# Java SDKs

Use the IONOS Cloud Java SDKs to build Java apps on IONOS Cloud. Each SDK is available on Maven Central.

### Quick Start

Add the SDK to your Maven project:

```xml
<dependency>
    <groupId>com.ionoscloud</groupId>
    <artifactId>ionos-cloud-sdk</artifactId>
    <version>LATEST</version>
</dependency>
```

Or with Gradle:

```groovy
implementation 'com.ionoscloud:ionos-cloud-sdk:LATEST'
```

Set up a client:

```java
import com.ionoscloud.ApiClient;
import com.ionoscloud.Configuration;

ApiClient client = Configuration.getDefaultApiClient();
client.setUsername(System.getenv("IONOS_USERNAME"));
client.setPassword(System.getenv("IONOS_PASSWORD"));
```

Use a token instead:

```java
HttpBearerAuth tokenAuth =
    (HttpBearerAuth) client.getAuthentication("Token Authentication");
tokenAuth.setBearerToken(System.getenv("IONOS_TOKEN"));
```

### Authentication

All Java SDKs use the same credentials. Store them in environment variables and keep them out of your source code.

```bash
export IONOS_USERNAME=your@email.com
export IONOS_PASSWORD=yourpassword

# Use a token for CI/CD:
export IONOS_TOKEN=your_api_token
```

### GitHub Repositories

All Java SDKs are open source on GitHub under [ionos-cloud](https://github.com/ionos-cloud). Product SDKs follow the pattern `ionos-cloud-sdk-{service}`.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ionos.com/cloud/java/java-sdks.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
