Incorrect detekt.yaml path resolving for nested modules.

[nikitin-da]

We have following project structure:

app
modules/module1
modules/module2
detekt.yaml

Setting /detekt.yaml as configuration path in Sonar/Kotlin/Detekt results in following error:

Provided path '/…/ca4c5a47ac213f623228/modules/detekt.yaml' does not exist

Because tryFindDetektConfigurationFile looks for file in module directory, then if not found looks on directory above which doesn't work if module is nested deeper.

Ideal solution would be to support "absolute" path that starts with / and do something like:

if (path.startsWith("/")) {
  configFile = File(rootProjectPath, path)
} else {
  configFile = File(baseDir, path)
}

Where rootProjectPath is absolute path to the root of the project.

Yeah your right. I forgot to support absolute paths. As sonar treats each module as the root in a Sensor it is hard to find the config file so I wrote about this limitation in the readme.
Do you might to file a PR for this? :)
