Could not find com.android.support:appcompat-v7:23.1.1

I checked out and built the project at https://github.com/kosiara/artoolkit-android-studio-example
I have Android Studio 4.0.2 on Windows 10.
The build error I get is:

I'm afraid I don't understand what is wrong.
I'm not sure what needs to be set to version 23.1.1. I looked in my Android SDK manager under SDK Tools, Android SDK Build-Tools and there is no option for 23.1.1. (Is that even where I should be looking?) I see 23.0.1, 23.0.2 (Installed), 23.0.3. Also the Android SDK Platform 23 is installed.
Do I need to add a custom Site to get the missing 23.1.1 option? I have no idea how to do that or what site it would be, if that's what's required.
I suspect there's likely something not set up correctly about my SDK or Android Studio, but I don't know what to check next.
I see this related question but that question has no answer.
I'd like some help getting this example to build.

That version of that module (appcompat-v7) is not in the JCenter repository.
You have to add google maven using the old way when you're using an old version of Gradle, you are not allowed to use google() on Gradle v1.5.

It says I should increase kotlin version but when I went into the build.gradle of my app, I did not see any kotlin in it. This is the build.gradle of my app
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.6.3'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}

I don't think your issue is related to kotlin version. Looks like either you don't have a proper internet connection and your project its failing to download build tools 3.6.3 or you have "offline mode" enabled for gradle plugin.
If you are sure you have a proper internet connection, check if you have offline mode enabled in
Android Studio File -> Settings -> Build, Execution, Deployment -> Gradle
Or the quickest by just typing offline mode in the Android studio actions.
Hit shift + cmnd + a in Mac or shift + cntrl + a in windows.
Then type "offline mode"
Disable it
Sync gradle and run your proyect again.
This should solve the issue.

You probably have a version mismatch with your RN version and gradle. For ReactNative 0.51, you should use gradle 3.5. But this is not the only problem. Your project is out of date. You probably won't be able to publish your app to Google Play store, because Google introduced new publishing format (App Bundle) and your release apk will be rejected by the Play store. See more here: https://developer.android.com/platform/technology/app-bundle
To make that possible, you need to upgrade to gradle 5.5, and do that with React Native, you'll need to upgrade to 0.60+ version. See how to do that here: https://facebook.github.io/react-native/docs/upgrading
If you get lost upgrading the current project, alternative is to initialize a new project, link dependencies and c/p block-by-block of your code and adjust your code to new versions of libraries you use (if necessary).

Please help me, thanks.

You can try upload your local library (in user/.gradle/caches) to Jenkins server, It 's work for me.

I don't think that run the build with super user rights is a good solution, because it's not seems to be possible to resolve dependencies.
Just a suggestion how to solve it: Gradle has it's own local cache for dependencies and doesn't need to download them on every build. So you may use the same Gradle distribution, which is used by Jenkins, and once build your application manually with su rights, to resolve all dependencies and cache them.
Just to note, by default dependencies with dynamic versions are cached for 24 hours only, as it's said in the official docs, but you can change it as:
configurations.all {
resolutionStrategy.cacheDynamicVersionsFor 10, 'minutes'
resolutionStrategy.cacheChangingModulesFor 4, 'hours'
}

You need to install "Android Support Repository" from the Android SDK manager. (a.k.a extra-android-m2repository if installing from the command line)
**OR**
You need to install "Android Support Library(Obsolete)" from the Android SDK manager.

This issue exists in Android studio Beta versions
The only solution is to use
repositories {
maven {
url 'https://maven.google.com'
}
}
in project gradle file

Installing both Android Support Library and Local Maven Repository for Support Libraries from the Android SDK manager (Extras section) fixed this issue for me.

If you are using Android SDK command line tools, type:
sdkmanager "extras;android;m2repository"
The SDK manager will install the m2 repository

try compile 'com.android.support:multidex:1.0.0'

I fixed it by adding google() in allprojects node on top-level build.gradle file. Here is my top level file for reference
buildscript {
repositories {
jcenter()
mavenLocal()
google()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.0'
}
}
allprojects {
repositories {
jcenter()
google()
}
}
