Step 1. Add the JitPack repository to your build file

Add it in your root settings.gradle at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

Add it in your settings.gradle.kts at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url = uri("https://jitpack.io") }
		}
	}

Add to pom.xml

	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>

Add it in your build.sbt at the end of resolvers:

 
    resolvers += "jitpack" at "https://jitpack.io"

Add it in your project.clj at the end of repositories:

 
    :repositories [["jitpack" "https://jitpack.io"]]

Step 2. Add the dependency

	dependencies {
		implementation 'com.github.Vineeth-Mohan:OfflineReverseGeocode:1.0'
	}
	dependencies {
		implementation("com.github.Vineeth-Mohan:OfflineReverseGeocode:1.0")
	}
	<dependency>
	    <groupId>com.github.Vineeth-Mohan</groupId>
	    <artifactId>OfflineReverseGeocode</artifactId>
	    <version>1.0</version>
	</dependency>

                            
    libraryDependencies += "com.github.Vineeth-Mohan" % "OfflineReverseGeocode" % "1.0"
        
        

                            
    :dependencies [[com.github.Vineeth-Mohan/OfflineReverseGeocode "1.0"]]

Readme

An Offline Reverse Geocoding Java library

Uses KD-Trees for extremely fast placename lookups

Licensed under The MIT License

A C# port by Necrolis is available at https://github.com/Necrolis/GeoSharp

Usage:

First download a placenames file from http://download.geonames.org/export/dump/

Allcountries.zip from that site is comprehensive however if you're on mobile try the cities1000.zip file. It's 1/80th of the size.

Then simply

ReverseGeoCode reverseGeoCode = new ReverseGeoCode(new FileInputStream("c:\\AU.txt"), true);

System.out.println("Nearest to -23.456, 123.456 is " + geocode.nearestPlace(-23.456, 123.456));
