How to run bitcoin source through sonar

gistfile1.txt

First, you have to download and build the Bitcoin Core
------------------------
1. Clone the bitcoin source code and cd into `bitcoin`

        git clone https://github.com/bitcoin/bitcoin
        cd bitcoin

2.  Build bitcoin-core:

    Configure and build the headless bitcoin binaries as well as the GUI (if Qt is found).

    You can disable the GUI build by passing `--without-gui` to configure.

        ./autogen.sh
        ./configure
        make

Next you have to create a sonar account, perform the scan locally and upload it.
------------------------
3. Navigate to https://sonarcloud.io/projects

4. Click on "Analyse New Project" button

5. Generate a new token

6. Choose "C C++" as the language (this does not work on sonarcloud.io currently, waiting to hear back from sonarcloud 10.02.018). 

NOTE: if you don't add -Dsonar.language=c  ...then the scanner defaults to java. But of course this only scans the c files, missing all the cpp files which is crap.

7. Follow the prompts and download the scanner for your O/S

8. Open your terminal and run:
  /Applications/sonarcubeScanner/build-wrapper-macosx-x86 --out-dir bw-output make clean all
  
  ... wait... then run:
  
  /Applications/sonarcubeScanner/sonar-scanner-3.0.3.778-macosx/bin/sonar-scanner \
  -Dsonar.projectKey=<the project key> \
  -Dsonar.organization=bitcoin \
  -Dsonar.cfamily.build-wrapper-output=bw-output \
  -Dsonar.sources=./src \
  -Dsonar.exclusions=**/*.py \
  -Dsonar.host.url=https://sonarcloud.io \
  -Dsonar.login=<the key they generate> -X

9. View the project at https://sonarcloud.io/dashboard?id=<the project key>

Unfortunately, this is what happens:

That's really worked!!
