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?

Hi @Gaston 

try this, if it helps 

check below
- Go to ScriptRunner → Settings → Script Roots.
- Ensure only one root path is defined (e.g., /home/jira/scripts).
- Remove duplicates or overlapping paths that point to the same directory.

try
clearing ScriptRunner caches

trying using Consistent Imports
import EquipoJira.UtilidadesCampos

Thanks. I verified a few things on my side:

There is only a single script path configured: /home/jira/scripts
UtilidadesCampos.groovy contains only one class definition:
package EquipoJira
class UtilidadesCampos { ... }

I am importing it consistently as:
import EquipoJira.UtilidadesCampos

I also confirmed that this file is not being loaded via GroovyShell, evaluate, parseClass, or similar mechanisms

Even with that, the error still appears intermittently:

Invalid duplicate class definition of class EquipoJira.UtilidadesCampos
with the same file being referenced both as a filesystem path and as a file: URL.

Also, clearing ScriptRunner caches several times sometimes makes the issue disappear temporarily, which makes this look more like a classloader/cache invalidation problem than a duplicated file or import issue.

Is this a known issue in ScriptRunner for Jira Data Center?
Are there recommended patterns for reusable helper classes under the script root to avoid this kind of intermittent duplicate class definition error?
