Warning

⚠️ Blocking Issue

Remove the '-SNAPSHOT' suffix and use a purely numeric version (e.g., 3.0.3 or 3.0.2). If you need to mark a development version, consider using the 'In Development' flag or managing the snapshot status via the Gradle build configuration instead of the database metadata.

<!--36D2DDA4D6CE411C8A6096D0C13C7A7F-->  <VERSION><![CDATA[3.0.3]]></VERSION>

Rationale: The Etendo framework's version parsing logic (e.g., OpenbravoVersion class) splits the version string by dots and attempts to convert each part to an integer using Integer.valueOf() or Integer.parseInt(). Including a non-numeric suffix like '-SNAPSHOT' will trigger a NumberFormatException, leading to runtime failures in module management and dependency resolution.
