Generate New Configuration not working

[andrewcole50]

To start off I'm new to adding and using packages with Sublime Text. I have Sublime Text 2 and when I go to Compile and Run Current Project it gives me the option to Generate New Configuration or Cancel. When I select Generate New Configuration nothing happens. I could make the file myself but I don't know where to put it so the compiler can find it. Suggestions?

I have the same question. When I mouse single left click to select Generate New Configuration nothing happens.I tried to create a file with the name "settings.sublime-javac" with the cotent as below:
{
"project_name" : "inheritance",
"output_dir" : "output",
"sources_dir" : "src",
"encoding" : "utf-8",
"resources" : [],
"libs" : [],
"entry_file" : "inheritance.java",
"entry_point" : "inheritance"
}

I then tried to put the file in "sublime text ... \Data\Packages\User" or my src folder. But it still asks me to generate new configuration. How is it supposed to work?
