I am new to Salesforce technology and I have practiced basic lightning course in Salesforce developer console. I am trying to implement same in Eclipse IDE with force.com plugin. I have imported all projects from my salesforce account into eclipse IDE by providing all the salesforce credentials, but when I tried to preview my app by clicking Force.com --> Show in Salesforce Web it is taking me to the web page which is URL No Longer Exists. I am able to see my web page when I click preview in Developer Console but in Eclipse I'm unable to do.
NOTE: The URL when I run from developer console is different from the URL when I click Show in Salesforce Web from ECLIPSE.
What are the settings I need to update or how to change URL so that when I click run button in Eclipse I can view my lightning web page in the browser?
