You can simply use:


    mvn --settings YourOwnSettings.xml clean install

or 

    mvn -s YourOwnSettings.xml clean install



I just find it very difficult, It was still not working for me. Then I checked the comments and understood that you have to override global settings. Pointed by 
@khmarbaise
I am adding this in a new answer.

    mvn -gs /local-path/settings.xml clean install
    
    mvn --global-settings /local-path/settings.xml clean install



I&#39;m trying to make a calculator of growth rate (`Double`) that will round the result to the nearest Integer and recalculate from there, as such:

    let firstUsers = 10.0
    let growth = 0.1
    var users = firstUsers
    var week = 0
    
    
    while users &lt; 14 {
        println(&quot;week \(week) has \(users) users&quot;)
        users += users * growth
        week += 1
    }

but I&#39;ve been unable so far.

*EDIT*
I kinda did it like so:

    var firstUsers = 10.0
    let growth = 0.1
    var users:Int = Int(firstUsers)
    var week = 0
    
    
    while users &lt;= 14 {
        println(&quot;week \(week) has \(users) users&quot;)
        firstUsers += firstUsers * growth
        users = Int(firstUsers)
        week += 1
    }

Although I don&#39;t mind that it is always rounding down, I don&#39;t like it because `firstUsers` had to become a variable and change throughout the program (in order to make the next calculation), which I don&#39;t want it to happen.

I&#39;m finding that I need to update my page to my scope manually more and more since building an application in angular.

The only way I know of to do this is to call `$apply()` from the scope of my controllers and directives. The problem with this is that it keeps throwing an error to the console that reads  :
&gt;Error: $digest already in progress

Does anyone know how to avoid this error or achieve the same thing but in a different way?

I have an application with maven as a build tool.

I am using maven profiles to set up different properties from different profiles.

What i would like to do is that all active profiles in maven will be ported to spring active profiles as well so i can reference them in bean signature (`@profile`). but i am not sure how to do it.

for example: consider the following maven setup

&lt;!-- language: lang-xml --&gt;

 	&lt;profiles&gt;
		&lt;profile&gt;
			&lt;id&gt;profile1&lt;/id&gt;
			&lt;activation&gt;
				&lt;activeByDefault&gt;true&lt;/activeByDefault&gt;
			&lt;/activation&gt;
			&lt;properties&gt;
			&lt;/properties&gt;
		&lt;/profile&gt;
		&lt;profile&gt;
			&lt;id&gt;profile2&lt;/id&gt;
			&lt;properties&gt;
			&lt;/properties&gt;
		&lt;/profile&gt;
		&lt;profile&gt;
			&lt;id&gt;development&lt;/id&gt;
			&lt;activation&gt;
				&lt;activeByDefault&gt;true&lt;/activeByDefault&gt;
			&lt;/activation&gt;
     		&lt;properties&gt;
			&lt;/properties&gt;
		&lt;/profile&gt;
		&lt;profile&gt;
			&lt;id&gt;production&lt;/id&gt;
			&lt;properties&gt;	
			&lt;/properties&gt;
		&lt;/profile&gt;
	&lt;/profiles&gt;

assuming i run maven with out specifying any other profiles i would like for spring to have `profile1` and  `development` as active profiles.

I am currently setting the port via a `jetty.xml` file and I&#39;ve been trying to figure out from the new documentation how to actually define an `httpConnector` through the Maven plugin&#39;s configuration. The docs on Eclipse&#39;s site seem a bit vague on it and I&#39;ve been trying to figure this out for a while, thus ending up using a `jetty.xml`. I&#39;d like to find out the proper way to do this now.

Right now I have a library project, say project Foo that depends on a library like OkHttp. 


Now, Foo has a Maven buildstep that generates an AAR and pushes it up to a public place.

Now lets say I have project B, we&#39;ll call it Bar. Bar is an Android application, and Bar depends on Foo.

Well, I have that. However, when I make a call to a `public static` function in Foo from Bar that calls OkHttp, I get this message:

    java.lang.NoClassDefFoundError: com.squareup.okhttp.OkUrlFactory
                at com.foo.sdk.utils.OkHttpStack.&lt;init&gt;(OkHttpStack.java:15)

Is such a thing possible? Or will Bar need to manually depend on OkHttp as well as any other dependencies Foo has? 

Can an AAR include transitive dependencies?

I am trying to run rspec for Ruby on Rails.  I am running Rails 4.1.1.  I have installed the gem, have established a spec folder with some tests.  I have created a directory through `$ rails g rspec:install`  

I tried to create a testing database through `$ rake db:test:prepare` but it throws this error message:

    WARNING: db:test:prepare is deprecated. The Rails test helper now maintains your test 
    schema automatically, see the release notes for details.

So I ended up looking at [this stack overflow post](https://stackoverflow.com/questions/23351783/when-i-ran-bundle-exec-rake-testprepare-it-errored-out-but-bundle-exec-rake), and of the two options, the one that worked was:

    rake db:schema:load RAILS_ENV=test 

So, **now I need to run rspec**. 

When I run `$ rspec spec` from the command line I get this error:

    /Users/myname/.rbenv/versions/2.1.1/lib/ruby/2.1.0/rubygems/core_ext/
    kernel_require.rb:55:in `require&#39;: cannot load such file -- rails_helper (LoadError)

How do I resolve this so that I can start running tests?

I&#39;m trying to open a directory in sublime Text 3.

I can launch sublime from the command line using the `subl` command.

The help text show the following:

    Sublime Text build 3059
    
    Usage: subl [arguments] [files]         edit the given files
       or: subl [arguments] [directories]   open the given directories
       or: subl [arguments] -               edit stdin
    
    Arguments:
      --project &lt;project&gt;: Load the given project
      --command &lt;command&gt;: Run the given command
      -n or --new-window:  Open a new window
      -a or --add:         Add folders to the current window
      -w or --wait:        Wait for the files to be closed before returning
      -b or --background:  Don&#39;t activate the application
      -s or --stay:        Keep the application activated after closing the file
      -h or --help:        Show help (this message) and exit
      -v or --version:     Show version and exit
    
    --wait is implied if reading from stdin. Use --stay to not switch back
    to the terminal when a file is closed (only relevant if waiting for a file).
    
    Filenames may be given a :line or :line:column suffix to open at a specific
    location.
    

Thus to open a directory I should be able to use the following 

`subl ./folder_name`

but that does not work for me. Sublime does open (with a empty new document) and I cannot see the folder in the side bar.

Am I doing it wrong...

BTW. I&#39;m using the fish shell with the &#39;Oh my fish&#39; Add-on (I have also added the sublime add- on)...

I want to call a Ruby script from the command line, and pass in parameters that are key/value pairs.

Command line call:

    $ ruby my_script.rb --first_name=donald --last_name=knuth

my_script.rb:

    puts args.first_name + args.last_name

What is the standard Ruby way to do this? In other languages I usually have to use an option parser. In Ruby I saw we have `ARGF.read`, but that does not seem to work key/value pairs like in this example.

[OptionParser][1] looks promising, but I can&#39;t tell if it actually supports this case.

I noticed that the compiler won&#39;t let me override a stored property with another stored value (which seems odd):

    class Jedi {
        var lightSaberColor = &quot;Blue&quot;
    }
    
    
    class Sith: Jedi {
        override var lightSaberColor = &quot;Red&quot; // Cannot override with a stored property lightSaberColor
    }

However, I&#39;m allowed to do this with a computed property:

    class Jedi {
        let lightSaberColor = &quot;Blue&quot;
    }
    
    
    class Sith: Jedi {
        override var lightSaberColor : String{return &quot;Red&quot;}
    
    }

Why am I not allowed to give it another value?

Why is overriding with a stored property an abomination and doing it with a computed one kosher? What where they thinking?

Xcode 6.3.  Within a class implementing UITextFieldDelegate protocol, I would like to override touchesBegan() method to possibly hide the keyboard.  If I avoid a compiler error in the function spec, then there is a complier error trying to read the &quot;touch&quot; from the Set or NSSet, or else the   super.touchesBegan(touches , withEvent:event) throws an error.  One of these combinations compiled in Xcode 6.2!  (So where is documentation to Swift &quot;Set&quot; and how to get an element from one?)

     override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {

            }
            super.touchesBegan(touches , withEvent:event)
        }

As I understand it, the `override` keyword states that a given declaration implements a base `virtual` method, and the compilation should fail if there is no matching base method found.

My understanding of the `final` keyword is that it tells the compiler that no class shall override this `virtual` function.

So is `override final` redundant? [It seems to compile fine][1]. What information does `override final` convey that `final` does not? What is the use case for such a combination?

What&#39;s the simplest way to store the application secrets (passwords, access tokens) for a Python script? I thought it&#39;d be a `*.yml` file like in Ruby but surprisingly I found that it wasn&#39;t the case. So what is it then? What are the most simplest solutions?

**NOTE** The keyword here is &quot;default&quot;.  I know I can hit escape and the default behavior gets aborted.  I don&#39;t want to hit the escape key every time the IDE thinks it knows what I want.  I didn&#39;t have to do this in 2013.

**ADDENDUM 2** It seems I&#39;m still having difficulty communicating what I&#39;m after here.  What I want to happen is _nothing_ when I press the space bar... I just want a space character to show up on my screen.  The only time I want the IDE to actually insert a suggestion is when I hit the tab bar.  I hope that&#39;s clearer?

This is driving me nuts.  2013 and before allowed you to set completion characters (maybe that was resharper?) but in 2015 I see no way to stop the default behavior of autocomplete.

For example, say I have a class `Foo`, but I don&#39;t have the namespace specified already, yet I have a class `FooBar` in one of the specified namespaces, if I type:

    public void DoSomething(Foo// &lt;-- then a space)

...it automatically puts `FooBar`.  How the heck do I turn off this behavior?

I should mention that I still want AutoComplete, just on tab though.

I&#39;d like to be able to sync my VS Code user settings (File &gt; Preferences &gt; User Settings) to the cloud somehow so I can easily share them between multiple installations, as in Windows 10 and Visual Studio.

Is there a supported way of doing this? Direct support in Code would be great, but otherwise being able to move my settings.json location to a Dropbox or OneDrive folder would work too.

I&#39;m looking specifically for a way of doing this automatically and silently. Manually exporting/importing is too cumbersome and isn&#39;t what I&#39;m looking for.
