com.intellij.openapi.diagnostic.Logger debug() statements are not visible in the console Follow
I'm sure it is something very obvious that I'm missing but I can't figure out how to make my plugin's logger.debug() statements visible in the IntelliJ console. My plugin project is Gradle-based and I run the plugin from within IntelliJ by calling the runIdea Gradle task. If I replace logger.debug() with System.out.println(), I can see the output in the console, but obviously I don't want to leave this kind of code there :)

Making logger.debug() visible in standard output is not better than keeping System.out.println() in your code, you don't need it.
Logger.debug() is logging messages to idea.log of started IDE instance. You can find log files under `<sandbox_directory>/system/log/` directory. Sandbox directory is configured by gradle-intellij-plugin and points to `<project_dir>/build/idea-sandbox` by default.
The most convenient way to see the logs of running IDE is to add a tab to Run tool window with content of idea.log file:
To do this just add log file in Gradle run configuration settings:
By default IDE logging severity is INFO. To override this, use `Help | Debug Log Settings` action of IDE that you run via `runIdea` task
Thank you very much, sir! This is exactly what I was looking for! The only problem now is I can't figure out the log category name to add to the Debug Log Settings list. Is it a class name, package name or anything else? I instantiate the logger as follows:
and MySillyAction has package com.foo.bar. So what should I add to the Debug Log Settings:
or anything else?
I tried all the combinations so far but I don't see my debug output.
According to the sources, Logger adds '#' prefix when you creating a logger for class (https://github.com/JetBrains/intellij-community/blob/master/platform/util/src/com/intellij/openapi/diagnostic/Logger.java#L79). So please try `#com.foo.bar.MySillyAction`, hope this works
And it works!
Damn, I wish all this was properly documented, but I guess I'm asking too much, am I? :)
Thanks very much again!
I am glad to have found out this question and the response from Alex.
But I think I am still not clear on one things.
I have a util class which has a method with Debug statement.
Everytime an action runs, I want to make sure that debug statement is logged somewhere:
So I added this to the class
and then in the running idea instance -> Help -> Debug log settings, I added
But when I run that action from the running IDE, I do not see the log in the idea.log file
When I compile the project, the above debug statement appears in build/build.log
Though I am getting the debug statement, I would really like that this statement comes in the idea.log on executing that action and not on the compilation of the project and in build.log
Any idea what am I missing here.
Sorry for a late response.

Not really, do you see any other debug log statements in idea.log while running IDE from IDE? Please verify that logging severity is set to `all` (see the first screenshot in the thread, the combobox is nearby the search field).
