androiddeployqt does not strip quotation marks from static namespace string retrieved from build.gradle

When providing and using a custom build.gradle and setting a static namespace string, androiddeployqt will retrieve the namespace string including the surrounding quotation marks. This leads to androiddeployqt complaining about a package name including illegal characters and modifying it.

Note that this only happens with a static string. Using the default "androidPackageName" variable does not exhibit this issue.

A demo project is attached, as well as screenshots of modifications I made to androiddeployqt to diagnose this and the results.
