NoSuchMethod 'void org.hl7.fhir.validation.instance.InstanceValidator.<init> ?

[lasred]

Hi team,

This is how we're initiating our FhirInstanceValidator - following documentation - https://hapifhir.io/hapi-fhir/docs/v/6.10.5/validation/instance_validator.html

   FhirContext context = FhirContext.forR4();
  context.getCtx().newValidator();
   final FhirInstanceValidator instanceValidator = new FhirInstanceValidator(context.getCtx());
   validator.registerValidatorModule(instanceValidator);

However we get this error

NoSuchMethod 'void org.hl7.fhir.validation.instance.InstanceValidator.<init>(org.hl7.fhir.r5.context.IWorkerContext, org.hl7.fhir.r5.fhirpath.FHIRPathEngine$IEvaluationContext, org.hl7.fhir.r5.utils.XVerExtensionManager)' ?

when we try to call validator.validateWithResult

We're on 6.4.3

  <dependency>
        <groupId>ca.uhn.hapi.fhir</groupId>
        <artifactId>org.hl7.fhir.validation</artifactId>
        <version>6.4.3</version>
      </dependency>

Has anyone encountered this issue before?

this is some version mismatch between HAPI and HAPI-core, so you need to provide a lot more information about your maven set up

[lasred]

That makes sense. We are currently upgrading hapi to 7.4.5

    <dependency>
        <groupId>ca.uhn.hapi.fhir</groupId>
        <artifactId>hapi-fhir-base</artifactId>
        <version>7.4.5</version>
      </dependency>

Is 7.4.5 hapi compatible with hapi-core 6.4.3 ?

Let me know if there's any other information I can provide (I can include what versions our other dependencies are set at)

@lasred 7.4.5 uses version 6.3.23 of the core library.

It will not be compatible with version 6.4.3 of the core library.

The release of HAPI that is scheduled for November 22nd 2024 will contain an update to 6.4.0 of core.

If you need to specifically update 7.4.5, see this PR and branch, which you can build yourself: hapifhir/hapi-fhir#6459 There is no present plan to merge and release this branch, and it has not been QA tested.

[lasred]

That makes sense

If I'm understanding right, - the release of hapi core for tomorrow of 6.4.x (November 22nd) will be compatible with hapi 7.4.5?

[dotasek]

No, the release of HAPI (https://github.com/hapifhir/hapi-fhir) tomorrow will use version 6.4.0 of this library (https://github.com/hapifhir/org.hl7.fhir.core).
