How to Use Jetbrains' Tools for Free

This guideline is for mac OS and uses IntelliJ IDEA as an example.

  • Just search ‘jetbrains intellij download’ in google. Download and install.
  • Just search ‘jetbra checker’ in google. Choose one of the valid links and click jetbra.zip. Extract the jetbra folder.
  • This step is necessary because mac OS checks the app that’s installed with package from the internet before it’s opened at the first time.
  • Copy the jetbra folder to the folder /Applications/IntelliJ IDEA.app/Contents/.
  • Open the idea.vmoptions file with the following command vim /Applications/IntelliJ\ IDEA.app/Contents/bin/idea.vmoptions

  • Add the following lines to the end of the file

    -javaagent:/Applications/IntelliJ IDEA.app/Contents/jetbra/ja-netfilter.jar=jetbrains
    --add-opens=java.base/jdk.internal.org.objectweb.asm=ALL-UNNAMED
    --add-opens=java.base/jdk.internal.org.objectweb.asm.tree=ALL-UNNAMED
    
  • Back to the website where you download jetbra and find IntelliJ IDEA card.
  • Pause your mouse cursor over the hidden message and copy the activation code.
  • Open the Intellij IDEA again and activate the license.
  • Enjoy!
