Maven has a way to configure mirrors in settings.xml. Gradle doesn’t have a direct analogue to it, but what it has is really nice. Also it’s under-documented.
Let’s say you’re using gradle at work, and you want to use your company’s maven mirror. You might want to do this for numerous reasons.
The connection to the open internet is very slow
The connection to the open internet protected by a proxy that prevents access to maven central
You want to audit what is being used in projects at work
Let’s say your maven mirror’s url is http://repo.internal.example.com/releases
Just create a file called init.gradle under $USER_HOME/.gradle with this in it
allprojects { (1)
buildscript { (2)
repositories {
mavenLocal() (3)
maven { url "http://repo.internal.example.com/releases" } (4)
}
}
repositories { (5)
mavenLocal()
maven { url "http://repo.internal.example.com/releases" }
}
}| 1 | This says we want to apply to all projects on this machine. |
| 2 | This says you want to modify the build script dependencies too. This will make gradle plugins and build dependencies also use your mirror. |
| 3 | This says to look in maven local first. That’s typically your $USER_HOME/.m2/repository directory. |
| 4 | This says to look at your maven mirror next if the artifact could not be found. |
| 5 | This says to do the same set of changes for non-build dependencies of your gradle projects. |
