In my maven project there is the following dependency, which is successfully downloaded and works.
<dependency> <groupId>net.thucydides</groupId> <artifactId>thucydides-core</artifactId> <version>${thucydides.version}</version> </dependency> Now I add to the yandex html elements project, but I can’t do one thing - edit the SmartElementProxyCreator.java class in thucydides/thucydides-сore/src/main/java/net/thucydides/core/annotations/locators .
Idea always says that the file is read only , which is logical, since it is an external repository. 
How can I correctly change this class of external library and make deploy to my project?
