Gradle Error when using maven publishing task - gradle

Question

I am using Gradle version 6.7.1, Currently, in my application I facing an issue with the maven publishing task.
We have kept the publishing task in the central location Gradle file named ( nexusgradle-1.0.5.gradle) and importing it via apply from
the content of the central location Gradle (nexusgradle-1.0.5.gradle) is the below which contain the information of nexus repo for snapshot and release along with user credentials for pushing artefacts to nexus.
apply plugin: 'maven-publish'
publishing {
publications {
mavenJava(MavenPublication) {
from components.web
}
}
repositories {
maven {
credentials {
username 'uploader'
password 'uploaderpassword'
}
println 'A message which is logged at QUIET level'
name 'Nexus_Repo'
def releasesRepoUrl = 'http://<hostname>/repository/<maven-releases>/'
def snapshotsRepoUrl = 'http://<hostname>/repository/<maven-snapshots>/'
url = project.version.endsWith('SNAPSHOT') ? snapshotsRepoUrl : releasesRepoUrl
}
}
}
The application Gradle ( child Gradle file) looks like the one below
import org.apache.tools.ant.filters.ReplaceTokens
plugins {
id 'war'
// Add git release plugin for versioning snaphots and release builds
id 'pl.allegro.tech.build.axion-release' version '1.10.1'
id 'org.springframework.boot' version '2.1.4.RELEASE'
// Add Git properties plugin.
id 'com.gorylenko.gradle-git-properties' version '2.2.0'
id 'jacoco'
}
// apply from center location
apply from :'http://<hostaname>/repository/thirdparty/com/mf/nexusgradle/1.0.5/nexusgradle-1.0.5.gradle'
repositories {
maven {
url = 'http://<hostname>/repository/groupRepo/'
}
jcenter()
}
test {
testLogging.showStandardStreams = true
maxParallelForks = 3
ignoreFailures = true // to skip test Failures
testLogging { //logging the test
exceptionFormat = 'full'
events "passed", "skipped", "failed"
}
}
jacoco {
toolVersion = '0.8.3'
}
jacocoTestReport {
dependsOn test // tests are required to run before generating the report
reports {
xml.enabled true //enabling for generate xml for to capture data in sonarqube server
}
}
// Customize Git properties plugin.
gitProperties {
// Change date format in git.properties file.
dateFormat = "yyyy-MM-dd HH:mm:ssZ"
dateFormatTimeZone = 'GMT'
}
dependencies {
implementation 'org.springframework.boot:spring-boot:2.1.4.RELEASE'
// mutliple import below
}
sourceCompatibility = '1.8'
targetCompatibility = '1.8'
scmVersion {
repository {
directory = project.rootProject.file('.')
}
}
group = 'com.package'
description = 'appname'
project.version = scmVersion.version
project.ext.timestamp = new Date().format("dd/MM/yyyy HH:mm:ss")
processResources {
filter ReplaceTokens, tokens:[BUILD_VERSION: project.version, BUILD_TIMESTAMP: project.ext.timestamp]
}
tasks.withType(JavaCompile) {
options.encoding = 'UTF-8'
}
war {
enabled = true
}
springBoot {
buildInfo()
}
bootWar {
archiveClassifier = 'boot'
mainClassName = 'com.package.appname.SpringBootRunner'
}
when I run the Gradle command for publishing
gradlew clean build publish
The task will fail as the publishing task will try to push artefacts of the snapshot to the release repo instead of the snapshot repo.

* What went wrong:
Execution failed for task ':publishMavenJavaPublicationToNexus_RepoRepository'.

But if I remove the apply from: item and bring the Publishing task to the application Gradle ( child Gradle file) file it will work fine, the build artefact is pushed to snapshot repo without any issue.

Can someone guide me, what mistake I am making when putting the maven publishing task in a parent Gradle file? why child Gradle cant resolve values from parent properly

Answer 1

I found a way to fix it by updating the content of the central Gradle /parent file (nexusgradle-1.0.5.gradle) by adding
afterEvaluate
with the modification, it worked fine.
Is it the correct approach? or is there any better way to do it?
apply plugin: 'maven-publish'
afterEvaluate {project ->
publishing {
publications {
mavenJava(MavenPublication) {
from components.web
}
}
repositories {
maven {
credentials {
username 'uploader'
password 'uploaderpassword!'
}
name 'Nexus_Repo'
def releasesRepoUrl = 'http://<hostname>/repository/<maven-releases>/'
def snapshotsRepoUrl = 'http://<hostname>/repository/<maven-snapshots>/'
url = project.version.endsWith('SNAPSHOT') ? snapshotsRepoUrl : releasesRepoUrl
}
}
}
}
