Hello,

I am using SDM plugin in my java project and maven build is ok. I am using also sidecar in my application, but it is a nodejs application and doesn't find com.sap.cds/sdm, hence the build fails. Can you advise what I can do?

Regards,

🧪 Initial Analysis & Proposed Remediation

Summary & Root Cause Hypothesis
The issue describes a build failure in a Node.js sidecar application because it "doesn't find com.sap.cds/sdm," while a related Java project using the SDM plugin builds successfully. com.sap.cds/sdm is a Java Maven artifact representing the SAP Document Management (SDM) plugin.

My hypothesis is that the Node.js application, likely a CAP service or a UI application, is incorrectly attempting to reference or resolve this Java artifact directly within its own build context (e.g., in a .cds model file, package.json, or a Node.js source file). Node.js environments cannot directly resolve Java dependencies. Instead, the Node.js application should consume the SDM functionality as a service exposed by the Java CAP application (e.g., via OData or REST), rather than trying to import the underlying Java library. The build failure indicates a module resolution or path configuration error where com.sap.cds/sdm is treated as a local Node.js module or path.

🥇 Prioritized Remediation Steps (with Code Fixes)

1. Verify Annotation Placement (High Priority):

   • Rationale: In CAP Node.js projects, .cds files define the data model and services, often including using statements for external definitions or services. The error doesn't find com.sap.cds/sdm strongly suggests that a .cds file in the Node.js project is explicitly attempting to using { com.sap.cds.sdm } from 'com.sap.cds/sdm'; or a similar construct. This directly references a Java package name as if it were a Node.js module path, which will fail during the cds build process. This represents an incorrect "placement" of a Java-specific dependency within the Node.js model, directly impacting build-time model resolution and subsequent annotation processing.
   • Action & Required Change: Thoroughly examine all .cds model files within the Node.js sidecar application for any using statements, service definitions, or annotations that directly reference com.sap.cds/sdm. These direct references to Java artifacts must be removed. Instead, the Node.js application should be configured to consume the SDM functionality as an external service exposed by the Java application, typically through an OData or REST interface, and model that external service appropriately in its own .cds definitions (see step 3).

   --- a/srv/my-service.cds
   +++ b/srv/my-service.cds
   @@ -1,2 +1 @@
   -using { com.sap.cds.sdm } from 'com.sap.cds/sdm'; // Remove this line which incorrectly references a Java artifact.
   // Replace this with a proper external service definition or connection via package.json.

2. Inspect OData $metadata Output (High Priority):

   • Rationale: While the immediate issue is a Node.js build failure, it's crucial to confirm that the Java CAP application correctly exposes its SDM-related services via standard OData metadata. If the Java backend's $metadata contains malformed references or inadvertently leaks internal Java package names (com.sap.cds/sdm) in a way that the Node.js cds build process might try to interpret when generating client proxies or inferring models, it could contribute to the Node.js build error. This step verifies the backend's contract is clean and consumable.
   • Action & Command: Deploy the Java CAP application (if not already deployed) and access its OData service's $metadata document. Confirm that the service definitions and entity types related to SDM are correctly exposed using standard OData constructs (e.g., EntitySets, EntityTypes, NavigationProperties) and do not contain any com.sap.cds/sdm as a direct identifier in property names, types, or namespaces that would be misinterpreted by a Node.js parser.

   GET https://<your-java-cap-service-url>/odata/v4/sdm/$metadata
   

   Expected State: The $metadata output should be valid OData XML/JSON, describing the service entities and actions without any direct references to Java package names like com.sap.cds/sdm.

3. Test UI-Level Override (Medium Priority):

   • Rationale: If the Node.js sidecar is a CAP service or an application that consumes external services, its package.json (cds.requires section) or manifest.json (for UI5 apps) defines how these services are connected. If the build issue persists after checking .cds files, the Node.js project's package.json might be misconfigured in its cds.requires to consume the SDM service. This step ensures that the Node.js sidecar is correctly declared to consume the external Java-based SDM service, preventing it from trying to resolve com.sap.cds/sdm as a local dependency or misinterpreting its source.
   • Action & Required Change: Modify the Node.js sidecar's package.json to explicitly declare its dependency on the SDM service exposed by the Java application. This configuration informs the CAP framework about the external service, allowing it to correctly generate proxies or connect at runtime, and prevents the Node.js build from attempting to resolve Java artifacts.

   {
     "name": "my-nodejs-sidecar",
     "dependencies": {
       "@sap/cds": "^7"
       // ... other Node.js dependencies
     },
     "cds": {
       "requires": {
         "SDMService": { // Logical name for the SDM service in Node.js project
           "kind": "odata",
           "model": "srv/external/sdm", // Path to the Node.js project's local CDS definitions of the external SDM service
           "credentials": {
             "destination": "my-sdm-destination", // Use a destination for productive landscapes
             "url": "https://<your-java-cap-service-url>/odata/v4/sdm" // Example direct URL for local testing/deployment
           }
         }
       }
     }
   }

Risk Assessment
Applying the proposed fixes involves correcting configuration and model definitions within the Node.js sidecar application. The risk is considered Low. The changes are primarily declarative (removing incorrect references and adding proper service consumption configurations) and align with standard CAP development practices for inter-service communication. Incorrect application of these changes could lead to new build errors or runtime issues if the external SDM service is not correctly modeled or connected. Thorough testing of the Node.js application's build process and its runtime integration with the Java SDM service would be required after applying these remediations.
