Publish Java artifact to Maven Local with Gradle

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)

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