# ERR\_PLUGIN\_DEV\_INVALID\_COMPONENT\_PARAMETER: Invalid parameter for plugin component creation[¶](https://doc.dataiku.com/dss/latest/troubleshooting/errors/ERR_PLUGIN_DEV_INVALID_COMPONENT_PARAMETER.html#err-plugin-dev-invalid-component-parameter-invalid-parameter-for-plugin-component-creation "Permalink to this headline")

The user is trying to add a non-working component to the plugin :

* adding a code env definition when there is already one

* adding a java component without specifying a fully qualified class name containing at least one package hierachy

## Remediation[¶](https://doc.dataiku.com/dss/latest/troubleshooting/errors/ERR_PLUGIN_DEV_INVALID_COMPONENT_PARAMETER.html#remediation "Permalink to this headline")

For duplicate code environment definitions, go to the editor tab and delete the old one. For incorrect class names, add a package to the fully qualified class name.
