Environment
• OS: Linux
• IDE: CLion 2026.1.1
• SonarQube for IDE plugin: 12.2.2.84629
• Language: C/C++
• Connected mode: Yes
• SonarQube Server: on prem
• Project type: CMake, out-of-source build
• Compiler: Texas Instruments armcl
• CFamily analysis configured with compile_commands.json
Description
SonarQube for IDE fails to analyze C/C++ files in CLion. The files exist on disk and are part of the CMake build/compilation database, but the plugin reports them as missing:
File to analyze was not found in the file system
After that, the analysis starts with an empty inputFiles list and immediately exits with No file to analyze.
This happens consistently for multiple files.

Important details
The original project path contains @:
/home/ragnar.margus@milrem.lan/git/embedded_control_units
The log uses URI-encoded %40:
/home/ragnar.margus%40milrem.lan/…
This initially suggested URI/path decoding issues. To rule that out, I created and opened a clean copy under:
/tmp/embedded_control_units-sonarlint
Then configured:
sonar.cfamily.compile-commands=/tmp/embedded_control_units-sonarlint/build/compile_commands.json
The same problem persisted:
baseDir: /tmp/embedded_control_units-sonarlint
extraProperties: {
sonar.cfamily.compile-commands=/tmp/embedded_control_units-sonarlint/build/compile_commands.json,
sonar.cfamily.build-wrapper-content={“version”:0,“captures”:}
}
inputFiles: [
]
No file to analyze
And for an existing file:
File to analyze was not found in the file system:
file:///tmp/embedded_control_units-sonarlint/ttc/electrical/app/main.cpp
Verification
The file exists:
ls -l /tmp/embedded_control_units-sonarlint/ttc/electrical/app/main.cpp
The file is also present in the compilation database:
rg ‘ttc/electrical/app/main.cpp’ /tmp/embedded_control_units-sonarlint/build/compile_commands.json
The project builds successfully in CLion:
Build | electrical | config-TTC500-Debug
/tmp/embedded_control_units-sonarlint/build
[258/258] Linking CXX executable /tmp/embedded_control_units-sonarlint/artifacts/Debug/electrical/electrical.out
Build finished
Expected behavior
SonarQube for IDE should resolve the file URI, include the opened file in inputFiles, and analyze it using the configured compile_commands.json.
Actual behavior
SonarQube for IDE reports the existing file as not found, filters it out, sends an empty inputFiles list, and performs no analysis.
Related issues
This looks similar to previously reported SonarQube for IDE file/root resolution issues where valid files are filtered out before analysis:
Question
Is this a known CLion/Linux/C++ issue in SonarQube for IDE? Is there any additional logging I can enable to diagnose why the backend considers an existing file URI missing?
