NoClassDefFoundError: javax/ws/rs/core/Configuration on application startup.

This is the sendbird-related parts of build.gradle

allprojects {
    repositories {
        mavenCentral()
        maven { url "https://repo.sendbird.com/public/maven" }
    }
}


dependencies {
    implementation 'org.sendbird:sendbird-platform-sdk:1.0.25'
}

And this is the configuration.

import org.sendbird.client.ApiClient;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class SendbirdConfig {

    @Value("${sendbird.api-token}")
    private String apiToken;

    @Value("${sendbird.application-id}")
    private String applicationId;

    @Bean
    public ApiClient apiClient() {
        try {
            ApiClient apiClient = org.sendbird.client.Configuration.getDefaultApiClient() // The error is thrown here.
                    .addDefaultHeader("Api-Token", apiToken);
            apiClient.setBasePath("https://api-" + applicationId + ".sendbird.com");
            return apiClient;
        } catch (Exception e) {
            e.printStackTrace();
            throw new RuntimeException(e);
        }
    }

}

And on the app start, it throws NoClassDefFoundError.

It seems like it needs javax/ws/rs/core/Configuration class, so I manually added the dependency into build.gradle

dependencies {
    implementation 'javax.ws.rs:javax.ws.rs-api:2.1.1'
}

And then, the error has changed to LinkageError.

I tried some other latest version of the rs-api dependency, but none of them works.
Should I add the dependency manually?

[flippingflop]

They say javax. namespace is not supported for SpringBoot 3, which is my project version sadly.
So I made a fatJar using shadowJar to relocate 'jakarta.ws.rs' namespace into 'javax.ws.rs'.

shadowJar {
    relocate 'jakarta.ws.rs', 'javax.ws.rs'
}

with dependency of

implementation 'jakarta.ws.rs:jakarta.ws.rs-api:2.1.6'

And now it says

Caused by: java.lang.NoClassDefFoundError: jakarta/ws/rs/core/EntityPart

which means some files have to remain in jakarta namespace.
I don't think that I can manually set all the class namespaces one by one, so just gonna call the rest apis manually.
Please comment for any help.

Hello, I'm experiencing the same issue. Did you manage to resolve it completely? I'm using Maven and am unsure if the “relocate” method you mentioned would work for me.
