Aptana Studio 3 - Running on Server (Doesn't Work for Some Projects)

Question

I am able to "Run/Debug on Server" a new Rails project, created in Aptana.

However, "Run/Debug on Server" fails silently for an existing project.

I haven't been able to figure out why the behavior differs.

Here's what shows in the log.

I had the same problem. I don't know what happened but here is what I did to solve this:

1. Go to Preferences->Aptana Studio->Web Servers.
2. Click New.
3. Pick Rails server from a list.

In the dialog box: Enter name for the server (I'm not sure but it's probably better to put the exact name of the project you are setting server for - this is the same name that appears on the list below); Pick a project name from a list you want to configure the server for; Leave 0.0.0.0 and 3000 untouched.

Click OK & enjoy!
