Not able to include dependancies in JAR file

Help/Discuss
1

I am working on one gradle project, I want to create two jar file for same package, one containing all the class and dependencies and other with contains only few classes with log4j dependancy. I have written below code in build.gradle

// Applies BrazilGradle plugin then uses it to setup the build script classpath.

/*
 Applies core Gradle plugins, which are ones built into Gradle itself.
*/
plugins {
    // Java for compile and unit test of Java source files. Read more at:
    // https://docs.gradle.org/current/userguide/java_plugin.html
    id 'java'

    id 'com.github.johnrengelman.shadow' version '7.1.2'

    // JaCoCo for coverage metrics and reports of Java source files. Read more at:
    // https://docs.gradle.org/current/userguide/jacoco_plugin.html
    id 'jacoco'
}

repositories {
    maven {
        name = 'Brazil WIRE read-only repository'
        url = uri(wireReadRepositoryUrl)
        allowInsecureProtocol = true
    }
    mavenCentral()
}

// Fat jar that contains all dependencies along with code.

task lambdaJar(type: Jar) {
    destinationDir = file("${project.buildDir}/lib")
    classifier = ""
    archiveName = "AnnouncementDecider.jar"

    from sourceSets.main.output.classesDirs
    include "com/amazon/amazonliveannouncementapplication/LambdaFunction/**"
    include "com/amazon/amazonliveannouncementapplication/AppConfig/**"
    include "com/amazon/amazonliveannouncementapplication/POJO/AnnouncementEventResult.class"

    manifest {
        attributes('Main-Class': 'com.amazon.amazonliveannouncementapplication.LambdaFunction.AnnouncementDecider')
    }
}

// Only build the shadow jars
// jar.enabled = false

task copyConfiguration(type: Copy) {
    from "${project.projectDir}/configuration"
    into "${project.buildDir}"
}

// Copy over config and build shadowJar after completing build
tasks.build.finalizedBy(tasks.copyConfiguration, tasks.shadowJar, tasks.lambdaJar)
// Add release task for pipelines packaging (build fleet)
task release {
}
//Register "release" task in build.gradle. The "release" task is required for the package to be built in https://build.amazon.com/
tasks.release.finalizedBy(tasks.build)

As mentioned in above build.gradle, I wants to created AnnouncementDecider.jar with containing only few classes from directories LambdaFunction, AppConfig and AnnouncementEventResult class itself,

along with this, I want dependency org.apache.logging.log4j:log4j-core:2.20.0 to be part of AnnouncementDecider jar, can someone please help me how can I do so?

I am able to create LiveAnnouncementApp fat jar successfully but not this AnnouncementDecider one.

I have gone through multiple solution over stack over flow but nothing help me like including dependencies with

dependencies {
include(dependency(“org.apache.logging.log4j:log4j-core:2.20.0”))
} in lambda jar and many more.

If you want to build such a bad-practice fat jar, you probably have to use a task of type ShadowJar, not Jar.

3

I also tried to use shadowJar, but AFAIK it is used to zip all the dependencies there in dependancy clause, not able to understand how to include only few dependancies of dependancy clause.

Not the shadowJar task, but a new task of type ShadowJar.
How you need to configure it to only include what you want, you can read in its documentation.
