myconfigs | linux bash zsh shell vim and so on I will write

The problem is caused by the missing TypeConverter that knows how to create an instance of MyConfig.Instance from another type. The property source resolver sees a.b.instances configuration as a List, so for every entry it tries to find a converter that satisfies Map -> MyConfig.Instance. Because there is no one that explicitly satisfies such conversion, it falls back to Map -> Object type converter. This converter uses Jackson's serialization and deserialization, and it also does not work because Jackson does not know how to deserialize a JSON like this:

Solution Example:

It reads globalconfigs.json, loops through each application, checks if NewConfigsBool is true or false.

If NewConfigsBool is true, it loops through all application .files and adds or upodates %file%.globalsettings.values.%parameterName%.

The part for SQL is not implemented so it's similar and it's for you 😉

You should do all before exporting. Something like this:

//Here I had in first answer code with generating xml document, but you need just to export it to csv. My bad.

You can do this:

This code is if you want to have more control over it and add some other things like checking values and etc...
