commercetools JVM SDK

**This commercetools JVM SDK is in its Maintenance Support mode currently, and is planned to be deprecated, please note the following dates.

We recommend to use our Java SDK V2, and you can migrate to the new version using our migration guideline.

The JVM SDK enables developers to use Java 8 methods and objects to communicate with the Composable Commerce API rather than using plain HTTP calls.
Users gain type-safety, encapsulation, IDE auto completion and an internal domain specific language to discover and formulate valid requests.

JDK compatibility

Tested with JDKs: Oracle 1.8.0_221, OpenJDK 1.8.0_221 and Amazon Corretto 8.222.10.1.

Using the SDK

• install Java 8
• (since May 19, 2016 new link) Javadoc, there you find also code snippets and insights
  • Getting Started
  • Release Notes

Modules

• commercetools-java-client: alias for commercetools-java-client-ahc-2_0
• commercetools-java-client-apache-async: uses Apache HTTP client
• commercetools-java-client-ahc-1_9: uses async HTTP client 1.9 (AHC 1.9 is incompatible to AHC 1.8)
• commercetools-java-client-ahc-2_0: uses async HTTP client 2.0 (do not mix it with the other AHC modules)
• commercetools-java-client-ahc-2_5: uses async HTTP client 2.5 (AHC 2.5 is incompatible to AHC 2.0)
• commercetools-java-client-ahc-2_12: uses async HTTP client 2.12
• commercetools-models: models which do not depend to a client implementation

Java SDK with gradle

repositories {
    mavenCentral()
}

    def jvmSdkVersion = "1.61.0"
    compile "com.commercetools.sdk.jvm.core:commercetools-models:$jvmSdkVersion"
    compile "com.commercetools.sdk.jvm.core:commercetools-java-client:$jvmSdkVersion"

JVM SDK Contrib

Useful code from external developers

• https://github.com/commercetools/commercetools-jvm-sdk-contrib
• contains also ProductImageUploadCommand from https://docs.commercetools.com/http-api-projects-products.html#upload-a-product-image

Short-term roadmap

• https://waffle.io/commercetools/commercetools-jvm-sdk

Open Source Examples

• Sunrise Java - a shop using Play Framework 2.x with Handlebars.java as template engine, Google Guice for DI
• Donut - single product subscription shop example with Play Framework 2.x and Twirl (Plays default) as template engine
• commercetools Spring MVC archetype - template integrating the SDK with Spring DI and Spring MVC and showing just some products, thymeleaf template engine
• Reproducer Example - a demo which shows how to reproduce errors

Stability

1. Experimental features in the API are also experimental features of the SDK.
   • this includes for example
     • payments
     • nested product attributes
2. The dependencies will only be updated in the next major version to improve stability. Of course, if bugs in libraries occur, we may need to update.
3. JVM SDK test dependencies and build tools can be updated because they don’t affect the production code.
4. The JVM SDK has an abstract HTTP client layer so old or new http client versions can be used.
5. order import is experimental
6. the search methods with lambda parameters are beta ProductProjectionSearch.ofCurrent().withQueryFilters(m -> m.categories().id().containsAll(categoryIds1))
7. getters of draft objects might change since new HTTP API features can introduce polymorphism
8. final classes without public constructors can be transformed into an interface

Executing integration tests

1. create a NEW API client in the Admin Center (https://mc.commercetools.com/YOUR_PROJECT_KEY/settings/developer/api-clients) with all available permissions (at the time of writing it is manage_payments manage_my_profile manage_orders view_products view_customers view_payments view_types manage_my_orders manage_types manage_customers manage_products view_orders manage_project), the by default created client has just manage_project
2. in the Admin Center in the “DANGER ZONE” activate the checkbox “ENABLE MESSAGES” within the “Messages Settings”
3. set “de”, “de-AT”, “en” as languages in the Admin Center
4. set at least one country in the Admin Center
5. create a file “integrationtest.properties” inside the project root
6. fill it with the credentials of a new empty Project which is for testing;

projectKey=YOUR project key without quotes
clientId=YOUR client id without quotes
clientSecret=YOUR client secret without quotes
apiUrl=https://api.europe-west1.gcp.commercetools.com
authUrl=https://auth.europe-west1.gcp.commercetools.com

1. use ./mvnw verify to execute all integration tests
2. use ./mvnw -Dit.test=*Product* -DfailIfNoTests=false verify to execute all integration test classes which have “Product” in the class name
3. for running the unit tests use ./mvnw test
4. alternatively use your IDE to execute the tests
5. for some IDEs like IntelliJ IDEA you need to add the Javac flag “-parameters”, then also rebuild the whole project to apply the change
