How to count lines of Java code using IntelliJ IDEA?

Quick and dirty way is to do a global search for '\n'. You can filter it any way you like on file extensions etc.

Ctrl-Shift-F -> Text to find = '\n' -> Find.

Edit: And 'regular expression' has to be checked.

In the past I have used the excellently named MetricsReloaded plugin to get this information.

You can install it from the JetBrains repository.

Once installed, access via: Analyze -> Calculate Metrics...

The Statistic plugin worked for me.

To install it from Intellij:

File - Settings - Plugins - Browse repositories... Find it on the list and double-click on it.

Access the 'statistic' toolbar via tabs in bottom left of project screen capture of statistic toolbar, bottom left

OLDER VERSIONS: Open statistics window from:

View -> Tool Windows -> Statistic
