Add a init.gradle to your user gradle folder. The init.gradle is recognized on every project.

Unix: ~/.gradle/init.gradle

These are also alternative locations where init script can be placed and loaded automatically:-

• Any *.gradle file in USER_HOME/.gradle/init.d
• Any *.gradle file in the Gradle installation’s init.d directory

init.gradle with mavenLocal as repository in all projects.

allprojects {
    repositories {
        mavenLocal()
    }
}

With that you have your local maven cache available in all repositories. A use case could be to use a jar that you put in ther with "gradle install" in another project without adding the mavenLocal repository to the build.gradle or adding a nexus/artifactory server.
