Duplicate class error on scriptrunner

[Gaston]

 Hi,

I'm facing an intermittent issue with ScriptRunner (Jira Data Center) that seems related to class loading / caching.

Error

Invalid duplicate class definition of class EquipoJira.UtilidadesCampos :
The sources /home/jira/scripts/EquipoJira/UtilidadesCampos.groovy and
file:/home/jira/scripts/EquipoJira/UtilidadesCampos.groovy each contain
a class with the name EquipoJira.UtilidadesCampos.

File

/home/jira/scripts/EquipoJira/UtilidadesCampos.groovy

🧱 Class definition

package EquipoJira

public class UtilidadesCampos {
    public static Tuple2<String, String> GetRamoProducto(Issue issue) {}
}

📥 Usage

import EquipoJira.UtilidadesCampos

UtilidadesCampos.GetRamoProducto(issue)

 Context

• The class is defined in the ScriptRunner script root.
• It is used across multiple scripts via import.
• The error appears intermittently, not consistently
• There are no duplicate files with the same name in the filesystem.

What is the recommended way to define reusable utility classes in ScriptRunner without hitting this issue?
