How to skip publish artifact to nexus for modules which are not changed?

Help/Discuss
1

I am setting up the CI model for one project.This project is almost having 500 modules approx.We just update the workspace everytime through our CI tool and build modules which are actually changed.We are using gradle to build all modules.My requirement is to publish only those modules which are changed in the current build to nexus snapshot repository.I know there is gradle task to publish the artifacts but only to publish the changed modules to nexus is the requirement.Below is the code which I tried and it is able to identify my requirement but it is publishing to maven local and I need to publish to nexus.Can someone let me know how could I achieve this?

Below is the example.

A
B
C
D
E
F

If there is a change in B and F then I want to publish only B and F modules in nexus and if the change is in A and F then want to publish only A and F module.

Could you please help me to achieve this?

I tried the below code which is very simillar to my goal.Whenever I try to change the value of input it publish and after that it doesn’t .It always up-to-date.But I want to implement resource modification check if there is any change/modification/delete/add in the source code then it will build the source code and publish it otherwise no publish

apply plugin: 'maven-publish'

publishing {
    publications {
        mavenJava(MavenPublication) {
            from components.java
        }
    }
}

task incrementalPublishToMavenLocal(type: IncrementalPublishToMavenLocal) {
  inputDir = file('.')
  publication = project.tasks.getByPath(":${project.name}:publishMavenJavaPublicationToMavenLocal").publication
}

class IncrementalPublishToMavenLocal extends org.gradle.api.publish.maven.tasks.PublishToMavenLocal {
    @InputDirectory
    def File inputDir

    @OutputDirectory
    File generatedFileDir = project.file("${project.buildDir}/libs")

    @TaskAction
    void perform(IncrementalTaskInputs inputs) {
        println 'hello this should be executed ones'
    }
}

task incrementalPublishToMavenLocal(type: IncrementalPublishToMavenLocal) {
  publication = project.tasks.getByPath(":${project.name}:publishMavenJavaPublicationToMavenLocal").publication
}

Hi, Anyone figured out this? I am looking for answer for same questions.
And also, may i know why i don’t have publishMavenPublicationToMavenRepository task?

Always getting an error in below lines.

task incrementalPublishToMavenRepository(type: IncrementalPublishToMavenRepository) {
inputDir = project.file(“${project.buildDir}/libs”)
publication = project.tasks.getByPath(“:${project.name}:publishMavenPublicationToMavenRepository”).publication
repository = project.tasks.getByPath(“:${project.name}:publishMavenPublicationToMavenRepository”).repository
}

You can do this way

apply plugin: 'maven-publish'

publishing {
    publications {
        maven(MavenPublication) {
            groupId 'com.example'
            artifactId 'core'
            version '1.0-SNAPSHOT'
            from components.java
        }
    }
}

publishing {
    repositories {
        maven {
        credentials {
            username "abcedf"
            password "***********"
            }
            // change to point to your repo, e.g. http://my.org/repo
            url "https://repo.test.com/content/repositories/snapshots"
        }
    }
}


task incrementalPublishToMavenRepository(type: IncrementalPublishToMavenRepository) {
  inputDir = file('src')
  publication = project.tasks.getByPath(":${project.name}:publishMavenPublicationToMavenRepository").publication
  repository = project.tasks.getByPath(":${project.name}:publishMavenPublicationToMavenRepository").repository
}

class IncrementalPublishToMavenRepository extends org.gradle.api.publish.maven.tasks.PublishToMavenRepository {
    @InputDirectory
    def File inputDir

    @OutputDirectory
    File generatedFileDir = project.file("${project.buildDir}/libs")

    @TaskAction
    void perform(IncrementalTaskInputs inputs) {
        println 'hello this should be executed ones'
    }
}

Rohit, found the problem. I just removed the :${project.name} in below line and everything working fine after configure the output directory. Thanks for the support.

Below line works fine
publication = project.tasks.getByPath(":publishEARPublicationToMavenRepository").publication
