google-cloud-translate java.lang.ClassNotFoundException: com.google.cloud.translate.v3beta1.BatchTranslateDocumentResponse

[energy2522]

Hi, I'm trying to use google-cloud-translate library version 2.29.0. I build a client using this code:

final var settings = TranslationServiceSettings.newBuilder()
                .setCredentialsProvider(credentialsProvider).build();

        return TranslationServiceClient.create(settings);

but I got an error saying:

The java version is 17, building tool is Gradle.

I tried to add a dependency with this class: 'com.google.api.grpc:proto-google-cloud-translate-v3beta1:0.111.0', but then I got this error:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

Action:

Correct the classpath of your application so that it contains compatible versions of the classes com.google.cloud.translate.v3beta1.stub.TranslationServiceStubSettings and com.google.api.gax.core.GoogleCredentialsProvider$Builder

How did you declare the dependency? Did you follow one of the ways from the README?

[energy2522]

@blakeli0 I'm using gradle without BOM, so I declare it as dependencies in this way:

	implementation 'com.google.cloud:google-cloud-translate:2.29.0'
	implementation 'com.google.api.grpc:proto-google-cloud-translate-v3beta1:0.111.0'

@energy2522 were you able to resolve this? https://cloud.google.com/java/docs/reference/google-cloud-translate/latest/overview#gradle contains Gradle-specific installation instructions that may be useful.

I assume this is resolved with no further response in last couple of month. Feel free to reopen if this is still an issue for you.
