Add custom Nexus Repository OSS to your Grails 3 Gradle build

After creating Grails 3 plugins and publishing them to your private/public Nexus Repository OSS server, you will want to use them in your projects. To use your custom Grails 3 plugins just add the following closure block to the repositories closure in build.gradle:

	repositories {
	...
	maven {
	credentials {
	username NEXUS_USERNAME
	password NEXUS_PASSWORD
	}
	url 'https://[my.nexus.repo]/repository/releases/'
	}
	}

As with previous examples, NEXUS_USERNAME and NEXUS_PASSWORD are project parameters that you can store in gradle.properties file or pass on the command line.

Publishing Grails 3 plugins to Nexus Repository OSS using Gradle

To publish a Grails 3 plugin to Nexus Repository OSS is extremely simple because the necessary Gradle plugin is already included in the build.gradle file by default. Just add a publishing closure to the build.gradle file and you are ready to push to your private Nexus Repository OSS server.

	publishing {
	repositories {
	maven {
	credentials {
	username NEXUS_USERNAME
	password NEXUS_PASSWORD
	}
	url "http://[my.nexus.repo]/repository/releases/"
	}
	}
	}

As in the Grails application publishing example, the NEXUS_USERNAME and NEXUS_PASSWORD keywords are parameters that you store in gradle.properties and can overwrite with command line parameters, such as

./gradlew -PNEXUS_USERNAME=[your_username] -PNEXUS_PASSWORD=[your_password] publish-plugin

** Edit **

Per Amad's comments, the grailsPublish closure may be required. I modified the attributes in the closure supplied by the create-plugin script as follows:

	// dependencies
	grailsPublish {
	user = 'dspies'
	key = 'key'
	githubSlug = 'foo/bar'
	license {
	name = 'Apache-2.0'
	}
	title = 'My Plugin Name'
	desc = 'My Plugin Description'
	developers = [dspies:'David Spies']
	portalUser = ''
	portalPassword = ''
	}
	// rest of build.gradle

Publishing Grails 3 applications to Nexus Repository OSS using Gradle

To publish a Grails 3 application to Nexus Repository OSS you just need to make a few tweaks to the build.gradle file.  Just add the Gradle maven-publish plugin and a publishing closure to the build.gradle file and you are ready to push to your private Nexus Repository OSS server.

	apply plugin:"maven-publish"
	// Other closure blocks
	publishing {
	publications {
	maven(MavenPublication) {
	from components.java
	}
	}
	repositories {
	maven {
	credentials {
	username NEXUS_USERNAME
