What is the procedure if the "sourceLocale" is not English?

[ChristophM2000]

If my "sourceLocale" is "en", then everything fits together. Kendo's "sourceLocale" is "en" and if I want to translate my application into German, for example, I create a "messages.de.xlf" file with "ng extract-i18n" into which I then merge the Kendo translations with "npx kendo-translate messages.de.xlf --locale de".

But what if my source locale is "de"? Then there is no file "messages.de.xlf" for the language German into which "kendo-translate" could put its translations.
The end result is that I have an application in which on the one hand my own texts are in German and the texts from Kendo are in English.

How can this scenario be solved?

I'm facing the same problem with "sourceLocale" set to "it".
Is there any solution to this?

It is not possible to use a non-English sourceLocale.

To solve the problem, the sourceLocale must be included in locales. To prevent a “/locale” route from being created, simply set baseHref = “”.

Before:

"i18n": {
    "sourceLocale": {
      "code": "de",
    },
    "locales": {
      "en-DE": {
        "translation": "apps/overview-app/src/locale/messages.en-DE.xlf",
        "baseHref": "en"
      }
    }
  },

After:

  "i18n": {
    "locales": {
      "de": {
        "translation": "apps/overview-app/src/locale/messages.xlf",
        "baseHref": ""
      },
      "en-DE": {
        "translation": "apps/overview-app/src/locale/messages.en-DE.xlf",
        "baseHref": "en"
      }
    }
  },
