[Qbs] Conditionally adding a file tag

[Alberto Mardegan]

Hi all!
  I have a Product consisting of static files (images, QML and JSON);
you can see the base item here:


https://gitlab.com/mardy/mappero/-/blob/fd935d58a55523bf7d6b281f2728f055704a2b26/qbs/imports/QmlPlugin.qbs

and a trivial QBS file in which it's used:


https://gitlab.com/mardy/mappero/-/blob/fd935d58a55523bf7d6b281f2728f055704a2b26/src/plugins/nominatim/plugin.qbs

It all works fine, the static files are installed in the filesystem in
the proper location.


Now, however, I'm building the Android version and I would like to embed
the same file as a resource, but only when building for Android. So,
I've changed the base item like this:

=======
Product {
    type: embedAsResource ? "staticlibrary" : "qmlplugin"

    property bool embedAsResource: true   // logic is TODO

    Depends { name: "Qt.core" }
    ...
    FileTagger {

        patterns: [ "*.png", "*.gif", "*.svg" ]

        fileTags: "image"

    }

    FileTagger {
        patterns: "*.qml"
        fileTags: ["qml"]
    }

    Group {
        fileTagsFilter: [ "qml", "image" ]
        fileTags: embedAsResource ? ["qt.core.resource_data"] : []
        qbs.install: !embedAsResource
        qbs.installDir: "share/" + project.relativePluginDir
        qbs.installSourceBase: "../"
    }
=======

That is, if the embedAsResource property is true (and it always is,
currently), the product should be a static library, and the
"qt.core.resource_data" tag should be added to the static files.

But the above does not work. It appears that the new tag is not being
added. It all works if I add it directly into the FileTagger items, but
I would rather avoid doing that, since I have several of them and adding
a conditional would make the QBS file harder to read.

So, in short, the question is this: why isn't it possible to use the
Group's fileTags property to add a tag in this case? Or am I doing
something else wrong here?

Ciao,
  Alberto
