`./gradlew`

Your directory with gradlew is not included in the PATH, so you must specify path to the gradlew.  `.` means &quot;current directory&quot;. 

Also, if you don&#39;t have the *gradlew* file in your current directory:

You can install gradle with [homebrew][1] with the following command:

    $ brew install gradle

As mentioned in [this answer][2]. Then, you are not going to need to include it in your path (homebrew will take care of that) and you can just run (from any directory):

    $ gradle test

I have a maven multi-module project and I&#39;m using jacoco-maven for code coverage reports. Some classes should not be reported, as they&#39;re Spring configuration and I&#39;m not interested in them.

I have declared the maven-jacoco plugin as follow:


	&lt;plugin&gt;
	&lt;groupId&gt;org.jacoco&lt;/groupId&gt;
	&lt;artifactId&gt;jacoco-maven-plugin&lt;/artifactId&gt;
	&lt;version&gt;0.7.2.201409121644&lt;/version&gt;
	&lt;configuration&gt;
		&lt;outputDirectory&gt;${project.reporting.outputDirectory}/jacoco-ut&lt;/outputDirectory&gt;
		&lt;exclude&gt;some.package.*&lt;/exclude&gt;
		&lt;exclude&gt;**/*Config.*&lt;/exclude&gt;
		&lt;exclude&gt;**/*Dev.*&lt;/exclude&gt;
		&lt;exclude&gt;some/package/SomeClass.java&lt;/exclude&gt;
	&lt;/configuration&gt;
	&lt;executions&gt;
		&lt;execution&gt;
			&lt;goals&gt;
				&lt;goal&gt;prepare-agent&lt;/goal&gt;
			&lt;/goals&gt;
		&lt;/execution&gt;
		&lt;execution&gt;
			&lt;id&gt;report&lt;/id&gt;
			&lt;phase&gt;prepare-package&lt;/phase&gt;
			&lt;goals&gt;
				&lt;goal&gt;report&lt;/goal&gt;
			&lt;/goals&gt;
		&lt;/execution&gt;
		&lt;execution&gt;
			&lt;id&gt;post-unit-test&lt;/id&gt;
			&lt;phase&gt;test&lt;/phase&gt;
			&lt;goals&gt;
				&lt;goal&gt;report&lt;/goal&gt;
			&lt;/goals&gt;
		&lt;/execution&gt;
	&lt;/executions&gt;
	&lt;/plugin&gt;


The problem is that when I execute `mvn clean verify` jacoco still reports classes that should have been excluded as my xml configuration points out. How can I configure it properly?

First I&#39;ll sketch my project:

For my internship I need to add functionality to an existing system. A 3rd party client must be able to access data from AX Webservices once he is authorised by the user via OAuth2. I understand that I need to make a &#39;proxy web service&#39; whereto the client can make its calls and that calls the AX services but I am a bit unsure about the OAuth2 part. Most tutorials and guides are about using ASP.NET&#39;s Identity for Facebook or Google-logins. I do not need that, I need to use existing credentials so I need to make my own OAuth2 service. 

I find it hard to find tutorials, guides or explanations on this. I understand OAuth2 and what needs to be done, but I have never done such a thing before and find it hard to start. The closest thing to what I need that I found is this [github repo link][1], but the solution does not build.

What I had in mind is making an ASP.NET MVC Website where clients (3rd parties) can register themselves and acquire their Client ID&#39;s. With ASP.NET API I wanted to create the API that take the required tokens and parameters, and then access the Dyn AX services.

Is this correct or am I entirely wrong? Any help or links regarding building your own oauth2 server/service would be nice.

I have a very simple question. I am brand new to Mac and I am trying to get my Java project moved over to my new Mac. The project has a Gradlew file that I thought I could run from the command line to build and run on any machine. When I do gradlew from the command line (in the location of the gradlew file) it says gradlew not found. Am I missing something on how to run a command from a bash shell?

Can I add `null` values to an `ArrayList` even if it has a generic type parameter?

Eg.

    ArrayList&lt;Item&gt; itemList = new ArrayList&lt;Item&gt;();
    itemList.add(null);

If so, will

    itemsList.size();

return 1 or 0?


If I can add `null` values to an `ArrayList`, can I loop through only the indexes that contain items like this?

    for(Item i : itemList) {
       //code here
    }

Or would the for each loop also loop through the null values in the list?

Why does the Java API use `int`, when `short` or even `byte` would be sufficient?

Example: The [`DAY_OF_WEEK`][1] field in class [`Calendar`][2] uses `int`.


  [1]: https://docs.oracle.com/javase/8/docs/api/java/util/Calendar.html#DAY_OF_WEEK
  [2]: https://docs.oracle.com/javase/8/docs/api/java/util/Calendar.html

If the difference is too minimal, then why do those datatypes (`short`, `int`) exist at all?

Why does the Java API use int instead of short or byte?

Until Java 7 there was an area in JVM memory called **PermGen**, where JVM used to keep its classes. In [Java 8][1] it was removed and replaced by area called **Metaspace**. 
 
What are **the most important differences** between PermGen and Metaspace?

The only difference I know is that `java.lang.OutOfMemoryError: PermGen space` can no longer be thrown and the VM parameter `MaxPermSize` is ignored.

I tried to create a **JavaFX** application in IntelliJ Idea IDE but I got compile error that said:

&gt; java: package javafx.application does not exist. 

I have changed the Project SDK and the Project Language Level to Java 8, reloaded the project but it didn&#39;t help. Then I checked if JavaFX plugin was enabled in the settings.

The search on Google and StackOverflow didn&#39;t give me more ideas of what is wrong.
Thank for any help in advance.

I am trying to get the difference between the current date as `NSDate()` and a date from a PHP `time();` call for example: `NSDate(timeIntervalSinceReferenceDate: 1417147270)`. How do I go about getting the difference in time between the two dates. I&#39;d like to have a function that compares the two dates and `if(seconds &gt; 60)` then it returns minutes, `if(minutes &gt; 60)` return hours and `if(hours &gt; 24)` return days and so on. 

How should I go about this?

EDIT: The current accepted answer has done exactly what I&#39;ve wanted to do. I recommend it for easy usage for getting the time between two dates in the form that that PHP `time()` function uses. If you aren&#39;t particularly familiar with PHP, that&#39;s the time in seconds from January 1st, 1970. This is beneficial for a backend in PHP. If perhaps you&#39;re using a backend like NodeJS you might want to consider some of the other options you&#39;ll find below.

Is there any native Swift way for any (at least integer) number to get its hexadecimal representation in a string? And the inverse. It must not use Foundation. For example the String class has a function

    func toInt() -&gt; Int?

which converts a string representing an integer to its Int value. I am looking for something similar, using the hex strings. I know this is easily implementable, but if Swift has it there already it would be better. Otherwise if you made already an extension of String and Int to achieve the following:

    let anHex = &quot;0xA0&quot;
    if let anInt = anHex.toInt() {
       println(anInt)               // prints 128
       println(anInt.toHexString()) // prints &quot;0xA0&quot;
    }

I know it isn&#39;t rocket science but in case please share it. 

PS: This is similar to [this question](https://stackoverflow.com/q/24229505/4243998), the difference is that it was very related to the Foundation framework, while I am not using it in my code (nor I am importing anything else) and for now I&#39;d like to keep it in this way, also for learning purposes.

is there is a way to negate the &quot;if let&quot; in swift? 
This looks silly to me:

        if let type = json.type  {
            
        } else {
            XCTFail(&quot;There is no type in the root element&quot;)
        }

I can&#39;t use XCTAssertNotNil, because json.type is a enum.

    enum JSONDataTypes {
        case Object
        case Array
        case Number
        case String
    }

Thanks a lot

Many will found that this is repeating questions but i have gone through all the questions before asked about this topic but none worked for me.

I want to print full path name of the certain file format using ls command so far i found chunk of code that will print all the files in the directory but not full path.


    for i in io.popen(&quot;ls /mnt/mediashare/net/192.168.1.220_STORAGE_1d1b7&quot;):lines() do
      if string.find(i,&quot;%.*$&quot;) then 
         print(i) 
      end
    end

this will print out all the file in root diractory and subdiratory.

Output:

**EDIT:**
I have used this all but its not working with my code in LUA.

when I used with my code it displays wrong directory

        end
      end

is not finding files in &quot;/mnt/mediashare/net/192.168.1.220_STORAGE_1d1b7&quot; insted its prints the machines root directory files.
    


List file using ls command in Linux with full path

I need to check if the recipient username is in file */etc/passwd* which contains all the users in my class, but I have tried a few different combinations of *if* statements and *[grep][1]* without success. The best I could come up with is below, but I don&#39;t think it&#39;s working properly.

My logic behind it is that if the *grep* is null, the user is invalid.

    send_email()
    {
      message=
      address=
      attachment=
      validuser=1
      until [ &quot;$validuser&quot; = &quot;0&quot; ]
        do
        echo &quot;Enter the email address: &quot;
        read address
        if [ -z grep $address /etc/passwd ]
          then
        validuser=0
        else
            validuser=1
        fi
        echo -n &quot;Enter the subject of the message: &quot;
