• steps to reproduce:
  just run sonar-scanner on a C project built with build-wrapper

• potential workaround

  1. use a debian/ubuntu based image
  2. download the scanner zip file
  3. set the JRE_PATH pointing at zip’s jre

the error message does not help to determine what exactly is missing.
But it seems the alpine image is either missing a java library OR a system tool is missing, but overall.

Hi @mvk ,

there is a warning on the github project and on the docker bup page about that:

Warning: These Docker images are not compatible with C/C++/Objective-C projects.

you need to natively run the scanner with build wrapper
