When debugging IntelliJ code, search idea.log using these patterns:
Log Levels:
FINE = debug level (from LOG.debug { })INFO = info level (from LOG.info())Category Format:
#<abbreviated.package.path>.<ClassName>
Example: com.intellij.openapi.wm.impl.status.IdeStatusBarImpl → #c.i.o.w.i.s.IdeStatusBarImpl
Search Examples:
# Debug logs from IdeStatusBarImpl
grep "FINE - #c.i.o.w.i.s.IdeStatusBarImpl" idea.log
# Info logs from IdeStatusBarImpl
grep "INFO - #c.i.o.w.i.s.IdeStatusBarImpl" idea.log
# All logs from a class
grep "#c.i.o.w.i.s.IdeStatusBarImpl" idea.log
When fixing issues where a user-facing entry point (script, command, API) doesn't behave as expected:
Pluginize a Product DSL module set by hand-writing a wrapper plugin module next to its feature modules. Use when promoting modules out of an aggregate module set (e.g. `essential`, `ide.common`) into a bundled plugin so products can include or omit them through normal plugin wiring, when updating bundled plugin registration for such a wrapper, or when fixing tests whose plugin loading logs show a missing wrapper plugin for a former module set.

Extract an optional dependency from a plugin module into a new content module. Use when making a library dependency optional by separating integration code into its own module.
