| <h1> |
| Creating a new source folder with exclusion filter |
| </h1> |
| In a project that uses source folders, you can create a new folder to contain Java source code with exclusion patterns. Exclusion |
| patterns are useful if you have nested source folders. There are two ways to do it: |
| <ol> |
| <li>You don't already have an existing Java project in which you want to create a source folder with exclusion pattern.</li> |
| <li>You already have an existing Java project.</li> |
| </ol> |
| <h2>Starting from scratch</h2> |
| <ol> |
| <li>First follow the steps of the task "Creating a new source folder".</li> |
| <li>Once a first source folder is created, if you want to create another source folder that is nested inside the first one, you |
| need to use the exclusion pattern. |
| </li> |
| <li> |
| Open the <a href="../reference/ref-123.htm">Java Build Path</a> page <strong>(Project > Properties > Java Build Path)</strong> and click the <strong>Source</strong> tab. |
| </li> |
| <li> |
| Click <strong>Add Folder</strong>, select an existing source folder, and click <strong>Create New Folder</strong> to create a folder that is nested inside the first one. |
| </li> |
| <li>You will get a dialog saying that exclusion filter has been added to the first source folder. |
| <blockquote>NOTE: The trailing '/' at the end of the exclusion pattern <b>is required</b> to exclude the children of this folder. |
| The exclusion pattern follows the ant exclusion pattern syntax. |
| </blockquote> |
| </li> |
| <li> |
| Click <strong>OK</strong> and <strong>Finish</strong> when you are done. |
| </li> |
| </ol> |
| <h2>From an existing Java Project</h2> |
| <ol> |
| <li>Before you start, make sure that your project properties are enabled to handle exclusion filters in source folders. |
| </li> |
| <li> |
| In the Package Explorer, select the project where you want the new source folder to reside. |
| </li> |
| <li> |
| From the project's pop-up menu, select <strong>New</strong> > <strong>Source Folder</strong>. The New Source Folder wizard opens. |
| </li> |
| <li> |
| In the <strong>Project Name</strong> field, the name of the selected project appears. If you need to edit this field, you can either type a path or |
| click <strong>Browse</strong> to choose a project that uses source folders. |
| </li> |
| <li> |
| In the <strong>Folder Name</strong> field, type a name for the new source folder. If you choose a path that is nested |
| inside an existing source folder, you will see an error saying that you have nested source folders. |
| </li> |
| <li> |
| Check <strong>Update exclusion filters in other source folders to solve nesting</strong>. |
| </li> |
| <li> |
| Click <strong>Finish</strong> when you are done. |
| </li> |
| </ol> |
