HERE Gradle Resolver for Workspace and Marketplace

Introduction

The HERE platform Gradle resolver plugin provides Java and Scala developers with access to HERE platform artifacts via Gradle. It uses your HERE platform credentials to generate tokens so that it can pull your Gradle project dependencies from the HERE platform.

This allows Marketplace and Workspace users to fetch platform schemas. In addition, the users can fetch the Java / Scala Data Client Library which offer access to data in the HERE Data API.

Go to the HERE Developer portal to learn more about the HERE platform.

Limitation

The Gradle resolver plugin is provided 'as is' and not officially part of Workspace or Marketplace. While there is no official support by HERE, you may still raise issues via GitHub. We may be able to help.

Prerequisites

To access the libraries and schemas from the HERE platform, you need a HERE Workspace and/or a HERE Marketplace account. If you don’t have an account yet, go to Pricing and Plans to apply for a free trial.

Once you have enabled your account you need to create the credentials and prepare your environment. Workspace users can find corresponding guidance in the documentation for Java and Scala developers. Marketplace users can find instructions in the Marketplace Consumer user guide.

Please note, by default the Gradle resolver plugin uses the credentials.properties file provided in the .here directory in the user home directory. There are three options to override the credentials:

• The first option is the system property hereCredentialsFile, the property should be added to the maven command the following way -DhereCredentialsFile=/full/path/to/credentials.properties.
• The second option is the environment variable HERE_CREDENTIALS_FILE. The variable should contain the full file path to the credentials.properties file to be used. The variable is taken into account only if there is no system property provided.
• The third option is the environment variable HERE_CREDENTIALS_STRING, the variable should have the following format:

here.access.key.id=...
here.access.key.secret=...
here.client.id=...
here.user.id=...
here.token.endpoint.url=...

Note that providing credentials via HERE_CREDENTIALS_STRING variable have the lowest precedence

How to use it?

This Gradle resolver plugin is published on Maven Central so you can conveniently use it from your project. The gradle-resolver plugin can be registered by adding an entry to build.gradle file as follows:

plugins {
    id 'com.here.platform.artifact.gradle' version '1.0.0'
}
repositories {
    here()
}

For example, to fetch the HERE Map Content - Topology Geometry - Protocol Buffers schema and the related Java and Scala bindings set the following dependencies:

dependencies {
    implementation "com.here.schema.rib:topology-geometry_v2_java:2.109.0"
}

Proxy Setup

To enable Gradle and the HERE Gradle resolver plugin to work behind a proxy, you need to use standard http_proxy and https_proxy environment variables, like:

gradle build -Dhttps.proxyHost=$PROXY_HOST  -Dhttps.proxyPort=$PROXY_PORT -Dhttps.proxyUser=$PROXY_USERNAME -Dhttps.proxyPassword=$PROXY_PASSWORD

Alternatively, pass those by setting JAVA_OPTS in the environment variable, like:

export JAVA_OPTS="-Dhttps.proxyHost=$PROXY_HOST  -Dhttps.proxyPort=$PROXY_PORT -Dhttps.proxyUser=$PROXY_USERNAME -Dhttps.proxyPassword=$PROXY_PASSWORD"
