Is there a way that the Local History can be configured to keep track of
changes to Java files that happen outside of Eclipse?
For example, I sometimes edit Java files outside of Eclipse in a text editor
and it would be nice if the local history would recognize those as external
changes. It only seems to keep track of changes made in Eclipse.
Thanks.

What John is saying is that currently the workspace doesn't hold the
"current" file contents in the local history. The local history is only
populated after changes are made in the workspace. This was a conscious
design decision.
Sequence of events:
- IFile.create() is called and contents have state A. (local history is
empty)
- IFile.setContents() is called with state B. State A is moved to local
history (pending flags and history store rules) and then the file's contents
are set on disk. (local history has one entry, state A)
We do not agressively add files to the local history when files are first
created. Consider the performance hits this behaviour would introduce. (some
people's workspaces have upwards to 100,000 resources...)
Additional comments can be found in bug 10589.
