In some of my Gradle based projects, i use libraries which have to be downloaded from many different Maven Repositories. To get a better overview of all used repos i wanted to group them in a list. Unfortunately it was a bit more complicated then i thought it would be. Because i couldn’t find other blog posts with my approach, i wanted to share it with you. So here is my solution:
This is how you add one repository to your buildscript:
|
1 2 3 |
repositories { maven{url "https://example.org"} } |
When you want to add multiple repositories you have add a new maven{} block per URL, something like this :
|
1 |
maven{url "https://example.org",url "https://example1.org"} |
and that:
|
1 2 3 |
list.each { maven { url it } } |
doesn’t work.
The solution
First create a list in a Gradle(Groovy)
|
1 |
def mavenRepos = ["https://example.org","https://example1.org"] |
I created this method, which you have to add in the buildscript{} block:
|
1 |
ext.buildMaven = { p -> repositories { maven { url p } } } |
Now you can use the method buildMaven() inside the repositories{} block inside a .each{} method of your repo list you want to add :
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
buildscript { ext.buildMaven = { p -> repositories { maven { url p } } } ext.kotlin_version = '1.2.31' ext.ktor_version = '0.9.1' def mavenRepos = ["https://plugins.gradle.org/m2/", "https://dl.bintray.com/kotlin/ktor"] repositories { google() jcenter() mavenCentral() mavenRepos.each { buildMaven(it) } } dependencies { classpath 'com.android.tools.build:gradle:3.1.1' classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" } } |
