Building a Java program
A build command compiles workbench resources. A build command can be triggered in different ways:
-
Building automatically: If auto build is turned on
(Project > Build Automatically, or Window > Preferences > General > Workspace > Build automatically), then an
incremental build occurs every time you save a modified workbench resource.
-
Building manually: You can perform a manual build using a keyboard shortcut, a project's pop-up menu or the Project menu in the menu bar.
