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

[flippingflop]

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.
