I have tried to install Force.com IDE in Eclipse and also download the feature to be able to work with Lightning Components in Eclipse. However I was not able to make it work.
I have also asked for it on Developer Forums, so please, take a look at this link where I explain better the use case.
I have also see this post here, but I would like not to use ATOM.
Really appreciate if someone could help me with this.
Force.com > Project properties
, did you concatenate your password and the Salesforce token ?
