MassDep

Deploy mass depositories easily and consistently across projects

Scenario

Before knowing how to use this plugin, you should have an understanding of its scenes to be used.

That's, imagine you are manging a grand project with multiple modules deployed on a private maven repository, each of which may be dependent on others. You may declare the maven repositories one by one, or better, write a small function, ex.

repositories {
    maven {
        url = uri("https://maven.pkg.github.com/example/Example_base-api")
        credentials {
            username = project.findProperty("gpr.user") ?: GIT_USERNAME
            password = project.findProperty("gpr.key") ?: GIT_TOKEN
        }
    }
    maven {
        url = uri("https://maven.pkg.github.com/example/Example_ui-api")
        credentials {
            username = project.findProperty("gpr.user") ?: GIT_USERNAME
            password = project.findProperty("gpr.key") ?: GIT_TOKEN
        }
    }
    maven {
        url = uri("https://maven.pkg.github.com/example/Example_io-sdk")
        credentials {
            username = project.findProperty("gpr.user") ?: GIT_USERNAME
            password = project.findProperty("gpr.key") ?: GIT_TOKEN
        }
    }
    // ...
}
// otherwise
def addRepository(String name) {
    respositories {
        maven {
            url = uri("https://maven.pkg.github.com/example/Example_${name}")
            credentials {
                username = project.findProperty("gpr.user") ?: GIT_USERNAME
                password = project.findProperty("gpr.key") ?: GIT_TOKEN
            }
        }
    }
}
addRepository("base-api")
// ...

// then add corresponding dependencies
dependencies {
    implementation "com.example.api:base:1.0.0"
    implementation "com.example.sdk:io:1.0.0"
    // ...
}

Perhaps you see the addRepository method is already convenient, but it can be tiring to copy it to other repositories, in this example, base-api, io-sdk and ui-api, let alone of consistence and maintaining afterwards.

Usage

In the previous example, it's easy to see that, the gradle dependency notation, such as com.example.api:base:1.0.0, shares the same pattern as its maven repository, https://maven.pkg.github.com/example/Example_base-api.

Basics

Let's sort out this similarity first.

plugins {
    id 'io.github.zhufucdev.massdep' version '1.2'
}

massDep {
    pattern = "https://maven.pkg.github.com/example/{company}_{artifact}-{product}"
}

Next, it's so easy to define the desired dependencies.

dependencies {
    pack 'com.Example.api:base:1.0.0'
    pack 'com.Example.api:ui:1.0.0'
    pack 'com.Example.sdk:io:1.0.0'
}

The company name is automatically lowercased.

Simplification

You can take a step further by defining the default company, domain and product name.

massDep {
    pattern = "https://maven.pkg.github.com/example/{company}_{artifact}-{product}"
    defaultCompany = "Example"
    defaultDomain = "com"
    defaultProduct = "api"
}

dependencies {
    pack 'base:1.0.0'
    pack 'ui:1.0.0'
    pack '.sdk:io:1.0.0'
}

If you don't need to distinguish the product name, you can merge the other selections into the pattern.

massDep {
    pattern = "https://maven.pkg.github.com/example/Example_{artifact}-api"
}

dependencies {
    pack 'com.example.api:base:1.0.0'
    pack 'com.example.api:ui:1.0.0'
}

Credentials

MassDep will look for key and user properties in the massDep extension first.

massDep {
    pattern = "https://maven.pkg.github.com/example/Example_{artifact}-api"
    user = "some string"
    key = "some string"
}

If not found, properties under the root project will be combed through for gpr.user and gpr.key, meaning you can write them in the gradle.properties file for convenience in VC.

gpr.user=some string
gpr.key=some string

Dependency Configurations

The default configuration is implementation. If you want to declare a dependency with a different config, use the > symbol.

pack 'compileOnly>com.example.api:base:1.0.0'

In addition, you can change the default configuration by changing the plugin configuration.

massDep {
    pattern = "https://maven.pkg.github.com/example/.."
    defaultConfiguration = 'classpath'
}
