Eclipse Workbench User Guide

Markers are objects that may be associated with Workbench resources.  There are many uses of markers in the Workbench.  The three main uses of markers in the Workbench are:

  • Tasks
  • Problems
  • Bookmarks

Markers are shown in a marker view (Tasks, Problems or Bookmark view) or on the marker bar in the editor area.

The following sections give more detail on each of these marker types.


A task marker represents a work item. There are two kinds of tasks:

  • Automatically-generated information associated with the resource
  • User specified tasks that may or may not be associated with a resource

Both of these task types appear in the Tasks view.


Problem markers represent invalid states and are categorized as follows..

  • Errors: Error markers are often used to indicate the source location of syntax or compilation errors.
  • Warnings: Warning markers indicate the source location of, for example, compilation warnings.
  • Information: Information markers indicate the source location of information only tasks.

Problems are shown in the Problems view.


Bookmarks place an anchor either at a specific line in a resource or on the resource itself. They are shown in the Bookmarks view.
