Description of problem

XML validation fails when creating a Maven Settings credential when the input file is using the http://maven.apache.org/SETTINGS/1.0.0 schema. This doesn't happen when using a file with the http://maven.apache.org/SETTINGS/1.2.0 schema.

How reproducible

Always

Steps to Reproduce:

• Create a new Maven Settings credential.
• Upload the attached tackle-test.xml file

Actual results

An error is displayed in the UI (see attached screenshot):

file_0.xml:2: element settings: Schemas validity error : Element '{http://maven.apache.org/SETTINGS/1.0.0}settings': No matching global declaration available for the validation root.

Expected results

The file is validated and can be used.

Additional info

Changing the file settings for the following will make it work:

<settings xmlns="http://maven.apache.org/SETTINGS/1.2.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.2.0 https://maven.apache.org/xsd/settings-1.2.0.xsd">
