eclipse中 linked resource的使用
一、关于linked resource
eclipse 中的linkded resources
是指存放在项目所在位置以外某个地方的文件或者文件夹；这些特定的资源必须有一个项目作为他们的父资源。linkded
resources可以用来给项目添加某些资源，这些资源因为某些原因必须被报春到项目以外的某个地方。
你可以使用linked resources来覆盖在workspace中的其他资源；从而使得一个项目的资源可以出现在另外一个项目中；这意味着，一个地方的改变可以使另外一个地方的资源同时发生改变；删除一个资源副本，会导致两个地方的资源同时被删除。
删除linked resources不会导致资源从文件系统中删除，但是删除linked folder下的资源，则会导致资源从文件系统中被删除。
二、创建linked resource
1）.创建一个linked folder
- In one of the navigation views, right-click the project where you want to create the new folder.
- From the pop-up menu, select New > Folder.
- Specify the name of the folder as it will appear in the workbench. This name can be different from the name of the folder in the file system.
- Click Advanced.
- Check Link to folder in the file system.
- Enter a file system path, or click Browse to select a folder in the file system.
- Click Finish.
To create a linked file, follow the same steps as above, except choose New > File instead of New > Folder in the context menu.
Linked resource locations can also be specified relative to a variable. This makes it easier to share projects containing linked resources with other team members, since it avoids hard-coded absolute file system paths that may vary from one machine to the next.
To define a linked resource relative to a path variable, do the following after step 5 above:
- Click the Variables button.
- In the resulting dialog, select an existing path variable or create a new one.
- If the chosen variable defines the exact path of the linked resource, click OK. Otherwise, click Extend to specify a file or folder below the location described by the path variable, then click OK.
- Click Finish.
Tip: The Window > Preferences > General > Workspace > Linked Resources preference page also allows you to define path variables.
Note that, once you create a linked resource you will not be able to change the link target path that you entered in step 6. or 8. above.
