How do I publish subproject to Maven with subprojects buildscript gradle version？

I want to publish some subproject to maven by using maven-publish plugin. The current Gradle script looks like this.
apply plugin: 'maven-publish'
group "com.huawei.quickapp"
version "1.0-SNAPSHOT"
publishing {
publications {
publishTask(MavenPublication) {
}
}
repositories {
maven {
url = uri("${rootDir}/local_repo/repos/")
}
}
}
}
static Boolean publishIfNeeded(taskName){
println("name = " + taskName)
def list = ["baselibrary", "corelibrary"]
if (taskName in list) {
return true
}
return false
}
I just want two libraries,core and base to be published. When I submitted the code to the pipeline, the CI suggested that the NDK version did not match, but there was no NDK-related configuration in my code. The upgrade is necessary because only versions greater than 3.6 support the use of From Components.Debug or some other build variable in gradle script.I tried configuring the build script for Subproject separately like this:
buildscript {
ext.kotlin_version = "1.4.21"
repositories {
google()
jcenter()
}
dependencies {
classpath "com.android.tools.build:gradle:3.5.3"
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
subprojects {
buildscript {
ext.kotlin_version = "1.4.21"
repositories {
google()
jcenter()
}
dependencies {
classpath "com.android.tools.build:gradle:4.0.1"
}
}
}
but it still not work. I got this error
Could not get unknown property 'Debug' for SoftwareComponentInternal set of type org.gradle.api.internal.component.DefaultSoftwareComponentContainer.
Is there a way to publish a submodule using the buildScripte of a submodule? thx.

How to add a library to Gradle build in Android Studio project?

I want to add the following library to the Gradle build of my project. The library that I want to add is : signal-protocol-java-2.8.1.jar that I have downloaded. How can I add it in the Gradle build, so that I import the classes included in the .jar it in the java classes that I am developing ?
Here is my build.gradle file :
buildscript {
repositories {
google()
mavenCentral()
jcenter {
content {
includeVersion 'org.jetbrains.trove4j', 'trove4j', '20160824'
includeGroupByRegex "com\\.archinamon.*"
}
}
}
dependencies {
classpath 'com.android.tools.build:gradle:4.0.1'
classpath 'com.google.protobuf:protobuf-gradle-plugin:0.8.14'
classpath "android.arch.navigation:navigation-safe-args-gradle-plugin:1.0.0-alpha09"
}
}
ext {
BUILD_TOOL_VERSION = '30.0.2'
COMPILE_SDK = 30
TARGET_SDK = 30
MINIMUM_SDK = 19
JAVA_VERSION = JavaVersion.VERSION_1_8
}
wrapper {
distributionType = Wrapper.DistributionType.ALL
}
allprojects {
repositories {
google()
jcenter()
}
}
subprojects {
ext.lib_signal_service_version_number = "2.15.3"
ext.lib_signal_service_group_info = "org.whispersystems"
ext.lib_signal_metadata_version = "0.1.2"
if (JavaVersion.current().isJava8Compatible()) {
allprojects {
tasks.withType(Javadoc) {
options.addStringOption('Xdoclint:none', '-quiet')
}
}
}
}
task qa {
group 'Verification'
description 'Quality Assurance. Run before pushing.'
dependsOn ':Signal-Android:testPlayProdReleaseUnitTest',
':Signal-Android:lintPlayProdRelease',
':libsignal-service:test',
':Signal-Android:assemblePlayProdDebug'
}

You have to edit your module-level build.gradle (the one you've posted is project-level). It's typically in the "app" folder of your project. Find there dependencies block and add this line:
dependencies {
implementation fileTree(dir: "libs", include: ["*.jar"])
...
}
Then create a folder "libs" near this gradle file and put your .jar library there. Sync the project with Gradle.

Using Gradle plugin from composite build in root project buildscript

I use Gradle Kotlin DSL and in my project I have separate build-dependencies gradle module which is included in settings.gradle.kts like so:
pluginManagement {
repositories {
google()
jcenter()
gradlePluginPortal()
}
}
includeBuild("build-dependencies")
This module contains empty plugin implementation and Deps object. Its build.gradle.kts below:
repositories {
google()
jcenter()
gradlePluginPortal()
}
plugins {
`kotlin-dsl`
`java-gradle-plugin`
}
gradlePlugin {
plugins.register("com.example.dependencies") {
id = "com.example.dependencies"
implementationClass = "com.example.dependencies.DependenciesPlugin"
}
}
Deps object:
object Deps {
const val buildTools = "com.android.tools.build:gradle:4.1.1"
// more dependencies
}
I want to use this Deps object in all modules by applying the plugin in build.gradle.kts files.
plugins {
id("com.example.dependencies")
}
And it works fine, I can import and use Deps object.
But there is a problem when I want to use it in root projects build.gradle.kts and more precisely in buildscript like so:
buildscript {
repositories {
google()
jcenter()
}
plugins {
id("com.example.dependencies")
}
dependencies {
classpath(com.example.dependencies.Deps.buildTools) // It doesn't work
}
}
Is there any way to use a custom plugin inside buildscript like this or could you suggest something to replace this approach?

I also wonder this. However, I think this is the difference between includeBuild and buildSrc.

How to resolved include module Gradle 6.x?

I'm using Gradle 6.6 and have a project include 3 module: app, utils and config; and gradles file
-app
-utils
-config
---Versions.kt
-build.gradle.kts
-settings.gradle.kts
Versions.kt
class Versions {
val kotlin = "1.3.72"
}
settings.gradle.kts
include("app", "utils", "config")
build.gradle.kts
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath(kotlin(module = "gradle-plugin", version = Versions.kotlin))
}
}
allprojects {
repositories {
google()

}
}
This problem is Versions.kotlin in build.gradle.kts file Unresolved reference, although I include config module in settings.gradle.kts
If you understand my problem, please help me, thanks so much!

Android maven publish plugin is not publishing project dependencies

I have an android project which includes 3 modules ModuleA, ModuleB, ModuleC. ModuleA depends on both ModuleB and ModuleC. I'm trying to publish the ModuleA to a maven repository using android-maven-publish plugin and looks like it is not automatically publishing ModuleB and ModuleC to maven when I run publishToMavenLocal. When I try to use published ModuleA as a dependency in a different project gradle could not resolve ModuleB, ModuleC.
Is there something that I am missing?.
I am using gradle plugin version 3.5.0, gradle version 5.4.1 and mavenPublishVersion 3.6.2.
This is how project's gradle looks like
build.gradle(project)
buildScript {
...
dependencies {
classpath "digital.wup:android-maven-publish:3.6.2"
}
}
allprojects {
apply plugin: "digital.wup.android-maven-publish"
}
and ModuleA's build.gradle
build.gradle(ModuleA)
...
dependencies {
api project(":moduleB")
api project(":moduleC")
}
publishing {
repositories {
...
mavenLocal()
}
publications {
mavenSrcModuleA(MavenPublication) {
from components.android
groupId = "com.example.sdk"
artifactId = "moduleA"
version = "1.0.0"
}
}
}
and ModuleB's build.gradle
build.gradle(ModuleB)
...
publishing {
repositories {
...
mavenLocal()
}
publications {
mavenSrcModuleB(MavenPublication) {
from components.android
groupId = "com.example.sdk"
artifactId = "moduleB"
version = "1.0.0"
}
}
}
and ModuleC's build.gradle
build.gradle(ModuleC)
...
publishing {
repositories {
...
mavenLocal()
}
publications {
mavenSrcModuleC(MavenPublication) {
from components.android
groupId = "com.example.sdk"
artifactId = "moduleC"
version = "1.0.0"
}
}
}
