Question

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?

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.
