How to stop IntelliJ truncating output when I run a build?

Intellij Idea

Intellij Idea Problem Overview

When I run our build from IntelliJ it pumps out a lot of debugging.

But it gets truncated in the Run console.

Can I make IntelliJ preserve more output?
Or, preferably, all of it?

By a popular request Override console cycle buffer size setting was added to the UI 9/14/16:

Override console cycle buffer size

Original answer for older versions:

Edit your IDEA_HOME\bin\idea.properties file, and increase this setting:

#-----------------------------------------------------------------------
# This option controls console cyclic buffer: keeps the console output size not higher than the specified buffer size (Kb). Older lines are deleted.
# In order to disable cycle buffer use idea.cycle.buffer.size=disabled
idea.cycle.buffer.size=1024

then restart IntelliJ.

This can (now) be edited in the Intellij IDEA settings.

Intellij IDEA Settings: Console

This has probably been in Intellij IDEA for a while, and certainly is as of Intellij IDEA 15.

Solution 3 - Intellij Idea

The problem increasing the console cylce buffer size is that you are likely to run out of heap space, and then you will need to bump up the max heap size. For an app that generates a very large amount of output it probably won't help as you will not have enough physical memory.

I would suggest instead that you capture the console output in a file.

With IntelliJ 11 (on the Mac at least), this setting is configured instead in Info.plist:

IDEA_HOME/Contents/Info.plist

There should already be a value there so just modify it instead of adding a new one.

Solution 5 - Intellij Idea

You could use this shortcut

Ctrl + Shift + A

then search "Override console cycle buffer size" to get to the settings.

Solution 6 - Intellij Idea

If you are using saved configurations to start your app, make sure this option is disabled: "Emulate terminal in output console". With this option enabled, the output would be always cut after a few hundred lines. Without it, I think the option described in the other answers is respected.

Accepted answer did not work for me (IntelliJ IDEA 2021.2 Mac). What did work was increasing "Terminal scrollback buffer size" in Preferences/Advanced Settings.

If you picked this option, IDEA also cuts the output. img
