| <h1>NetBeans Platform File Type Tutorial Using Maven</h1> |
| |
| <p>This document demonstrates how to create a NetBeans module |
| from a Maven archetype |
| and build and install the module in NetBeans IDE or any other application |
| on the NetBeans Platform. |
| In this tutorial, you will create a module project |
| that when installed enables you to recognize a new type of file |
| in your projects. The module also creates a menu action that |
| is available when the user right-click a file conforming |
| to the new file type. |
| </p> |
| |
| <p>This document is based on the Ant-based <a href="https://platform.netbeans.org/tutorials/nbm-filetype.html">NetBeans File Type Tutorial</a> |
| and can be used to learn some of the differences between using Ant and Maven to develop NetBeans modules. |
| After you understand the differences, you can easily proceed through other |
| tutorials on the <a href="https://netbeans.org/kb/trails/platform.html">NetBeans Platform Learning Trail</a>.</p> |

| <p><strong class="notes">Note:</strong> You do not need to download Maven because it |
| is bundled with the IDE. Optionally, use your own download of Maven, in which |
| case use the Options window to configure your Maven settings.</p> |
| |
| <p>Before starting this tutorial you may want to familiarize yourself with |
| the following introductory Maven documentation:</p> |
| <ul> |
| <li><a href="http://wiki.netbeans.org/MavenBestPractices">Best Practices for Maven in NetBeans IDE</a></li> |
| <li><a href="http://www.sonatype.com/books/maven-book/reference/introduction.html">Chapter 1. Introducing Apache Maven</a> |
| (from <a href="http://www.sonatype.com/books/maven-book/reference/public-book.html">Maven: The Definitive Guide</a>)</li> |
| </ul> |
| |
| <!-- =================================================================== --> |
| <!-- +++++++++++++++ Configuring Maven +++++++++++++++++++++++++++++++++ |
| |
| <h2><a name="config"></a>Using Maven with the IDE</h2> |
| <p>If this is your first Maven project you will want to familiarize yourself with the Maven configuration settings |
| and the Maven Repository Browser.</p> |
| |
| <div class="indent"> |
| <a name="config1"></a> |
| <h3>Configuring Maven Options</h3> |
| <p>You can use the Maven tab in the Options window to configure the behavior of Maven in the IDE and to check |
| that your configuration is correct.</p> |
| |
| <ol> |
| <li>Select the Miscellaneous category in the Options window and click the Maven tab.</li> |
| <li>Specify the location of your local Maven installation (requires 2.0.9 or newer).</li> |
| <li>Check that the location of the local Maven repository is correct.</li> |
| <li>Click OK.</li> |
| </ol> |
| <p>In most cases, if your Maven configuration is typical the information in the Options window should already be correct.</p> |
| |
| <p class="notes"><strong>Note.</strong> Maven support is activated as part of the Java SE feature set. |
| If the Maven tab is not available in the Options window, confirm that Java SE is activated by creating a Java application.</p> |
| |
| <h3><a name="config2"></a>Viewing the Maven Repositories</h3> |
| <p>The artifacts that are used by Maven to build all your projects are stored in your local Maven repository. |
| When an artifact is declared as a project dependency, the artifact is downloaded to your local repository |
| from one of the registered remote repositories.</p> |
| |
| <p>The NetBeans repository and several well-known indexed Maven repositories are registered and listed in the Repository Browser window by default. |
| The NetBeans repository contains most of the public artifacts necessary for you to build your project. |
| You can use the Maven Repository Browser to view the contents of your local and remote repositories. |
| You can expand the Local Repository node to see the artifacts that are present locally. |
| The artifacts listed under the NetBeans repository nodes can be added as project dependencies, but not all of |
| them are present locally. They are only added to the Local Repository when they are declared as project |
| dependencies.</p> |
| |
| <p>To open the Maven Repository Browser:</p> |
| <ul> |
| <li>Choose Window > Other > Maven Repository Browser from the main menu.<br/> |
| <img src="../images/tutorials/maven-quickstart68/maven-nbm-netbeans-repo.png" alt="Screenshot of Maven Repository Browser" title="Screenshot of Maven Repository Browser" class="margin-around b-all" /> |

| <!-- ++++++++++++++++++++++ Creating the Module ++++++++++++++++++++++++ --> |
| |
| <h2><a name="01"></a>Creating the Module Project</h2> |
| <p>In this section you create a NetBeans module project from a Maven archetype.</p> |
| <ol> |
| <li><p>Open the New Project wizard and choose NetBeans Module in the Maven category:</p> |
| <p><img src="../images/tutorials/maven-single/71/pic1.png" alt="Module wizard 1" title="Module wizard 1" class="margin-around b-all" /> |
| </p> |
| <p>Click Next.</p></li> |
| <li><p>Type <strong>AbcFileTypeSupport</strong> in Project Name and specify |
| a location for storing the project:</p> |
| <p> |
| <img src="../images/tutorials/maven-single/71/pic2.png" alt="Module wizard 2" title="Module wizard 2" class="margin-around b-all" /> |
| </p> |
| <p>Click Next. Specify the NetBeans API version you want to use. Click Finish.</p> |
| </li> |
| </ol> |
| <p>When you click Finish, the IDE creates the AbcFileTypeSupport project:</p> |
| <p><img src="../images/tutorials/maven-single/71/pic4.png" alt="Module wizard 4" title="Module wizard 2" /> |
| </p> |
| <p>If you look in the POM, shown above, you can see that Maven will use the |
| <tt><a href="http://maven.apache.org/plugins/maven-jar-plugin/">maven-jar-plugin</a></tt> to build the JAR and the |
| <tt><a href="http://mojo.codehaus.org/nbm-maven-plugin/">nbm-maven-plugin</a></tt> will package the JAR as a |
| NetBeans Module (<tt>nbm</tt>).</p> |

| <h2><a name="01b"></a>Recognizing the File Type</h2> |
| |
| <p>In this section you will use the New File Type wizard to create the files for |
| recognizing a new file type named <tt>.abc</tt>.</p> |
| |
| <ol> |
| <li><p>Right-click the project node in the Projects window and |
| choose New > File Type. Click Next.</p></li> |
| <li><p>In the File Recognition panel, type <strong>text/x-abc</strong> |
| for the MIME Type and <strong>.abc .ABC</strong> for the Filename |
| Extension: |
| </p> |
| <p><img src="../images/tutorials/maven-single/71/pic5.png" alt="Module wizard 1" title="Module wizard 1" class="margin-around b-all" /> |
| </p> |
| <p>Click Next.</p> |
| </li> |
| <li><p>Type <strong>Abc</strong> as the Class Name Prefix. |
| Click Browse and select a |
| 16x16 pixel image file as the new file type's icon.</p> |
| <p class="tips">If you don't have an image |
| available, just save this image <tt><a href="../images/tutorials/maven-crud/abc16.png">abc16.png</a></tt> ( <img src="../images/tutorials/maven-crud/abc16.png" alt="16x16 icon image" title="16x16" /> ) |
| to your system and select the image after clicking Browse.</p> |
| <p><img src="../images/tutorials/maven-single/71/pic6.png" alt="Module wizard 1" title="Module wizard 1" class="margin-around b-all" /> |
| </p> |
| <p>Click Finish.</p> |
| </li> |
| </ol> |
| |
| <p>When you click Finish, the IDE creates the files shown below:</p> |
| <p><img src="../images/tutorials/maven-single/71/pic7.png" alt="Module wizard 1" title="Module wizard 1" /></p> |
| |
| <p class="tips">For more details on the files that the IDE created, see |
| <a href="http://wiki.netbeans.org/DevFaqDataObject">What is a DataObject</a> and the section on |
| <a href="nbm-filetype.html#recognizing">Recognizing Abc Files</a> in the |
| Ant-Based <a href="nbm-filetype.html">File Type Integration Tutorial</a>.</p> |
| |
| <!-- =================================================================== --> |
| <!-- ++++++++++++++++++++++ Running the Module ++++++++++++++++++++++++ --> |
| <h2><a name="02"></a>Building and Running the Project</h2> |
| |
| <p>To install the module, you first need to build and run it.</p> |
| <ol> |
| <li><p>Right-click the project node and choose Build.</p></li> |
| <li><p>Right-click the project node and choose Run. |
| The IDE launches with the new module installed. |
| To confirm that the new module is working correctly, create a |
| new project and then use the New File wizard |
| to create an <tt>abc</tt> file:</p> |
| <p><img src="../images/tutorials/maven-single/71/pic8.png" alt="Module wizard 1" title="Module wizard 1" /></p> |
| |
| <p>For example, you can create a simple Java application |
| and then open the New File wizard and |
| choose the Empty Abc file type in the Other category.</p> |
| <p class="tips">When you create the new file, specify a source package if you want to see the file in the Projects window. |
| By default the wizard for the new file type will create the file at the root level of the project.</p> |
| </li> |
| <li><p>After you create the new abc file you can see that the file is displayed in the Projects window with the icon for the file type. |
| If you open the file in the editor you can see that |
| the contents of the new file were generated from the file template.<br/> |
| </p> |
| <p><img style="border:1px solid black" src="../images/tutorials/maven-single/71/pic9.png" alt="Module wizard 1" title="Module wizard 1" /></p> |
| <p>Click the "Visual" tab and you will see the GUI panel |
| created by the New File Type wizard:</p> |
| <p><img style="border:1px solid black" src="../images/tutorials/maven-single/71/pic91.png" alt="Module wizard 1" title="Module wizard 1" /></p> |
| </li></ol> |
| <p>You can see that your file type is now recognized by the application. In |
| the next section, we'll create a new action for our file type, which |
| will be available when the user right-click on a file |
| conforming to the type in the Projects window.</p> |
| |
| <!-- =================================================================== --> |
| <!-- +++++++++++++++++++++++ Adding an Action ++++++++++++++++++++++++++ --> |
| <h2><a name="03"></a>Adding an Action for the File Type</h2> |
| <p>In this section you will add an action that can be invoked from |
| the popup menu when the user right-clicks the node of a file |
| conforming to your new file type.</p> |
| |
| <ol> |
| <li><p>Right-click the AbcFileTypeSupport project and choose New > Action. |
| In the Action Type panel, select Conditionally Enabled and |
| type <strong>AbcDataObject</strong> for |
| the Cookie Class, which specifies the type that |
| needs to be in the Lookup for the Action to be enabled:</p> |
| <p><img style="border:1px solid black" src="../images/tutorials/maven-single/71/pic92.png" alt="Module wizard 1" title="Module wizard 1" /></p> |
| <p>Click Next.</p> |
| </li> |
| <li><p>Select Edit in the Category drop-down list and deselect Global Menu Item. |
| Select File Type Context Menu Item and select <strong>text/x-abc</strong> in the Content |
| Type drop-down list:</p> |
| <p><img style="border:1px solid black" src="../images/tutorials/maven-single/71/pic93.png" alt="Module wizard 1" title="Module wizard 1" /></p> |
| <p>Click Next.</p> |
| </li> |
| <li><p>Type <strong>MyAction</strong> as the Class Name |
| and <strong>My Action</strong> as the Display Name:</p> |
| <p><img style="border:1px solid black" src="../images/tutorials/maven-single/71/pic94.png" alt="Module wizard 1" title="Module wizard 1" /></p> |
| <p>Click Finish.</p> |
| <p>When you click Finish, <tt>MyAction.java</tt> is created in the <tt>com.mycompany.abcfiletype</tt> source package:</p> |
| |
| <pre class="examplecode">package com.mycompany.abcfiletypesupport; |
| |
| import java.awt.event.ActionEvent; |

| } |
| |
| public void actionPerformed(ActionEvent ev) { |
| // TODO use context |
| } |
| |
| }</pre></li> |
| |
| |
| <li><p>Let's now make the Action a bit more meaningful. We'll add some code for the action. |
| In this example you will add some code that uses <tt>DialogDisplayer</tt> to open a dialog box |
| when the action is invoked from the popup menu.</p> |
| <p>Modify the <tt>actionPerformed(ActionEvent ev)</tt> method in <tt>MyAction.java</tt> to open a dialog when My Action is invoked.</p> |
| <pre class="examplecode">@Override |
| public void actionPerformed(ActionEvent ev) { |
| <strong>FileObject f = context.getPrimaryFile(); |
| String displayName = FileUtil.getFileDisplayName(f); |
| String msg = "This file is " + displayName + "."; |
| NotifyDescriptor nd = new NotifyDescriptor.Message(msg); |
| DialogDisplayer.getDefault().notify(nd);</strong> |
| }</pre> |
| </li> |
| <li><p>Fix the missing import statements (Ctrl-Shift-I) |
| and then confirm that your import statements are as shown below:</p> |
| |
| <pre class="examplecode">package com.mycompany.abcfiletypesupport; |
| |
| import java.awt.event.ActionEvent; |
| import java.awt.event.ActionListener; |

| |
| |
| |
| </li> |
| |
| <li><p>You can now try out the module to confirm that the new action works correctly.</p> |
| <p class="notes"><strong>Note.</strong> To run the module you will first need to clean and build the module.</p> |
| <p>When you right-click on a node of the <tt>abc</tt> file type you will see that My Action is one of the items in the popup menu.</p> |
