[news.eclipse.newcomer] Eclipse shell? CLI?

[Kai Grossjohann <kai@xxxxxxxxxxxxxx>]

Is there a plugin that provides a shell-like interface (CLI?) to
Eclipse?

By this I mean a window with a prompt, and then the user may enter
commands at that prompt that are then executed.  Completion should be
provided for command names and command arguments.  Also, a command
history should be provided for recalling past commands.

For instance, I could imagine a command "edit Java class" that accepts
a Java class name as argument and then opens the Java source file
editor on that class.

Or a command "build" that accepts a project name as argument and then
builds that project.

Or "search -i -pattern '*.java' -scope ws 'foo'" which does a file
search for the string foo, case-insensitively, in files matching the
pattern *.java in the whole workspace.
