I don&#39;t believe there is, nor would I think it&#39;s a good idea.

From my understanding, what you&#39;re aiming to achieve is have a commons-like component, that will be used for several mojos.  This requires the current Maven session to be passed in &amp; used to subsequently pass back a value.

The way Maven works however, is that it runs goals from plugins in an almost container-like environment.  Each plugin is allowed to act within a particular [Maven Phase][1], as defined by the &lt;code&gt;&amp;lt;executions /&amp;gt;&lt;/code&gt;.  This allows Maven to separate the complexities of building, testing, checking, deploying etc. etc.  Calling &lt;code&gt;mvn clean install&lt;/code&gt;, unless I&#39;m mistake, is two separate executions, one to run the &lt;code&gt;clean&lt;/code&gt; [build lifecycle][1], followed by the &lt;code&gt;install&lt;/code&gt;.

It is therefore not safe to assume that the &lt;code&gt;MavenSession&lt;/code&gt; and subsequent &lt;code&gt;MavenExecutionRequest&lt;/code&gt; represent the same instance used in a previous call.  &lt;code&gt;clean&lt;/code&gt; is a separate call, whose logic shouldn&#39;t be maintained in a new session.

So, what I&#39;m essentially saying, is that whilst having a common plexus component is a good practice, particularly to maintain consistency across your mojos, it is right practice (almost [ioc][2]), to provide the appropriate session each time.


I hope that&#39;s the answer you&#39;re looking for.  Rather long, but to understand why you need to provide the session, think &lt;code&gt;Maven&lt;/code&gt;.

I have a top level `UIViewController` that contains a `UITableView`.  The top level `UIViewController` instantiates a `NavigationController`, and pushes another `UIViewController` onto the `NavigationController`.  I.E. we push into a new, second view.  This second view has the usual &quot;Back&quot; button in the upper left hand corner to allow you to navigate back to the top level view.

Is it possible, when navigating back to the top level view from the second view, to redraw the `UITableView` in the top level view, using data generated in the second view, by calling `cellForRowAtIndexPath` in the top level and if so, how does one do this?

I currently have a paid app in the store. Apple have not allowed a &#39;lite&#39; version to be submitted as well, so I have no choice but to update the current paid version to a freemium (with in app purchase) model.  I have the problem of not loosing functionality for v1 users that have purchased the app the first time round.

Is there any way to determine if an application have been updated from a previously installed version so I can unlock the paid parts of the app?

I created a Plexus component to house common logic for several Mojos I want to create. I have been able to pass information like `localRepository` and project from the Mojo (and test cases).

I was wondering if there is a way to get the `MavenSession` or `MavenExecutionRequest` from within the component without having to pass them as parameters from a Mojo. I know my component will be running from a Maven Mojo.

I&#39;m using Maven 2 in this instance.

I&#39;ve got an sbt (Scala) project that currently pulls artifacts from the web. We&#39;d like to move towards a corporate-standardized Nexus repository that would cache artifacts. From the Nexus documentation, I understand how to do that for Maven projects. But sbt obviously uses a different approach. (I understand Ivy is involved somehow, but I&#39;ve never used it and don&#39;t understand how it works.)

How do I tell sbt and/or the underlying Ivy to use the corporate Nexus repository system for all dependencies? I&#39;d like the answer to use some sort of project-level configuration file, so that new clones of our source repository will automatically use the proxy. (I.e., mucking about with per-user config files in a dot-directory is not viable.) 

Thanks!

how do I get sbt to use a local maven proxy repository (Nexus)?

I thought I was an experienced Maven user, but I am having a mental block on how to do this!

I&#39;ve been able to use the Maven sql plugin to drop, create, and install a schema in a database via plugin executions I&#39;ve defined and bound to the `pre-integration-test` phase.

However, now I&#39;d like to use that same sql plugin to insert some sample data whenever I want from the command line -- that is, not bound to any lifecycle goal.  There are a few different sets of sample data, so I&#39;d like to define a few different executions.

But is there a way to run one of these executions from the command line by using the execution ID perhaps?

Maven: How to change path to target directory from command line?

Single Page Javascript Application
----------

I have built a sophisticated ajax-driven single page webapp that uses a RESTful backend web service serving JSON. The javascript is split into many different files, each file representing some sort of feature or component.

While the service has been in *alpha* testing, I&#39;ve just be serving all these files separately without minification. But now that I&#39;d like to launch a *beta* version, I really need to combine files, minify them, and version them. I want to add this to my build process, using Maven.

Javascript File Types
-------------
I&#39;m using the following &quot;types&quot; of javascript files, of which #3 and #4 are my concerns:

1. External files, such a jquery and jquery-ui served from the Google CDN. Rarely change these versions, can be handled manually.
2. Jquery plugins that I&#39;m hosting myself, such as fullcalendar or ui-layout. Again, I rarely update these to new versions and can handle it manually.
3. Application-wide javascript code. Custom javascript that is spread across many files and can change occasionally. All of these files need to be loaded for the app to work.
4. Feature-specific javascript code. Custom javascript that is loaded on demand when a specific feature is requested. This code can change quite frequently and is not loaded at startup.

Build Objectives
-----

I&#39;d like to do the following during my build process:

* Concatenate all type 3 javascript files together, minify them, and save as a single file with a version number. For instance: `app-2.0.6.min.js`, where 2.0.6 is the maven project version.
* All type 4 files should be individually minified and saved as separate files with version numbers in the name. For instance: `feature-abc-56ab32de29.min.js`, where 56ab32de29 is the version number of that specific file.
* Update HTML files with `&lt;script&gt;` tags to point to javascript files with the correct version numbers.
* Update Javscript files that load type 4 feature javascript files to point to the right versions.

Questions
-----

* Is there a maven plugin that will assist with the concatenation?

* Is there a maven plugin that will assist with the minification? Ideally, I&#39;d like to use Google Closure Compiler, but would work with others if simpler.

* Is there a maven plugin that will assist with the versioning? 

* Is there a way to have the type 4 javascript files have independent version numbers? Ideally, if a file doesn&#39;t change between version 2.0.5 and 2.0.6, there is no need for users to download a new version and their cached version would work fine. I&#39;m using GIT for source control, so would there be a way to use a file&#39;s GIT hashcode for versioning?

* Is there a solution that will compress the javascript that is inline in regular HTML files without killing the HTML?

* Is there a solution that will compress and version my CSS files as well?

I have created a minimal maven project with a single child module in eclipse helios.

In the src/test/resources folder I have put a single file &quot;install.xml&quot;. In the folder src/test/java I have created a single package with a single class that does:

      @Test
      public void doit() throws Exception {
        URL url = this.getClass().getClassLoader().getResource(&quot;install.xml&quot;);
        System.out.println(url.getPath());
    
      }

but when I run the code as a junit 4 unit test I just get a NullPointerException. This has worked fine a million of times before. Any ideas?

I have followed this guide:

http://www.fuyun.org/2009/11/how-to-read-input-files-in-maven-junit/

but still get the same error.

This is my current project structure:

    pom.xml
    /src
      /main
        /resources

          /META-INF
            persistence.xml

I have very similar configuration params in both files (`hibernate.cfg.xml` and `persistence.xml`), which looks strange, but this is what I saw in many online examples and tutorials. I can&#39;t understand why do I need to have two files. Is it possible to work just with one? Please explain.

ps. For example, should I declare `hibernate.dialect` in both files, or just one will be enough? If so, which one to use?

When creating a custom component in android it is often asked how to create and pass through the attrs property to the constructor.

It is often suggested that when creating a component in java that you simply use the default constructor, i.e. 

    new MyComponent(context);

rather than attempting to create an attrs object to pass through to the overloaded constructor often seen in xml based custom components. I&#39;ve tried to create an attrs object and it doesn&#39;t seem either easy or at all possible (without an exceedingly complicated process), and by all accounts isn&#39;t really required. 

My question is then: What is the most efficient way of construction a custom component in java that passes or sets properties that would have otherwise been set by the attrs object when inflating a component using xml?





How to pass custom component parameters in java and xml

First, I am new to Java EE, came from a strong ASP .NET development background.
I have gone through the net, and I might miss this but it seems like there is no simple and straight-to-the-point tutorials on how I could connect backing bean class to a JSF components.

A good example is like this, currently I am trying to create a JSF page where there is a set of links as menu bar and a set of forms. What I am planning to do is, when clicking a link, a particular form will be rendered. 

In ASP.NET, I could easily retrieve the element and then set the attribute to be displayable. I am wondering if there is easy way (heck, even any way) to do this in JSF.

The forms is already in the page, it is just a matter of setting the &quot;render&quot; attribute to true when I click a particular link.

Conditionally displaying JSF components

There are lot of materials out there differentiating `value` attribute and `binding` attribute in JSF.

I&#39;m interested in how both approaches differ from each other. Given:

    public class User {
        private String name;
        private UICommand link;

        // Getters and setters omitted.
    }

&lt;!-- language: lang-xhtml --&gt;

    &lt;h:form&gt;
        &lt;h:commandLink binding=&quot;#{user.link}&quot; value=&quot;#{user.name}&quot; /&gt;
    &lt;/h:form&gt;

It is pretty straight forward what happens when a `value` attribute is specified. The getter runs to return the `name` property value of the `User` bean. The value is printed to HTML output.

But I couldn&#39;t understand how `binding` works. How does the generated HTML maintain a binding with the `link` property of the `User` bean?

Below is the relevant part of the generated output after manual beautification and commenting (note that the id `j_id_jsp_1847466274_1` was auto-generated and that there are two hidden input widgets).
I&#39;m using Sun&#39;s JSF RI, version 1.2.

&lt;!-- language: lang-html --&gt;

	&lt;form action=&quot;/TestJSF/main.jsf&quot; enctype=&quot;application/x-www-form-urlencoded&quot;
	    id=&quot;j_id_jsp_1847466274_1&quot; method=&quot;post&quot;  name=&quot;j_id_jsp_1847466274_1&quot;&gt;
    	&lt;input name=&quot;j_id_jsp_1847466274_1&quot; type=&quot;hidden&quot; value=&quot;j_id_jsp_1847466274_1&quot;&gt;
	    &lt;a href=&quot;#&quot; onclick=&quot;...&quot;&gt;Name&lt;/a&gt;
    	&lt;input autocomplete=&quot;off&quot; id=&quot;javax.faces.ViewState&quot; name=&quot;javax.faces.ViewState&quot;
	    	type=&quot;hidden&quot; value=&quot;-908991273579182886:-7278326187282654551&quot;&gt;
	&lt;/form&gt;

Where is the `binding` stored here?

How does the &#39;binding&#39; attribute work in JSF? When and how should it be used?

I have just started working with Angular 2. 

I was wondering what are the differences between components and directives in Angular 2?


What is the difference between component and directive?

This is driving me nuts, I&#39;m under the gun and can&#39;t afford to spend another whole day on this.

I am trying to manually set a control value (&#39;dept&#39;) within the component, and it&#39;s just not working - even the new value logs to console properly.

Here is the FormBuilder Instance:
```typescript    
initForm() {
  this.form = this.fb.group({
    &#39;name&#39;: [&#39;&#39;, Validators.required],
    &#39;dept&#39;: [&#39;&#39;, Validators.required],
    &#39;description&#39;: [&#39;&#39;, Validators.required],
  });
}
```
This is the event handler that receives the selected dept:
```typescript
deptSelected(selected: { id: string; text: string }) {
  console.log(selected) // Shows proper selection!
 
  // This is how I am trying to set the value
  this.form.controls[&#39;dept&#39;].value = selected.id;
}
```
Now when the form is submitted and I log out `this.form` the field is still blank!  I&#39;ve seen other ppl use `updateValue()` but this is beta.1 and I don&#39;t see that as a valid method to call on the control.

I have also tried to call `updateValueAndValidity()` with no success :(.

I would just use `ngControl=&quot;dept&quot;` on the form element, like I&#39;m doing with the rest of the form but its a custom directive/component.
```html
&lt;ng-select
  [data]=&quot;dept&quot;
  [multiple]=&quot;false&quot;
  [items]=&quot;depts&quot;
  (selected)=&quot;deptSelected($event)&quot; &lt;!-- This is how the value gets to me --&gt;
  [placeholder]=&quot;&#39;No Dept Selected&#39;&quot;&gt;
&lt;/ng-select&gt;
```

Manually Set Value for FormBuilder Control

I&#39;m reading about Maven right now and everywhere in a text I see this word (mojo). I approximately understand what it means, but I would not refuse from a good explanation. I tried to google, but found only non-maven explanations.
