Common feature in many application is possibility to zoom text content by Ctrl + Mouse Wheel.

IntelliJ Idea has this feature, but it’s disabled by default.

You can enable zoom in few steps. Open Settings (Ctrl+Alt+S), search for “zoom“, select Editor.

Check the option “Change font size (Zoom) with Ctrl+Mouse Wheel“. Click OK and enjoy the zoom feature :-)

How to use PowerShell in IntelliJ Idea terminal instead of cmd

IntelliJ Idea has support for embedded terminal. That’s handy because you do not need to open extra window just for a terminal.

The default configuration of IntelliJ on Windows is installed with old-school cmd.exe. It’s quite easy to replace it by PowerShell.

Go to Settings (Ctrl+Alt+S). Search for word “terminal“. Select Tools – Terminal.

Change Shell path option from cmd.exe to


Press OK and start new Terminal window.

I recommend to use Dracula theme which is a little bit more readable than the white theme.

How to debug Gradle script

First of all: do not use daemon mode for debugging.

IntelliJ Idea is automatically spawning daemon when you start any Gradle task. You have to attach to remote process.

I wrote small “How to debug” based on info from forums.gradle.org.

You’ll need to set GRADLE_OPTS environment variable to:

-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005

Here is example in PowerShell:


$env:GRADLE_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005"

Configure Remote debugging in Idea:


You do not need to change anything in default configuration.

Now return to command line with your project and invoke task. Gradle will automatically stop and it waits for debugger.


Attach debugger


Here we go :-)


There is small limitation. You can stop code execution outside DSL e.g. in class method (line 3). You won’t be able to stop execution in Gradle DSL line 10.

You can download sample build script from Github.

IntelliJ Idea – Cordova – Default Activity not found! – solution

Situation: import Cordova project with support of Android platform to Intellij Idea. You’re not able to start emulator, because of strange error:

Default Activity not found!


One solution could be: go to File menu and choose Invalidate Caches /Restart.

This might not help.

The real problem is most likely in configuration of Android module. Open project configuration, select module and make sure that directory src is marked as Source.


Confirm module configuration and error message should disappear.
