==== Using a Trigger File
If you work with an IDE that continuously compiles changed files, you might prefer to trigger restarts only at specific times.
To do so, you can use a "`trigger file`", which is a special file that must be modified when you want to actually trigger a restart check.
Changing the file only triggers the check and the restart only occurs if Devtools has detected it has to do something.
The trigger file can be updated manually or with an IDE plugin.
To use a trigger file, set the `spring.devtools.restart.trigger-file` property to the path of your trigger file.
NOTE: Any update to the file file will trigger a check, but restart only actually occurs if Devtools has detected it has something to do.
To use a trigger file, set the `spring.devtools.restart.trigger-file` property to the name (excluding any path) of your trigger file.
The trigger file must appear somewhere on your classpath.
For example, if you have a project with the following structure:
[indent=0]
----
src
+- main
+- resources
+- .reloadtrigger
----
Then your `trigger-file` property would be:
[source,properties,indent=0]
----
spring.devtools.restart.trigger-file=.reloadtrigger
----
Restarts will now only happen when the `src/main/resources/.reloadtrigger` is updated.
TIP: You might want to set `spring.devtools.restart.trigger-file` as a <<using-boot-devtools-globalsettings,global setting>>, so that all your projects behave in the same way.
Some IDEs have features that save you from needing to update your trigger file manually.
https://spring.io/tools[Spring Tools for Eclipse] and https://www.jetbrains.com/idea/[IntelliJ IDEA (Ultimate Edition)] both have such support.
With Spring Tools, you can use the "`reload`" button from the console view (as long as your `trigger-file` is named `.reloadtrigger`).
For IntelliJ, you can follow the https://www.jetbrains.com/help/idea/spring-boot.html#configure-application-update-policies-with-devtools[instructions in their documentation].
