i am trying to use one of the method from the generated client as shown below

package io.swagger.client.api;

import com.squareup.okhttp.OkHttpClient;
import io.swagger.client.ApiClient;
import io.swagger.client.ApiException;
import io.swagger.client.Configuration;
import io.swagger.client.model.AppModel;
import io.swagger.client.model.NodeModel;
import java.util.List;
import java.util.logging.Level;
import java.util.logging.Logger;

public class testSample {
    private final PlatformApi api = new PlatformApi();
    public void getNodesTest() throws ApiException {
        List<AppModel> response = api.getApps();
        System.out.print("------------------------inside testsample------------------------");
        System.out.print(response);
    }

    public static void main(String args[]){
        testSample t1=new testSample();
        System.out.print("------------------------inside main------------------------");
        try{
            ApiClient defaultApiClient = Configuration.getDefaultApiClient();
            ApiClient apiClient = t1.api.getApiClient();
            System.out.println(defaultApiClient);
            System.out.println(apiClient);
            t1.getNodesTest();
        }
        catch(Exception e){
            System.out.println("inside exeption");
            e.printStackTrace();
        }



    }
}

Please provide some suggestion how to use the generated java client from swagger in local

The error below suggests that the Java API client couldn't connect to the API server:

io.swagger.client.ApiException: java.net.SocketTimeoutException: connect timed out

I would suggest you to verify the Swagger/OpenAPI spec to ensure it has a proper host setting, e.g. 

host: petstore.swagger.io

e.g. https://github.com/swagger-api/swagger-codegen/blob/master/modules/swagger-codegen/src/test/resources/2_0/petstore.yaml#L12

Ref: Swagger 2.0 spec: https://github.com/OAI/OpenAPI-Specification/blob/master/versions/2.0.md#swagger-object

I hope these helps someone;

DefaultApi defaultApi = new DefaultApi();
ApiClient apiClient = new ApiClient();
apiClient.setBasePath("http://....");
apiClient.addDefaultHeader("Authorization", "bearer TOKEN");
OkHttpClient httpClient = apiClient.getHttpClient();
httpClient.setConnectTimeout(60, TimeUnit.SECONDS);
httpClient.setReadTimeout(60, TimeUnit.SECONDS);
httpClient.setWriteTimeout(60, TimeUnit.SECONDS);
defaultApi.setApiClient(apiClient);

SomeModel var1 = defaultApi.getNodesTest();

generator sample command;

> java -jar swagger-codegen-cli-2.2.2.jar generate -l java -o myModule --library okhttp-gson -i http://..../swagger

to download jar file;

http://central.maven.org/maven2/io/swagger/swagger-codegen-cli/
