You need to install the jenv maven plugin, try the following command and reload your shell:

&gt;jenv enable-plugin maven

I had a similar problem. I got things running by prefixing all command with `jenv exec`:

    jenv exec mvn -version

Now, there&#39;s a new option how to set JAVA_HOME via jenv export plugin:

    jenv enable-plugin export

See https://github.com/gcuisinier/jenv/issues/44#issuecomment-233124185

If you have enabled the `maven` and `export` plugins, and still have problems, check that you don&#39;t have a `~/.mavenrc` file which is setting `JAVA_HOME`.

I&#39;ve been going through AWS DynamoDB docs and, for the life of me, cannot figure out what&#39;s the core difference between batchGetItem() and Query(). Both retrieve items based on primary keys from tables and indexes. The only difference is in the size of the items retrieved but that doesn&#39;t seem like a ground breaking difference. Both also support conditional updates.

In what cases should I use batchGetItem over Query and vice-versa?

What&#39;s the difference between BatchGetItem and Query in DynamoDB?

I know about the ampersand as a bit operation but sometimes I see it in front of variable names.  What does putting an `&amp;` in front of variables do?

What does an ampersand (&amp;) mean in the Swift language?

I had OSX with `Java 1.6` installed, and I just installed `jenv` along with `Java 1.7`:


    $ jenv local &#39;1.7&#39;
    $ jenv versions
      system
      1.6
      1.6.0.65
    * 1.7 (set by /Users/me/workspace/.java-version)
      1.7.0.79
      oracle64-1.6.0.65
      oracle64-1.7.0.79

`jenv` is doing its job, with `$ java -version` always working, showing 1.6 when I&#39;ve set it to 1.6, and 1.7 when I&#39;ve set it to 1.7:

    $ java -version
    java version &quot;1.7.0_79&quot;                    &lt;--------------------------------- YAY!!
    Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
    Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)

&lt;b&gt;... but maven is ignoring my settings:&lt;/b&gt;

I found [this SO question][1] where the guy just needed to hardcode his `JAVA_HOME` inside `.mavenrc`, but I don&#39;t want mine hard-coded (thus `jenv`!), and I don&#39;t have a `~/.mavenrc`, nor an `/etc/mavenrc`.

The version it&#39;s using seems to be from whatever&#39;s first on the `/usr/libexec/java_home` output, so in the short term I was able to get 1.6 back again by tweaking 1.7&#39;s `Info.plist` file (from [this SO post][2]), but that just means I get 1.6 instead of 1.7. 

Any ideas?

I have a `List&lt;Person&gt;`. I need to get a `List` from a property of `Person`.

For example, I have a `Person` class:

    class Person
    {
        private String name;
        private String birthDate;
        public String getName() {
            return name;
        }
        public String getBirthDate() {
            return birthDate; 
        }
        Person(String name) {
            this.name = name;
        }
    }

    List&lt;Person&gt; personList = new ArrayList&lt;&gt;();
    personList.add(new Person(&quot;David&quot;));
    personList.add(new Person(&quot;Joe&quot;));
    personList.add(new Person(&quot;Michel&quot;));
    personList.add(new Person(&quot;Barak&quot;));

I want to get a list of names with the `Stream` API, like this:

    List&lt;String&gt; names = personList.stream().somecode().collect(Collectors.toList());
    names.stream().forEach(System.out::println);

    #David
    #Joe
    #Michel
    #Barak

This code doesn&#39;t work:

    public class Main 
    {
        public static void main(String[] args) 
        {
	        List&lt;Person&gt; personList = new ArrayList&lt;&gt;();
            Person person = new Person(&quot;Иван&quot;);
            person.getFriends().addAll(Arrays.asList(&quot;Друг 1&quot;, &quot;Друг 2&quot;, &quot;Друг 3&quot;));
            personList.add(person);
            person = new Person(&quot;Федор&quot;);
            person.getFriends().addAll(Arrays.asList(&quot;Друг 4&quot;, &quot;Друг 5&quot;, &quot;Друг 6&quot;));
            personList.add(person);
            person = new Person(&quot;Алексей&quot;);
            person.getFriends().addAll(Arrays.asList(&quot;Друг 7&quot;, &quot;Друг 8&quot;, &quot;Друг 9&quot;));
            personList.add(person);
            person = new Person(&quot;Константин&quot;);
            person.getFriends().addAll(Arrays.asList(&quot;Друг 10&quot;, &quot;Друг 11&quot;, &quot;Друг 12&quot;));

            List&lt;String&gt; friens = personList.stream().map(e-&gt;e.getFriends()).collect(Collectors.toList());

            friends.stream().forEach(System.out::println);
            //Друг 1
            //Друг 2
            //Друг 3
            //Друг 4
            //...

        }
    }

    class Person
    {
        String name;
        List&lt;String&gt; friends;

        Person(String name) {
            this.name = name;
        }
        public String getName() {
            return name;
        }

        public List&lt;String&gt; getFriends() {
            return friends;
        }
    }

Android Studio - with Junit 4.12 “!!! JUnit version 3.8 or later expected:”

Android Studio is giving me a Gradle build error that looks like this:

    Error:(3, 22) compileSdkVersion android-22 requires compiling with JDK 7

Now it gives me these clickable prompts:

    Download JDK 7
    Select a JDK from the File System
    Open build.gradle File

And I have already downloaded and installed JDK 7. The problem is when I go to select it in the &quot;File System&quot; i can only find a directory named 1.6.0 JDK. Furthermore, the installation of JDK 7 skipped the bullet point where I would&#39;ve selected the install directory, so I&#39;m really not sure where it is. My java control panel says I have &quot;Java 7 Update 79&quot; so I&#39;m pretty sure I&#39;m close, I just need to tell android studio where it is. I also ran the `java -version` command in the terminal and it says my version is &quot;1.7.0_79&quot;.

Any help would be appreciated!



How to specify the JDK version in Android Studio?

I have a large file that contains a list of items.

I would like to create a batch of items, make an HTTP request with this batch  (all of the items are needed as parameters in the HTTP request). I can do it very easily with a `for` loop, but as Java 8 lover, I want to try writing this with Java 8&#39;s Stream framework (and reap the benefits of lazy processing).

Example:

    List&lt;String&gt; batch = new ArrayList&lt;&gt;(BATCH_SIZE);
    for (int i = 0; i &lt; data.size(); i++) {
      batch.add(data.get(i));
      if (batch.size() == BATCH_SIZE) process(batch);
    }
    
    if (batch.size() &gt; 0) process(batch);

I want to do something a long the line of
`lazyFileStream.group(500).map(processBatch).collect(toList())`

What would be the best way to do this?

I am trying to change MySql root password.

What I have done is below.

 1. Install MySql-5.7.6 ~ .dmg(Community Server) and workbench.
 2. Turn off the server on OSX System preferences.
 3. Access MySql with console. The command was `mysqld_safe --skip-grant`
 4. Execute `update user set password=password(&#39;1111&#39;) where user=&#39;root&#39;;` and got an error message --&gt; `ERROR 1054 (42S22): Unknown column &#39;password&#39; in &#39;field list&#39;`.

FYI, I did `use mysql;`.
So I did select query on user table and found password column actually does not exist. 

It is very weird. Is it possible that original user table does not have password column?

How can I change password, which does not exist?

Thanks for your answer :D

After upgrading from OS X Yosemite to OS X El Capitan Developer Preview, I tried to edit  **/System/Library/LaunchDaemons/ssh.plist** to change the default SSH port to a custom one. This is the process I&#39;ve been using for a couple of years.

The problem is that El Capitan doesn&#39;t allow me to change anything in this folder (not even with &quot;sudo&quot;). The folder and its files are marked as **&quot;restricted&quot;** when I list the contents with **&quot;ls -lO&quot;**. The same folder listing in previous versions of OS X does not show &quot;restricted&quot;.

Is this something new to OS X El Capitan? How can I edit files/folders that are **&quot;restricted&quot;**?

---

I found out this is due to a new feature introduced in **El Capitan** called **&quot;SIP&quot; (System Intregrity Protection)**.

Read more here: https://forums.developer.apple.com/thread/4731?q=SIP

Unfortunately, no one suggested a way of editing &quot;restricted&quot; files/folders without actually disabling SIP.

Usually on a Unix/Linux terminal when you press &lt;kbd&gt;Tab&lt;/kbd&gt; it will auto-complete until there are several options, and then it will list the options below for you to select. For example:

    cd he
    helpFolder/ helpMe/ heIsThere/
    cd help

With the Mac terminal, it forces you to press it twice to see options. I wondering if it&#39;s possible to change that setting to one &lt;kbd&gt;Tab&lt;/kbd&gt; press?

Mac Terminal Auto Complete

I want to install the MySQL client for the command line, not a GUI. I have searched over the web but only found instructions on installing the MySQL server.

How do I install command line MySQL client on mac?

I have an Android project with gradle. The problem is:
In `project` view I see few versions of `support-v4` libraries, for example `support-v4-21.0.3` and `support-v4-22.2.0`.

**But in `build.gradle` I don&#39;t have `support-v4` at all.**

But I have ~10 other dependencies in `build.gradle`. For example 
`appcompat-v7:22.2.0`. I can suggests that `appcompat-v7:22.2.0` depens on `support-v4-22.2.0` in maven dependencies and implicitly pulls it. But I have no ideas who pulls `support-v4-21.0.3`.

As far as I know all this libs will packed in my APK and increase weight of APK. 

So I have next questions:

 1. How to avoid library duplicates?
 2. How to see maven dependencies in Android Studio? 
 3. How detect which library require this library? For example which library require `support-v4-21.0.3` in my project?


gradle - library duplicates in dependencies

One of the dependencies declared in my project has a transitive dependency on `&#39;com.google.guava:guava:15.0&#39;`. But my application deployed on WAS/Weblogic doesn&#39;t work due to a CDI issue which has been fixed in `&#39;com.google.guava:guava:15.0:cdi1.0&#39;`. (same version, but with classifier) I need to tell gradle to use this jar during build and packaging. I am trying to figure on how we can ovrride this transitive dependency with a jar specific version classifier.

Tried the following approches:

 1. Added the dependency explicitly: `compile &#39;com.google.guava:guava:15.0:cdi1.0&#39;`. But both jars got included in the resultant WAR.
 2. Added the dependency explicitly and defined a resolution strategy:

        configurations.all {
            resolutionStrategy {
	            force &#39;com.google.guava:guava:15.0:cdi1.0&#39;
            }
        }
Even this didn&#39;t work.

 3. Defined a resolution strategy to check and change the version.

        configurations.all {
             resolutionStrategy.eachDependency { DependencyResolveDetails details -&gt;
    		     if (details.requested.group + &quot;:&quot; + details.requested.name == &#39;com.google.guava:guava&#39;) {
    	            details.useVersion &quot;15.0:cdi1.0&quot;
    	            //details.useTarget &quot;com.google.guava:guava:15.0:cdi1.0&quot;
    	        }
    	    }
        }
Even this didn&#39;t work.

Need your suggestions on how this issue can be tackled.

This is a snippet from my pom.xml.
I tried the following, but the profile was not activated.

    mvn clean install -Pdev1
    mvn clean install -P dev1

When I tried `mvn help:active-profiles` no profiles were listed as active.
If I set `&lt;activeByDefault&gt;` for `dev1` to `true`, and run  `mvn help:active-profiles`, it shows me the profile is activated.

    &lt;profile&gt;
            &lt;id&gt;dev1&lt;/id&gt;
            &lt;activation&gt;

Javadoc file is really absent in filesystem. Simultaneously, it is present in central repository. Why it was not downloaded and how to download it by force?

**UPDATE**

These options are ON already:

Have tried to recompile, close/open etc after setting them...
