Build.Gradle Templating

Does anyone know of a way to template build.gradle files as modules are created? Right now the issue I have is that I want to be able to have the module's build.gradle contain only a small amount of information since I'd be setting the shared configuration within the top level build.gradle file. I have a buildSrc folder setup to centralize the versioning as well.
Top-level build.gradle file:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath Deps.tools_gradleandroid
classpath Deps.tools_kotlin
classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:1.7.10'
}
}
subprojects {
afterEvaluate { project ->
if (project.hasProperty('android')) {
android {
buildToolsVersion Config.buildTools
compileSdkVersion Config.compileSdk
defaultConfig {
minSdkVersion Config.minSdk
targetSdkVersion Config.targetSdk
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility Config.javaVersion
targetCompatibility Config.javaVersion
}
kotlinOptions {
jvmTarget = Config.javaVersion.toString()
}
}
}
}
}
A module's expected build.gradle file:
plugins {
id 'com.android.application'
id 'org.jetbrains.kotlin.android'
}
android {
defaultConfig {
applicationId "com.company.expectedmodule"
}
}
dependencies {
implementation Deps.androidx_core
implementation Deps.androidx_appcompat
implementation Deps.androidx_material
testImplementation Deps.testlib_junit
androidTestImplementation Deps.testandroidx_junit
androidTestImplementation Deps.testandroidx_espressocore
}
What the build.gradle file looks like when I create a 'New Module':
plugins {
id 'com.android.application'
id 'org.jetbrains.kotlin.android'
}
android {
compileSdk 32
defaultConfig {
applicationId "com.company.newmodule"
minSdk 21
targetSdk 32
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
jvmTarget = '1.8'
}
}
dependencies {
implementation 'androidx.core:core-ktx:1.7.0'
implementation 'androidx.appcompat:appcompat:1.5.0'
implementation 'com.google.android.material:material:1.6.1'
testImplementation 'junit:junit:4.13.2'
androidTestImplementation 'androidx.test.ext:junit:1.1.3'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
}
EDIT: For sake of simplicity I've moved the dependencies bracket to the top-level build.gradle file and also changed the modules to be libraries instead and reduced the code of a library module to below:
plugins {
id 'com.android.library'
id 'org.jetbrains.kotlin.android'
}
android {
}

recommended way of sharing build logic in Gradle is by using convention plugins. Like in this sample.
Also precompiled script plugins can be used to write plugins in syntax similar to regular build scripts.

Build Error: Dependent features configured but no package ID was set

My Android project has two application modules (i.e. app and user modules). Can I create dependency between them?
When I build the app with by adding the "implementation project(path: ':user')", it prompt me the error message as post title.
I found that I could change the module to "library". I prefer to use application at the moment
build.gradle(app)

Android fail to import library

I am new to Android development and making simple app using Jetpack Compose thesedays.
When I import a library in an empty Jetpack Compose project, the compiler can't find the package path.
import me.aflak.arduino.Arduino
import me.aflak.arduino.ArduinoListener
Error message: Unresolved reference: me
This library works fine for "normal View" project. I already googled but couldn't find a clear answer for it.
I doulble checked that I didn't change any settings but for library include.
I really want to know why it fails to import.
Thanks
Here's the build.gradle (Module)

Add these lines into settings.gradle

repositories {
google()
mavenCentral()
// THESE LINES NEED TO BE ADDED
jcenter()
maven { url "https://jitpack.io" }

How to fix error No signature of method: build_9rfemhg4a5yc2kwb7aemx3270.android() is applicable for argument type

I am trying to add databinding to my app.
But the error I am getting after I enable databinding is this:
No signature of method: build_9rfemhg4a5yc2kwb7aemx3270.android() is applicable for argument types: (build_9rfemhg4a5yc2kwb7aemx3270$_run_closure1) values: [build_9rfemhg4a5yc2kwb7aemx3270$_run_closure1#6e3b0699]
The part that causes the error is:
databinding {
enabled = true
}
Removing this part causes the gradle to build properly. But that way I can't add databinding.
the build gradle is :
plugins {
id 'com.android.application'
id 'kotlin-android'
}
android {
compileSdkVersion 30
buildToolsVersion "30.0.2"
defaultConfig {
applicationId "com.example.aboutme"
minSdkVersion 19
targetSdkVersion 30
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard- rules.pro'
}
}
databinding {
enabled = true
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
jvmTarget = '1.8'
}
}
dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"

testImplementation 'junit:junit:4.+'
androidTestImplementation 'androidx.test.ext:junit:1.1.2'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
}

Found the answer.
data'B'inding not data'b'inding
dataBinding {

}

How to fix this error "ERROR: Could not find method compileOptions()" while trying to usee GeckoView?

I'm trying to create an android app using GeckoView, I use the following link as a reference:
https://mozilla.github.io/geckoview/consumer/docs/geckoview-quick-start
I do everything as it is in the example, but I get the following error:

The compileOptions section should be in the android section.
android {
compileOptions {
...
}
}
