9. Structure of CloverDX projects

In this chapter, we present only a brief overview of what happens when you are creating any CloverDX project.

This applies not only to local CloverDX project and CloverDX Examples project, but also to CloverDX Server project.

  1. Standard structure of all CloverDX projects

    Each of your CloverDX projects has the standard project structure (unless you have changed it while creating the project).

  2. The .classpath file

    This file defines the paths to .class and .jar files that can be loaded and used by transformation graphs.

  3. Workspace.prm file

    Each of your local or remote (Server) CloverDX projects contains the workspace.prm file (in the project folder) with basic information about the project.

Standard structure of all CloverDX projects

In the CloverDX perspective, there is a Project Explorer pane on the left side of the window. In this pane, you can expand the project folder. After that, you will be presented with the folder structure. There are subfolders for:

 For more information about parameters, see Parameters, and about their usage, see Using parameters.

Remember that using parameters in CloverDX ensures that such a graph, metadata or any other graph element can be used in any place without necessity of its renaming.

The .classpath file

The .classpath file defines the paths to .class and .jar files that can be loaded and used by transformation graphs.

The following configuration is reported as warning.

  • References to nearby projects (configured in project  Properties under Java Build Path).

  • Usage of non-standard classpath containers (project  Java build path under Libraries  Add Library).

  • Usage of classpath variables (project  Java build path under Libraries  Add Variable)

  • Usage of non-standard output folder. The trans is only accepted value.

If a classpath in a remote project contains reference to other sandbox, a warning on project level is displayed.

Workspace.prm file

You can look at the workspace.prm file by clicking this item in the Project Explorer pane and right-clicking and choosing Open With  CloverDX Parameters Editor from the context menu.

You can see the parameters of your new project.

The parameters of imported projects may differ from the default parameters of a new project.
