Mule Maven Plugin Deployment Fails Due to Incorrect Environment Variable Argument

CAUSE

The Mule Maven Plugin expects a specific property name for passing the environment variable from the command line. Using `-Denvironment.env` is an incorrect syntax for this purpose. The plugin looks for a property named `env` (or similar, depending on your `pom.xml` configuration) directly. When the incorrect property name is used, the environment value is not passed to the plugin, resulting in it being treated as `null`.

SOLUTION

To correctly pass the environment variable to the Mule Maven Plugin during deployment, use the `-Denv` argument instead of `-Denvironment.env`.

1.  **Identify the incorrect command:**
    If your current deployment command includes `-Denvironment.env=<YOUR_ENVIRONMENT_NAME>`, this is likely the cause of the issue.

2.  **Modify the Maven command:**
    Replace `-Denvironment.env=<YOUR_ENVIRONMENT_NAME>` with `-Denv=<YOUR_ENVIRONMENT_NAME>`.

    **Incorrect Command Example:**
    ```bash
    mvn clean deploy -DmuleDeploy -Denvironment.env=DEV
    ```

    **Corrected Command Example:**
    ```bash
    mvn clean deploy -DmuleDeploy -Denv=DEV
    ```

    Ensure that `<YOUR_ENVIRONMENT_NAME>` matches the exact name of your environment as configured in Anypoint Platform (e.g., `DEV`, `UAT`, `PROD`).
