Gradle to add module dependency in Micronaut project

I have three module as shown below
The fete-bird-apigateway depend on common and fete-bird-product depend on both fete-bird-apigateway and common
In the fete-bird-product settings.gradle I have included the code below
rootProject.name = "fete-bird-product"
include 'fete-bird-apigateway' , 'common'
and in the build.gradle of project
dependencies {
implementation project(':common')
}
Error
Caused by: org.gradle.internal.component.NoMatchingConfigurationSelectionException: No matching configuration of project :common was found.
I don't want to create a multi-module build project describe here https://docs.gradle.org/current/userguide/multi_project_builds.html. Each project should build individually and dependent modules should load while building.
How can I achieve this?

Well I found that I had the wrong concept for different module projects.
Assuming all modules are part of the same multi-module build then in fete-bird-apigateway.gradle and service\build.gradle you add:
plugins {
id 'java'
id 'maven-publish'
}
dependencies {
implementation project(':common')
}
However if common, fete-bird-apigateway and service are separate projects and don't share the same root build.gradle you have to publish the common module into a shared repository and use it like any regular dependency. Easiest to do with Maven Local repository.
To publish to the local maven
In fete-bird-apigateway.gradle
publishing {
publications {
maven(MavenPublication) {
groupId = 'org.gradle.sample'
artifactId = 'library'
version = '1.1'
from components.java
}
}
}
Reference - https://docs.gradle.org/current/userguide/declaring_repositories.html
https://docs.gradle.org/current/userguide/publishing_maven.html#gsc.tab=0
In the dependent project add the dependency as regular
repositories {
mavenLocal()
}
implementation("fete.bird:fete-bird-apigateway:0.1")
We need to run the task or gradle command for publish. I am using Intellj so did with below task
We can run the gradle command gradle publishToMavenLocal

How to publish and use gradle plugin with dependencies on local project?

I am creating gradle plugin which has dependency on my other local module. Some of its gradle build look like this:
dependencies {
compile gradleApi()
compile project(":myDependencyProject")
}
publishing {
publications {
maven(MavenPublication) {
groupId = 'org.my.gradle.plugin'
artifactId = 'some-name'
version = '1.0-SNAPSHOT'
from components.java
}
}
}
gradlePlugin {
plugins {
jsonPlugin {
id = 'org.my.gradle.plugin'
implementationClass = 'my.implementation.class'
}
}
}
When I publish my plugin using gradle publishToMavenLocal and after that I try to use that plugin in another project it fails with this error:
FAILURE: Build failed with an exception.
* What went wrong:
A problem occurred configuring project ':my-project'.
> Could not resolve all artifacts for configuration ':my-project:classpath'.
> Could not find org.my.gradle.plugin:myDependencyProject:1.0-SNAPSHOT.
Searched in the following locations: ...
In simple words it could not find dependency for myDependencyProject project. That is why as a next step I tried to create a fat jar and publish it but I have got the same error (the code for gradle plugin was same except I have changed from components java to artifact shadowJar).
Can someone help me how can I publish gradle plugin with its local dependencies and use it in another project ?
Thank you very much for any help.

We ended up using the Gradle shadow plugin to include our module in the published artifact.
One thing that was important to us though, was to only include the local library in it to prevent our end consumer from having 2 copies of some library (such as Kotlin). So we filtered the dependencies
shadowJar {
dependencies {
include(dependency(':your-module-name:'))
}
}

How to specify "pig-0.13.0-h2.jar" dependency in build.gradle?

To specify a Maven dependency in my project, I provide a name, a group id, and a version. This has been enough for every dependency in my project, save one. Pig has multiple jars in the same artifact (not sure if I have the proper nomenclature; I'm still rather new to Maven), but I only need one.
Specifically, I need pig-0.13.0-h2.jar. However, when I provide the dependency
compile "org.apache.pig:pig:0.13.0"
in my build.gradle, only pig-0.13.0.jar, pig-0.13.0-sources.jar, and pig-0.13.0.pom are downloaded. I need the "*-h2.jar", because that's the correct one to work with my version of Hadoop.
Is there a way to tell Gradle (and, generally, Maven or whatever) that my compile dependency requires this exact jar, and that only this one should be included in the classpath?

What you need is to specify the classifier. The following script will do the job:
apply plugin: 'java'
repositories {
mavenCentral()
}
dependencies {
compile "org.apache.pig:pig:0.13.0:h2"
}
task copyDeps(type: Copy) {
from configurations.compile
into 'deps'
}

Is there Gradle "dependencies " task for buildScript dependencies?

One can run gradlew dependencies to learn about dependencies of module tasks. It there a way to find transitive dependencies of buildscript dependencies?
Example:
classpath 'com.android.tools.build:gradle:1.0.0' depends directly on:
com.android.tools.build builder
com.android.tools.lint lint
net.sf.proguard proguard-gradle
tools.base project-test-lib
As can be seen on MVNRepository. But this artifacts have their own dependencies. Is there and way to find those out without manually traversing whole dependency tree?
As a clarification, the classpath I'm talking about is defined by:
buildscript {
repositories {}
dependencies { .... }
}

Beginning with Gradle 2.10 you can now get information on buildscript dependencies via
gradle buildEnvironment
With older versions you'll have to explicitly define a task of type DependencyReportTask configured with your build script configuration.
task buildscriptDependencies(type: DependencyReportTask) {
configurations = [buildscript.configurations.classpath]
}

I think you're looking for Gradle's DependencyInsightReportTask

You can use this command:
gradle dependencyInsight --dependency gradle
There is awesome tutorial by Udacity, Gradle for Android, but you can watch this video for more explanation.

Configuring Gradle project to depend on lwjgl

How do I configure build.gradle to depend on LWJGL?
I'm new to Gradle, and how to configure library dependencies is clear as mud to me.
It's my understanding is that one can specify library dependencies for Gradle to download rather than checking them in to source control, but any sort of help with configuring things would be appreciated.
(I don't know any Ivy or Maven.)

I think what you want is to have lwjgl in your build classpath and resolve it automatically right?
try this snippet:
plugins {
id "java"
}
repositories{
maven {
url = "http://adterrasperaspera.com/lwjgl"
}
}
dependencies{
implementation "org.lwjgl:lwjgl:2.6"
implementation "org.lwjgl:lwjgl-util:2.6"
}
This snippet above defines a maven repository which contains the lwjgl libs and defines two compile dependencies to your project.
