问题:

In previous versions of IDEA I was able to set how many days back the Local History feature would keep the changes in the source files. For some reason, I cannot find this in IDEA 11.1.3, and local history is kept less about a day back. I think I went through all the settings, but can't find where I can increase this value. Does anyone know where I might find it?

Thanks!

回答1:

Modify bin\idea.exe.vmoptions (idea.vmoptions on Linux, Info.plist on Mac), add the following line:

-DlocalHistory.daysToKeep=5

It was the only configurable option removed from the settings user interface.

Another way is to use Help | Find Action, type Registry in the box, ensure that Include non-menu actions option is enabled, select the Registry result from the list, press Enter:

Note that the default value is 5 working days.

Also you should know that maximum value of this setting localHistory.daysToKeep is 23 (working days).
If you try set this value more than 23, history just will saved nothing at all (after restart IDEA)!
I discovered this by myself by experimental way =)
