Eclipse Launch Configuration

Sometimes, the application has to be invoked with some arguments for other execution options to suit different purposes. For example, Internet Explorer supported the following options

(adopt from http://msdn.microsoft.com/en-us/library/ee330728(v=VS.85).aspx)

iexplore.exe [ [ -embedding ] [ -extoff ] [ -framemerging ] [ -k ] [ -noframemerging ] [ -nohangrecovery ] [ -private ] ] [ URL ]

If you are going to develop your program in Eclipse and want to test your application with different options, you may follow the instructions below.

  1. Open your project in Eclipse.
  2. In Project Explorer, find your project.
  3. Right-click and select Properties and then Properties Windows appears.
  4. In the menu on the left, click Run/Debug Settings.
  5. On the right, select a Launch configuration (by default there is at least one)
  6. Press Edit to change the configuration

As you can see, there are a number of configurations but we only focus on the settings in the Arguments tab.

  1. In the Arguments tab, input your arguments for the program. Each line is for one argument.
  2. If you do not want to use the default Working directory, unchecked Use default. This is useful if you want to open a file that is in the same directory as the executable. Suppose the executable named MyApp1. To specify the directory,
    1. For C++ project, very often, we change it from ${workspace_loc:MyApp1} to ${workspace_loc:MyApp1/Debug}
    2. For Java project, very often,  we change it from ${workspace_loc:MyApp1} to ${workspace_loc:MyApp1/bin}
