mvn install

To deploy it to a remote Maven repository instead, configure the settings of the repository and execute:

mvn deploy

Refer to the official documentation for more information.

Maven users

Add this dependency to your project's POM:

<dependency>
    <groupId>io.github</groupId>
    <artifactId>nifi-api-client-java</artifactId>
    <version>1.0.0</version>
    <scope>compile</scope>
</dependency>

Gradle users

Add this dependency to your project's build file:

compile "io.github:nifi-api-client-java:1.0.0"

Others

At first generate the JAR by executing:

mvn package

Then manually install the following JARs:

  • target/nifi-api-client-java-1.0.0.jar
  • target/lib/*.jar

Getting Started

Please follow the installation instruction and execute the following Java code:

import io.swagger.client.auth.*;
import io.swagger.client.model.*;
import io.swagger.client.api.AccessApi;

import java.io.File;
import java.util.*;

public class AccessApiExample {

    public static void main(String[] args) {
        
        AccessApi apiInstance = new AccessApi();
        String username = "username_example"; // String | 
        String password = "password_example"; // String | 
        try {
            String result = apiInstance.createAccessToken(username, password);
            System.out.println(result);
        } catch (ApiException e) {
            System.err.println("Exception when calling AccessApi#createAccessToken");
            e.printStackTrace();
