Permanently add a plugin to Gradle

Question

I use a third-party Gradle plugin in a lot of projects and would like to add this plugin permanently to my gradle installation. Currently I need to add the plugin to each build.gradle like so: ``` buildscript { repositories { jcenter() } dependencies { classpath "com.github.dcendents:android-maven-plugin:1.2" } } ``` Is there a way to add this plugin to my Gradle installation so that I don't need to include it in every build file? I do realise it might not be the best practice and can result in unreproducible builds.

Accepted Answer

This is a hack and not a solution

Here is now an updated version which is also able to apply plugins and add maven repositories. Testet with gradle 2.10.

Add this Plugin to your .gradle/init.gradle:

```
apply plugin:AddDepPlugin

class AddDepPlugin  implements Plugin<Gradle> {
    def addDeps = [
        "org.ensime.gradle": "gradle.plugin.net.coacoas.gradle:ensime-gradle:0.2.2",
        "com.github.dcendents.android-maven": "com.github.dcendents:android-maven-plugin:1.2"] 
    def addRepos = ["https://plugins.gradle.org/m2/"]
    void apply(Gradle gradle) {
        def add = 0
        gradle.allprojects { project ->
            plugins.whenPluginAdded { t ->
                if (++add == 1) {
                    project.getBuildScriptSource()
                    def bs = project.getBuildscript()
                    bs.getDependencies()
                    def repo = bs.getRepositories()
                    def ccf = bs.class.getDeclaredField("classpathConfiguration")
                    ccf.setAccessible(true)
                    def cc = ccf.get(bs)
                    addDeps.each { k,v-> cc.dependencies.add(project.dependencies.create(v))}
                    addRepos.each { k-> repo.maven { -> setUrl(k) } }
                }
                if (add == 8)
                    addDeps.each { k,v ->
                        if (!k.startsWith("x")) project.apply([plugin: k])
                    }
            }
        }
    }
}
```
