Configuring the project build order

You can instruct the IDE to build certain projects before others. If a given project refers to another project, the IDE builds that project first.
Note: Setting the build order doesn't necessarily cause the IDE to rebuild all projects that depend on a given project. You must rebuild all projects to ensure that all dependencies are resolved.
To manually configure the project build order:
  1. From the main menu, select Window > Preferences .
  2. In the left pane, expand General, expand Workspace, and select Build Order.

  3. Disable the Use default build order option.
  4. Select a project from the list, then click the Up or Down buttons to position the project where you want it to appear in the build order list.
  5. When you're done, click Apply, then OK.
