QPluginLoader Plugin verification data mismatch

MartinD

I can succesfully load this plugin:

...
Q_PLUGIN_METADATA(IID "com.my.api")
...

I can't load this plugin:

...
Q_PLUGIN_METADATA(IID "com.my.api" FILE "api.json")
...

api.json contains:

{
    "name" :            "api",
    "version" :         "1.0"
}

This code then prints Plugin verification data mismatch error:

    QPluginLoader loader("api.dll");
    qDebug() << loader.errorString(); // Plugin verification data mismatch

Why and how to append my JSON data to the plugin?

May be silly , Did you put the following line in the main export class of the plugin:

Q_PLUGIN_METADATA(IID "com.my.api" FILE "api.json"

Possibly check :
Version of Qt version, the same (major and minor)version but a different Qt configuration?
Name mangling difference by compiler.
