New Versions of SAP Cloud SDK: 3.20.0 for Java, 1.20.1 for JavaScript, v33 for Continuous Delivery

[former_member646845]

We have released new versions of the SAP Cloud SDK. In detail, the following components are now available in new versions:

• Java libraries in version 3.20.0


• JavaScript libraries in version 1.20.1


• Continuous delivery toolkit in version v33

In this blog post, we will walk you through the highlights of these releases. For a complete overview, visit our release notes for the Java libraries, for the JavaScript libraries, and for the continuous delivery toolkit. The release notes also include the change log of all our releases so far.
At the end of the article, you will find a set of instructions on how to update to the new versions.

Java Libraries: Release Highlights 3.20.0

You can update your dependencies of the SAP Cloud SDK for Java to version 3.20.0 and get the new version from Maven Central.

In this release, we added a new builder pattern for type Resilience4jDecorationStrategy enabling custom function decoration properties.

Also, the experimental interface ServiceWithNavigableEntities was introduced for recursive traversal of navigation properties in entity sets that are part of an OData v4 virtual data model (VDM). This generic type offers type-safe methods to create a request along with chained entities with their navigation properties. By delegating to the existing request builder classes, the interface supports all basic CRUD operations (create, read, update, delete), plus count. All existing request modifiers are supported (e.g. filter or select statements in Read). The methods and sub-types in this interface are still open for changes in the future.


As an example, here is how to create a new Trip in Vacation (id 2020) of a person (username "John").


Let's assume that our API expects this HTTP request:
POST /ODataService/People('John')/Vacations(2020)/Trips


In our cloud application using SAP Cloud SDK, we would write this code:

Trip tripItem = createTrip();



  CreateRequestBuilder createRequest = service

    .forEntity( Person.builder().username("John").build() )

    .navigateTo( Person.VACATIONS )

    .forEntity( Vacation.builder().id(2020).build() )

    .navigateTo( Vacation.TRIPS )

    .create( tripItem );

  

  createRequest.execute( destination );

Further improvements

Several further improvements are listed in the full release notes.

JavaScript Libraries: Release Highlights 1.20.1

The JavaScript libraries of the SAP Cloud SDK are now available in version 1.20.1.

An issue with the OData client generator was fixed, which prevented parsing of definitions in OpenAPI format with versions higher than 3.

Further improvements

As usual, the full release notes contain a list of all improvements in this release.

Continuous Delivery Toolkit: Release Highlights v33

We have also released version v33 of our out-of-the-box continuous delivery offering consisting of a ready-made Jenkins server and a complete delivery toolkit.

Shared Configuration

The shared configuration property in the pipeline configuration file .pipeline/config.yml has changed. From this release on, it must be a list of strings named customDefaults, located on the top level. This change is necessary to align the SAP Cloud SDK Pipeline closer with Project Piper.

Maven 3.6 or higher is required

Please note that maven-related functionality requires Maven version 3.6 or higher in the configured Docker image.

Further improvements

SonarQube scans can run in all branches of a project. This can be enabled by setting the runInAllBranches property in the pipeline configuration.

You can find further fixes and improvements in the complete release notes.

How to Update

Java libraries

To update the version of the SAP Cloud SDK Java libraries used in an existing project, proceed as follows:

• Open the pom.xml file in the root folder of your project.


• Locate the dependency management section and therein the sdk-bom dependency.


• Update the version of that dependency to 3.20.0.

With this, you are already done thanks to the "bill of material" (BOM) approach. Your dependency should look like this:

<dependencyManagement>

    <dependencies>

        <dependency>

            <groupId>com.sap.cloud.sdk</groupId>

            <artifactId>sdk-bom</artifactId>

            <version>3.20.0</version>

            <type>pom</type>

            <scope>import</scope>

        </dependency>

    </dependencies>

    <!-- possibly further managed dependencies ... -->

</dependencyManagement>

If you update from a version prior to 3.0.0, have a look at our migration guide.

If you are using the SAP Cloud SDK in a project of the SAP Cloud Application Programming Model, replace sdk-bom with sdk-modules-bom to only update the version of SDK modules, not further dependencies.
You can now recompile your project (be aware of the compatibility notes, though) and leverage the new features of the SAP Cloud SDK in version 3.20.0.

Of course, you can also generate a new project that uses version 3.20.0 from the start by running the Maven archetypes for Neo or Cloud Foundry with -DarchetypeVersion=3.20.0 (or RELEASE).

JavaScript libraries

To update the version of the SAP Cloud SDK JavaScript libraries used in an existing project, use the command npm update in the root folder of your module. Note that this will also update other modules, unless you explicitly specify which packages to update. If you want to check beforehand what will change, use npm outdated.

Continuous Delivery Toolkit

If you are using the pipeline with a fixed version (as recommended since v7), update the continuous delivery toolkit with the following command, that you run on the server hosting the cx-server:

./cx-server update image
