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.wsw0108:java-vector-tile:1.3.4'
	}

	dependencies {
		implementation("com.github.wsw0108:java-vector-tile:1.3.4")
	}

	<dependency>
	    <groupId>com.github.wsw0108</groupId>
	    <artifactId>java-vector-tile</artifactId>
	    <version>1.3.4</version>
	</dependency>


                            
    libraryDependencies += "com.github.wsw0108" % "java-vector-tile" % "1.3.4"


                            
    :dependencies [[com.github.wsw0108/java-vector-tile "1.3.4"]]

Java Vector Tiles

A java encoder and decoder for vector tiles according to Mapbox vector tile spec

Encode a vector tile

VectorTileEncoder encoder = new VectorTileEncoder();

// Add one or more features with a layer name, a Map with attributes and a JTS Geometry. 
// The Geometry uses (0,0) in upper left and (256,256) in lower right.
encoder.addFeature("road", attributes, geometry);

// Finally, get the byte array
byte[] encoded = encoder.encode();

or, specifying the feature id:

VectorTileEncoder encoder = new VectorTileEncoder();
encoder.addFeature("road", attributes, geometry, id);
byte[] encoded = encoder.encode();
