How to set javadoc of external libraries in IntelliJ Idea?


In IntelliJ Idea I set offline javadoc of Java SDK in Project structure -> SDKs -> Documentation Paths and add path to documentation folder. Whenever I want to see tooltip I just press Ctrl + Q to see offline documentation for a symbol at caret. But it works only for Java SDK. For example - I am using servlet-api.jar library, I downloaded servlet-api javadoc, but I cannot import it to IntelliJ Idea in any way. I tried to add it to SDKs -> Documentation Paths but it didn't work. Is it a way how to import offline javadoc of other libraries to see tooltips easily?

This attempt doesn't work. enter image description here


Solution

  • When the project type is not Maven or Gradle, adding Javadoc for particular library is done via settings in Project Structure(Ctrl + Shift + Alt + S). Add library by choosing Java from option. Then add particular JavaDoc for that library. Then choose apply. To see tooltip window not only by pressing Ctrl + Q but also by hover over symbol, choose File -> Settings -> Editor -> General -> and check Show quick documentation on mouse move.
