How can I set a breakpoint for when variable changes in Eclipse?

Question

Is there a way, using the eclipse debugger, to break any time a particular variable is written to?

The only thing I can think of is to manually set a breakpoint at every reference but my codebase is several million lines and I really don't want to do that.

Answer 1

You can set a watchpoint at the desired variable. Simply click on the line where the variable is declared, and select Run -> Toggle Watchpoint.

The watchpoint can break on either accessing the variable, modifying the variable, or both.

Answer 2

Use the Expressions View functionality from the Eclipse Debugger.
