/⁨mac/⁨git⁩/⁨Project_Android/target⁩/classes/com/app/bin

ERROR: Invalid value for sonar.java.binaries

6

For the third time, I’m going to suggest using the Scanner for Gradle, where this gets automatically configured.

Hi Colin,

My issue is resolved, fyi, I was already using Scanner for Gradle, the issue was in my properties file there was junk character in my path, after removing that it is successful.
