Chapter 2. Predefined ProjectsThe predefined projects capability allows you to quickly access pre-configured project repositories. For example training labs or golden reference projects or projects that you commonly use. DVT searches for predefined projects in the directory indicated by the
$DVT_PREDEFINED_PROJECTS system variable. In order to support directories spread on the disk, DVT also scans all directories indicated by any other system variable whose name starts with
$DVT_PREDEFINED_PROJECTS_EXT_.
For example, if you installed DVT from a distribution, by default
$DVT_PREDEFINED_PROJECTS points to
$DVT_HOME/predefined_projects. This is a project repository that you can use to explore the DVT features without the initial effort of configuring a project.
At any time, if you wish to change the default location, you just need to point
$DVT_PREDEFINED_PROJECTS to another location. Or add another pre-configured projects repository by pointing
$DVT_PREDEFINED_PROJECTS_EXT_MY_NEW_REPOSITORY to it.
For example if you installed DVT as a plug-in on top of an existing Eclipse installation,
$DVT_PREDEFINED_PROJECTS is unset. But you can download the predefined projects separately, and point the system variable to the folder where you extracted the predefined projects.
Opening a Predefined Project
To open a predefined project use the
Predefined Project Wizard by selecting
File > New > Example... then
DVT Examples > DVT Predefined Project.
You can also open the wizard from the
DVT Project Wizard by clicking on the Predefined Projects link:
Preferences
In the wizard's main window you can select the
predefined project and the
target directory. A copy of the selected project will be placed in the target directory. Keep in mind that:
The target directory
must not be a parent of or inside of the
eclipse workspace path
The target directory
must be writable
The selected project
must not exist in the current workspace
Quick filter - by project name; Available predefined projects; A short description of the selected project; If you want to change the default target directory (by default is the
$HOME/dvt_predefined_projects_target );
Override target directory (if it already exists) A message dialog will pop up, with info about all
$DVT_PREDEFINED_PROJECTS &
$DVT_PREDEFINED_PROJECTS_EXT_* environment variables (indicates the directories where DVT scans for predefined projects); See the picture below:
If all the settings are correct, click
Finish.
