Maven repository

All components are getting published on maven.mozilla.org. To use them, you need to add the following to your projects top-level build file, in the allprojects block (see e.g. the reference-browser):

repositories {
    maven {
       url "https://maven.mozilla.org/maven2"
    }
}

Snapshot builds

Snapshots are build daily from the master branch and published on snapshots.maven.mozilla.org.
