Features

• Efficient, type-safe access to the AdoptOpenJDK API
• Clean API/implementation separation for easy API mocking in applications
• JPMS-ready
• OSGi-ready
• High coverage automated test suite
• Apache 2.0 license
• Fully documented (JavaDOC)

Usage

Use the following Maven dependencies:

<dependency>
  <groupId>net.adoptopenjdk</groupId>
  <artifactId>net.adoptopenjdk.v3.api</artifactId>
  <version><!-- Insert latest version --></version>
</dependency>
<dependency>
  <groupId>net.adoptopenjdk</groupId>
  <artifactId>net.adoptopenjdk.v3.vanilla</artifactId>
  <version><!-- Insert latest version --></version>
</dependency>

The first dependency specifies that you want to use the API, and the second is a basic provider for the API.

Then:

var clients = new AOV3Clients();
try (var client = clients.createClient()) {
  var request = client.availableReleases(...);
  var releases = request.execute();
}

The API operates entirely synchronously and raises checked exceptions on failures.

The net.adoptopenjdk.v3.api.AOV3ClientProviderType interface is published both as a JPMS service and an OSGi service in order to allow for decoupling consumers from the vanilla implementation package:

var clients =
  ServiceLoader.load(AOV3ClientProviderType.class)
    .findFirst()
    .orElseThrow(() -> new IllegalStateException(
      String.format("No implementations of %s are available", AOV3ClientProviderType.class)));

try (var client = clients.createClient()) {
  var request = client.availableReleases(...);
  var releases = request.execute();
}
