Full gradle file, or preferably the change that makes the problem happen? This may also not be kotlin related

[Geert]

apply plugin: 'com.android.library'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-kapt'
apply plugin: 'realm-android'
apply plugin: "androidx.navigation.safeargs"

    defaultConfig {

    }

    kotlinOptions {
        jvmTarget = "1.8"

I also added

def nav_version = "2.3.0-alpha01"
classpath "androidx.navigation:navigation-safe-args-gradle-plugin:$nav_version"

to classpath dependencies

[Geert]

And

apply plugin: "androidx.navigation.safeargs.kotlin"

did make no difference since I’m using a 100% kotlin project

[Allan Wang]

Did you have no error before? Is there a delta between that and what you have now

[Geert]

I moved the code from an application to an library.

[Allan Wang]

You can either try cleaning your cache, or find the file that isn’t formatted properly

[Geert]

Yeah I already invalidated caches and restarted the project

[Geert]

The problem seems to be in xmlPullParser. Cannot remind me that I’ll use it.

[Geert]

Already deleted the m2 maven folder, but doesn’t seem to help. It only contained another dependency

[Geert]

Unfortunately it doesnt solve the problem @zhuinden

[wasyl]

Don’t you have any additional whitespace at the beginning of the file with navigation graphs (xml)?

[Allan Wang]

it might be one of your resource files, and not a generated one. As mentioned, ' is fine for gradle files

[Geert]

@Lucas Ł im trying to find them, but not in the navigation or layout folder

[wasyl]

The crash occurs in parseNavigationFile so it does seems like one of the files with nav graph is the culprit

[Geert]

Well the problem seems to be MacOS related. https://stackoverflow.com/a/60035821/4713369

[Geert]

There was a hidden .DS_Store file in the navigation folder…

[wasyl]

Definitely worth reporting. They probably shouldn’t even try to parse non-xml files
