How to use scm plugin?

[piebe]

I like to use the SCM functionality of sonar, but this does not seem to work.

Setting scmDisabled to false results in

No SCM system was detected. You can use the 'sonar.scm.provider' property to explicitly specify it.

Setting this explicitly:

runnerProperties: {
    'sonar.scm.provider': 'git'
},
scmDisabled: false

results in:

INFO: Missing blame information for the following files:
...

Seems to me this is caused by the fact that sonar analyses takes place in the .tmp directory which, of course, does not contain any version information...

Is there a way to get this to work?
