Multiple configuration files are not supported

[marco-eckstein]

detekt supports multiple configuration files, but the plugin only supports one. I have split my detekt configuration into multiple files: one shared across all projects and one project-specific. So, I cannot use the plugin.

Yes, project specific Detekt config is a must.
Just like Lint and code style are project specific.

Multiple configuration files are supported by using a path separator char like

Unfortunately the file chooser for the config file does not support choosing multiple files for now (PRs welcome).

Since the file path separator is Windows/Linux specific (for Windows a semicolon and for Linux a colon must be used), this causes a problem, if we would like to commit the file .idea/detekt.xml in Git (even if the folder .idea is Git-ignored) to share the configuration of the Detekt plugin (in addition to the Detekt rules).

The cause seems to be path.trim().split(File.pathSeparator) in ProjectUtils.extractPaths. Could this be changed to a way which works for both operating systems?

(Only the colon/semicolon difference causes problems, using slash on Windows systems is not a problem.)
