# Java

## 📁 **Preparing Your Project Files**

Before deploying, **your project must be** [**compiled into an executable JAR file**](/en/faq/general-questions/how-to-build-and-package-a-java-application.md). When compressing your project, ensure that **the `.jar` file is placed at the** [**root**](/en/faq/general-questions/what-is-the-root-of-the-project.md) **of the** [**`.zip`**](/en/faq/general-questions/wip-how-to-compress.md) **archive.**

#### ❌ **Files to Exclude**

Ensure the following files and directories are **not** included in your [`.zip`](/en/faq/general-questions/wip-how-to-compress.md):

```diff
- package-lock.json
- node_modules/
- .cache/
- .git/
```

📌 **Use a** [**`.discloudignore`**](/en/configurations/.discloudignore.md) **file** to automatically exclude these files.

## 📦 **Compiling Your Java Application**

To **deploy your Java application**, it must be compiled into an **executable JAR file**.

{% tabs %}
{% tab title="Maven" %}
📄 **Maven Official Documentation** → <https://maven.apache.org/guides/index.html>

```bash
mvn clean package
```

{% endtab %}

{% tab title="Gradle" %}
📄 **Gradle Official Documentation** → <https://docs.gradle.org/current/userguide/userguide.html>

```bash
gradle clean build
```

{% endtab %}
{% endtabs %}

{% hint style="info" %}

#### **Recommendation**

Rename your JAR file to a simple name like `app.jar` to avoid issues with special characters.​
{% endhint %}

***

## 📝 **Setting the Main File**

The `MAIN` parameter in your [`discloud.config`](https://github.com/discloud/docs/blob/english/configurations/discloud.config) file should point to your executable JAR file. For example:

```ini
MAIN=app.jar
```

Ensure that `app.jar` matches the name of your compiled JAR file.​

**Note:** For detailed information on setting the main file, refer to Discloud's FAQ on the main file.

## ✍️ **Deploying Your Applicaton**
