+### Global gradle properties
+
+To authenticate with Gradle to access repositories that require authentication, you can set your user and token in the `gradle.properties` file.
+
+Here's how you can do it:
+
+1. Open or create the `gradle.properties` file in your Gradle user home directory:
+  - On Unix-like systems (Linux, macOS), this directory is typically `~/.gradle/`.
+  - On Windows, this directory is typically `C:\Users\<YourUsername>\.gradle\`.
+2. Add the following lines to the `gradle.properties` file:
+    ```properties
+    repository.user=your_user
+    repository.token=your_token_value
+    ```
+   or use environment variables `REPOSITORY_USER` and `REPOSITORY_TOKEN`
