Hello people. *Is it possible to have a master config file + another file for custom rules only?*

_Use case_
*More teams* share the *same config*, which is fetched from a shared repo and *ensures every team follows the same rule-set.*
But each team should be able to *extend Detekt* to create *additional rules.*
What is the right way to define a configuration for additional rules only?

_Additional extra info_
I noticed that `detekt.config` accepts multiple files, but I’m unsure how it works. Do they have a particular priority? How could we add more than 1 config file to the Detekt plugin?

Yes you can specify multiple config files and they will get merged.

Thanks, but the original rule-set mustn’t be affected ( rules cannot be overridden ). Is there a priority order?

Also, how to set up more than 1 config to the plugin? I tried to add them comma-separated into `configPaths` but didn’t work :smile:

```detekt {
    // option 1
    config = files("path1", "path2")
    // option 2
    config.from("path1", "path2")
}

tasks.withType(io.gitlab.arturbosch.detekt.Detekt).configureEach {detektTask -&gt;
    // only option 2 available for task level configuration
    config.from("path1, path2")
}```


It’s a FileColleciton, not a list, so gradle handles it in a special way

So basically, given `path1` had `SomeRule: active: true` and `path2` has `SomeRule: active: false` there's no guarantee whether the rule will be active or not, correct?

So, unless I wanna merge the 2 files manually, I guess the only option is not telling the teams that rules can be overridden :smile:

Not sure exactly how the precedence is decided. I’m sure it’s deterministic in some way.

But if you don’t like it, you can always write a task to merge (and optionally, validate) your configs in a way that’s appropriate to you, and use the output of that task as the config for detekt.

Yes, but I wanna limit the required work for now, maybe ad a second step. Thank you.

Also, when I asked about adding both of the config to the Plugin, I mean the IDE plugin :slightly_smiling_face: as the file picker doesn't allow picking multiple files; I tried editing the xml, without success

Oh I see, yeah, not sure on that one. I don’t think the IDE plugin supports custom rules anyways.

There's an option for additional jars, so I believe it does :slightly_smiling_face:

Scratch that, you are correct. It does. I just didn’t configure mine correctly.

The IDE seems to use colons to separate paths in that selection box

That's great! I'm goin to try that in a min! Thanks :smile:

I might be wrong, but seems like the second is the one who wins :smile:

Aka, rules from the second file override rules from the first one.
So I guess I’ll do `files(custom-rules.yml, config.yml)`
