What do you expect here? The full properties map?
Or is it a subset of properties (I'll assume that). In that case, you'll
want to inject @Named("<property_name>") into your plugin for every plugin
you want to return.
As an alternative, you can bind the Properties as a first class object,
inject the properties into each property, and then extract the ones you
care about:
bind(Properties.class)
.annoatedWith(ContainsPluginProperties.class)
.toInstance(properties);
...
@Inject SjcPluginProperty(@ContainsPluginProperties Properties properties) {
this.properties = properties;
}
