Problem Specifying Jetpack Room Schema Location

I'm in the process of converting my android app from using simple file IO to using a proper database, so I've been going through the tutorials for Android Jetpack's Room. I'm having problems trying to specify the room.schemaLocation argument. My build.gradle file looks like this:
apply plugin: 'com.android.application'
android {
compileSdkVersion 31
buildToolsVersion "29.0.2"
defaultConfig {
applicationId "com.austinweaver.myapp"
minSdkVersion 16
targetSdkVersion 31
multiDexEnabled true
versionCode 13
versionName "2.4.2"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
* javaCompileOptions {
* annotationProcessorOptions {
* arguments += ["room.schemaLocation": "$projectDir/schemas".toString()]
* }
* }
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'androidx.appcompat:appcompat:1.4.0'
implementation 'androidx.constraintlayout:constraintlayout:2.1.2'
implementation 'com.google.android.material:material:1.4.0'
implementation 'androidx.legacy:legacy-support-v4:1.0.0'
implementation 'androidx.preference:preference:1.1.1'
implementation 'com.google.android.gms:play-services-auth:20.0.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.3'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
implementation 'com.google.android.gms:play-services-ads:20.5.0'
implementation 'com.android.support:multidex:1.0.3'
implementation ('io.socket:socket.io-client:2.0.0') {
exclude group: 'org.json', module: 'json'
}
implementation "androidx.room:room-runtime:2.4.0"
annotationProcessor "androidx.room:room-compiler:2.4.0"
androidTestImplementation "androidx.room:room-testing:2.4.0"
}
The block marked with the *s is the issue: without it, my app runs fine but tells me to specify the room.schemaLocation. With that block, the gradle sync works but then the app build fails with the following message:
Unable to find method 'java.nio.file.Path.of(Ljava/lang/String;[Ljava/lang/String;)Ljava/nio/file/Path;'
java.nio.file.Path.of(Ljava/lang/String;[Ljava/lang/String;)Ljava/nio/file/Path;
Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)
Re-download dependencies and sync project (requires network)
The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.
Stop Gradle build processes (requires restart)
Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.
In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.
I've tried restarting Android Studio and tried some scattered solutions I found by trying to google the error message, but all the relevant things I found were deprecated or didn't work.
Let me know if there's any information I should have included here, because I'm not sure what else in my project even relates to this. Thanks for any help!
Edit: my project-level build.gradle:
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:4.1.3'
classpath 'com.google.gms:google-services:4.3.10'
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}

All buildscript {} blocks must appear before any plugins {} blocks in the script in Jitpack

I am trying to publish my android library with jitpack. But getting buildscript {} blocks must appear before any plugins {} blocks error.
I have already referred to this question : Getting 'buildscript {} blocks must appear before any plugins {} blocks' error in jitpack but did not found any solution.
Error:

I am pretty sure that this block is causing the error: (in project level gradle)

I cant move it to app level gradle.

i have the same problem too, i just change the position inside build.gradle project like this:

what should I do to fix this problem?

Open the gradle-wrapper.properties
and replace the version of the gradle with this versin
distributionUrl=https\://services.gradle.org/distributions/gradle-7.1.1-all.zip
then sync the project. Then run the project.
The reason of this issue look that all gradle distributions with 6.* version has that issues with android studio 4.2.2 so using the latest version of gradle fixed the issues

Switching Android module from library to application results in "Unable to resolve dependency for :app#debug/compileClasspath"/

I have an android app I want to import to my project as a module. The module syncs and compiles fine with apply plugin: 'com.android.application' However, there are classes from the module that I want to use in my project. To do this, it seems like I need to switch the gradle for the module to read apply plugin: 'com.android.library' as per this question. However, changing the module from an application to a library results in the following error log:
Unable to resolve dependency for ':app#debug/compileClasspath': Failed to transform file 'OCRTest-release.aar' to match attributes {artifactType=android-exploded-aar} using transform ExtractAarTransform
Unable to resolve dependency for ':app#debugAndroidTest/compileClasspath': Failed to transform file 'OCRTest-release.aar' to match attributes {artifactType=android-exploded-aar} using transform ExtractAarTransform
...
Unable to resolve dependency for ':app#releaseUnitTest/compileClasspath': Failed to transform file 'OCRTest-release.aar' to match attributes {artifactType=android-exploded-aar} using transform ExtractAarTransform
So far I have tried invalidating caches and restarting Android Studio, as that was a common suggestion. I have also seen it suggested to delete the .gradle file altogether. Is that safe to do? Also, the main thing I want to do is be able to use Java classes from the module in my app's activities. If there is a better way to go about doing this, let me know.
Here is the code for my .gradle files.
settings.gradle:
include ':app'
include ':OCRTest'
build.gradle(Project):
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.2'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}

}

Remove the following line from build.gradle(Module:app):
implementation project(path: ':OCRTest', configuration: 'default')
Sync Gradle files.
Replace settings.gradle with this line:
include ':app', ':OCRTest'
Sync Gradle files again.
Now goto Project Structure>Add Module dependency and add module.
Hope this helps :)

ERROR Multiple dex files define Lcom/google/android/gms/location/places/zza;

I am facing this issue from 2 days, still not found any solution.
I tried changing versions of libraries, clean and build project, and invalidate cache etc.
Below is my build.gradle file:
apply plugin: 'com.android.application'

I tried my level best
Please, any help would be appreciated.
Thank you very much for your time and assistance in this matter.

please add this lib to resolve this issue
implementation 'com.android.support:multidex:1.0.3'
also, enable multidex in your application class
#Override
public void onCreate() {
super.onCreate();
MultiDex.install(this);
}

your version are conflict
compile 'com.google.firebase:firebase-messaging:17.0.0'
compile 'com.google.firebase:firebase-core:16.0.0'
compile 'com.google.android.gms:play-services-location:15.0.1'
covert to this lines :
compile 'com.google.firebase:firebase-messaging:17.0.0'
compile 'com.google.firebase:firebase-core:17.0.0'
compile 'com.google.android.gms:play-services-location:17.0.0'

You need to use the same version of Firebase and Google Play Service if you're using google play service plugin below 3.3.0.
If you want to use multiple version of Firebase and Google Play Service (starting from version 15), you need to use google play service plugin 3.3.0. So, change your project build.gradle to:
// 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:3.0.1'
classpath 'com.google.gms:google-services:3.3.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
...
Last, don't forget to always add the following line:
apply plugin: 'com.google.gms.google-services'
to the bottom of your app build.gradle.
