Publish Java artifact to Maven Local with Gradle - maven

Question

I am facing a problem when trying to install a generated jar into my local Maven Repository. The message error just show me 'task 'publish' is not found'
I am using this Gradle Script:
buildscript {
ext {
springBootVersion = '1.3.2.RELEASE'
}
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
}
}
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'spring-boot'
apply plugin: 'maven-publish'
jar {
baseName = 'mongofoundry'
version = '1.0.0'
}
sourceCompatibility = 1.7
targetCompatibility = 1.7
repositories {
mavenCentral()
}
dependencies {
compile('org.springframework.boot:spring-boot-starter-web')
compile('org.springframework.boot:spring-boot-starter-data-mongodb')
testCompile('org.springframework.boot:spring-boot-starter-test')
}
publishing {
publications {
mavenJava(MavenPublication) {
from components.java
}
}
}
eclipse {
classpath {
containers.remove('org.eclipse.jdt.launching.JRE_CONTAINER')
containers 'org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.7'
}
}
task wrapper(type: Wrapper) {
gradleVersion = '2.9'
}
Do you have some idea Why I am reading that error message?
Thanks.
UPDATED
Running the command as #RaGe mentioned, solved the problem:
gradle publishToMavenLocal

Answer 1

The correct task to publish artifacts to local maven is
gradle publishToMavenLocal

Answer 2

Check Maven locally
For developing and testing it is useful to check library locally
gradle settings for apply plugin: 'com.android.library' not apply plugin: 'java-library'(where you can use it by default)
apply plugin: 'maven-publish'
//simple settings
project.afterEvaluate {
publishing {
publications {
library(MavenPublication) {
//setGroupId groupId
setGroupId "com.company"
//setArtifactId artifactId
setArtifactId "HelloWorld"
version "1.1"
artifact bundleDebugAar
/* add a dependency into generated .pom file
pom.withXml {
def dependenciesNode = asNode().appendNode('dependencies')
def dependencyNode = dependenciesNode.appendNode('dependency')
dependencyNode.appendNode('groupId', 'com.company')
dependencyNode.appendNode('artifactId', 'HelloWorld-core')
dependencyNode.appendNode('version', '1.1')
}
*/
}
}
}
}
to run it using command line or find this command in Gradle tab
./gradlew publishToMavenLocal
Location
artefact will be added into .m2 folder
//Unix
~/.m2
//Windows
C:\Users\<username>\.m2
//For example
/Users/alex/.m2/repository/<library_path>/<version>/<name>.<extension>
build folder
<project_path>/build/outputs/<extension>
other repositories location
~/.gradle/caches/modules-2/files-2.1/<group_id>/<artifact_id>/<version>/<id>
//For example
/Users/alex/.gradle/caches/modules-2/files-2.1/com.company/HelloWorld/1.1/c84ac8bc425dcae087c8abbc9ecdc27fafbb664a
To use it add mavenLocal(). It is important to place it as a first item for prioritise it, which is useful for internal dependencies
buildscript {
repositories {
mavenLocal()
}
allprojects {
repositories {
mavenLocal()
}
}
and
dependencies {
implementation 'com.company:HelloWorld:+'
}
*Also remember if you use a kind of shared.gradle file (via apply from) you should set path which is relevant to project.gradle (not shared.gradle)

Answer 3

This is how I did it with Kotlin DSL (build.gradle.kts) for my Android library:
plugins {
id("maven-publish")
// OR simply
// `maven-publish`
// ...
}
publishing {
repositories {
// Local repository which we can first publish in it to check artifacts
maven {
name = "LocalTestRepo"
url = uri("file://${buildDir}/local-repository")
}
}
publications {
// ...
}
}
You can create all the publications with the following command:
./gradlew publishAllPublicationsToLocalTestRepoRepository
Or just a single publication with this command:
./gradlew publishReleasePublicationToLocalTestRepoRepository
See Gradle documentations: Maven Publish Plugin for more information.

Answer 4

Add maven plugin to your project and then:
gradle clean install

Answer 5

Here is an alternative skeleton for Gradle 7.5.1 with Java 17
build.gradle
plugins {
id 'org.gradle.java'
id 'org.gradle.maven-publish'
}
repositories {
mavenLocal()
mavenCentral()
}
dependencies {
}
java {
toolchain {
languageVersion = JavaLanguageVersion.of(17)
}
withJavadocJar()
withSourcesJar()
}
publishing {
publications {
mavenJava(MavenPublication) {
groupId = 'your-group'
artifactId = 'your-artifact'
version = "0.0.1"
from components.java
}
}
repositories {
mavenLocal()
}
}
Publishing
You can see more details on the publishing steps with --info
./gradlew --info publishToMavenLocal
