Using gradle project variable in buildscript scope - gradle

Question

There is a similar question here Access project extra properties in buildscript closure
but i found a "workaround" which does not look like the optimum
I have a multi gradle project - im declaring the repository in the main gradle file
using
subprojects {
repostiories {
maven {..}
}
}
now i also have to set these for the build script because im using a plugin !
so again buildscript { repositories ...
Now instead of pasting the URLs twice i wanted to use a property - as i figured project.ext properties are not set during the buildscript stage thus i put them
in my gradle.settings file
i couldnt set rootProject.ext.xx settings so i had to use
gradle.ext {
mavenURLs = [ companyURL1, companyURL2 ... etc]
}
Now i could use gradle.ext.mavenURLs in my build.gradle file
Is there a better way ?
Is there a way to set the buildscript and dependency repositories for all project in one block without repeating once for buildscript and once for the dependency ?

Answer 1

def repoClosure = { RepositoryHandler repoHandler ->
repoHandler.mavenLocal()
repoHandler.mavenCentral()
['http://mycompany/repo1', 'http://mycompany/repo2'].each { mavenURL ->
repoHandler.maven {
url mavenURL
credentials {
username 'foo'
password 'bar'
}
}
}
}
project.with {
allprojects {
repoClosure(buildscript.repositories)
repoClosure(repositories)
}
}

Answer 2

Simply create my-repositories.gradle file, with content like:
def repoClosure = {
maven {
url uri("${rootProject.rootDir}/offline-repository")
}
google()
mavenCentral()
['http://mycompany/repo1', 'http://mycompany/repo2'].each { mavenURL ->
maven {
url mavenURL
credentials {
username 'my-name'
password 'my-password'
}
}
}
}
project.with {
allprojects {
buildscript {
ext.myVariable = "Just an example!"
repositories(repoClosure)
}
repositories(repoClosure)
}
}
Then in your build.gradle apply it, like:
buildscript {
apply from: './my-repositories.gradle'
ext {
kotlin_version = '1.5.30'
}
dependencies {
classpath 'com.android.tools.build:gradle:7.0.4'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
// ...
