## Usage

### 1. Have a working Gradle build

It is up to you.

### 2. Update your home gradle.properties

This will include flag `IS_JCENTER` (default is "false" - Maven Central, "true" - JCenter), username and password (API Key for JCenter) to upload to the Maven server and so that they are kept local on your machine. The location defaults to `USER_HOME/.gradle/gradle.properties`.

It may also include your signing key id, password, and secret key ring file (for signed uploads). Signing is only necessary if you're putting release builds of your project on Maven Central or JCenter.

```properties
IS_JCENTER = false
NEXUS_USERNAME = vorlonsoft
NEXUS_PASSWORD = $tr0ngP@55w0rd

signing.keyId = ABCDEF12
signing.password = P@55w0rd
signing.secretKeyRingFile = ./secring.gpg
```

#### 2.1. Alternative, use environment variables (optional)

You can modify username and password (API Key for JCenter) from environment variables (useful for CI). To use those environment variables on CI just export them:

```properties
export NEXUS_USERNAME = vorlonsoft
export NEXUS_PASSWORD = $tr0ngP@55w0rd
```

#### 2.2. Other home gradle.properties (optional)

This will include `JCENTER_USERNAME` (default is `NEXUS_USERNAME` value) and `JCENTER_API_KEY` (default is `NEXUS_PASSWORD` value) to upload to the JCentor. Also you can modify `JCENTER_USERNAME` and `JCENTER_API_KEY` from environment variables (useful for CI).

```properties
JCENTER_USERNAME = vorlonsoft
JCENTER_API_KEY = $tr0ngJCenter@P!Key
```

### 3. Create project root gradle.properties

You may already have this file, in which case just edit the original. This file should contain the properties values which are common to all of your sub-projects (if you have any). For instance, here's [AndroidRate's](https://github.com/Vorlonsoft/AndroidRate):

```properties
# GROUP (default is packageName for Android projects, "" for non-Android)
GROUP = com.vorlonsoft
# VERSION_NAME (default is build.gradle versionName for Android projects, "" for non-Android)
VERSION_NAME = 1.2.0-SNAPSHOT

POM_DESCRIPTION = Library for Android applications, which provides rating dialog.
POM_URL = https\://github.com/Vorlonsoft/AndroidRate
POM_LICENCE_NAME = The MIT License (MIT)
POM_LICENCE_URL = https\://opensource.org/licenses/MIT
POM_DEVELOPER_ID = AlexanderLS
POM_DEVELOPER_NAME = Alexander Savin
POM_DEVELOPER_EMAIL = [email protected]
POM_SCM_CONNECTION = scm\:[email protected]\:Vorlonsoft/AndroidRate.git
```

The `VERSION_NAME` value is important. If it contains the keyword `SNAPSHOT` then the build will upload to the snapshot server, if not then to the release server.

#### 3.1. Modify the version name from environment variable (optional)

If there's an environment variable called `VERSION_NAME_EXTRAS`, its value will get appended at the end of `VERSION_NAME`.
This can be very powerful when running from CI. For example, to have one SNAPSHOT per branch, you could

```properties
export VERSION_NAME_EXTRAS = -master-SNAPSHOT
```
in this case it will be uploaded to the snapshot server and indicates it's from the master branch.

### 4. Create gradle.properties in each module

The values in this file are specific to the sub-project (and override those in the root `gradle.properties`). In this example, this is just the name, artifactId and `JAVADOC_BY_DOKKA` (default is "false"):

```properties
POM_ARTIFACT_ID = androidrate
POM_NAME = AndroidRate Library
JAVADOC_BY_DOKKA = false
```

Set `JAVADOC_BY_DOKKA` to "true" to generate documentation by Dokka. Dokka is a documentation engine for Kotlin, it fully supports mixed-language Java/Kotlin projects.

#### 4.1 Other gradle.properties in each module (optional)

You can add `POM_PACKAGING` (default is "aar" for Gradle Android Artifacts and "jar" for Gradle Java Artifacts and Gradle Kotlin Artifacts) and change it's value. Depends on Gradle/Plugins versions this option: 1. Changes `` tag in the generated pom file only; 2. Changes main artifact file extension and `` tag in the generated pom file; 3. Changes main artifact and it's asc file extensions and change `` tag in the generated pom file;

Add `VAR_ARTIFACT` (default is "true") and set it to "true" to generate Gradle Android Artifact var. You'll get both `POM_PACKAGING` value (default is "aar" for Gradle Android Artifacts) and "var" artifacts in your Android library project.

Add `ANDROID_JAR_ARTIFACT` (default is "false") and set it to "true" to generate Gradle Android Artifact jar. You'll get both `POM_PACKAGING` value (default is "aar" for Gradle Android Artifacts) and "jar" artifacts in your Android library project.

Add `ANDROID_JAR_MAIN_CLASS` (example "com.vorlonsoft.android.rate.AppRate", default is "") and set it to `${package}.${main-class-name}` to add "Main-Class" attribute to Android's "var", "jar" and "fatjar" `MANIFEST.MF` files.

Add `FATJAR_ARTIFACT` (default is "false") and set it to "true" to generate fatjar. You'll get both `POM_PACKAGING` value (default is "aar" for Gradle Android Artifacts and "jar" for Gradle Java Artifacts and Gradle Kotlin Artifacts) and "fatjar" artifacts.

Add `APKLIB_ARTIFACT` (default is "false") and set it to "true" to generate Gradle Android Artifact apklib. You'll get both `POM_PACKAGING` value (default is "aar" for Gradle Android Artifacts) and "apklib" artifacts in your Android library project. apklib is a way to bundle an Android library project.

Also you can set `POM_ARTIFACT_URL` (default is `POM_ARTIFACT_ID` value), this is makes to easier to have an artifact with one artifactId but the name on JCenter something else.

### 5. Call the script from each module's build.gradle

Add the following at the end of each `build.gradle` that you wish to upload:

```groovy
apply from: 'https://raw.github.com/Vorlonsoft/GradleMavenPush/master/maven-push.gradle'
```

### 6. Build and Deploy/Install

You can now build and *deploy* on JCenter, Maven Central or Corporate staging/snapshot servers:

```bash
$ gradle deployOnServerRepository
```

Build and *install* on local Maven (~/.m2/repository/):

```bash
$ gradle installOnLocalRepository
```

Build and *deploy* on local Maven (~/.m2/repository/):

```bash
$ gradle deployOnLocalRepository
```

#### 6.1 Inter-module dependency (optional)

If your modules have dependencies on each other (e.g. implementation project(':other_module')), then you should do one of the following for proper POM generation

- **option A**: add to top level `build.gradle`:

```groovy
allprojects {
group = GROUP
version = VERSION_NAME
}
```

- **option B**: add to top level `gradle.properties`:

```properties
group = com.vorlonsoft
version = 1.2.0
```

### Other properties (optional)
