java - Why can't i import the jdk.javadoc.doclet package?

I wanted to make a custom doclet for JavaDoc and i initially tried to use the com.sun.javadoc package for this application. I was successfully able to create a doclet and use it with JDK8, but doing this with JDK12 gives me a warning that this class is deprecated and would be soon out of support.

I tried the same doclet with JavaDoc on another computer with OpenJDK15 (running java --version gave me the following output:)

openjdk 15.0.1 2020-10-20
OpenJDK Runtime Environment (build 15.0.1+9-18)
OpenJDK 64-Bit Server VM (build 15.0.1+9-18, mixed mode, sharing)

and it is really out of support :( I could not use it and it gave me a message saying that this doclet is not supported.

After some research, i found that the new jdk uses the jdk.javadoc.doclet API to create doclets. i created a basic doclet using the above class that actually does nothing, just implemented all methods and tried to compile, but the compiler gave me an error saying that package jdk.javadoc.doclet does not exist.

I use IntelliJ as my IDE but it doesn't show any error through it's IntelliSense. IntelliJ believes that the package exists and even provides me code highlighting for the methods in the classes of that package.

Please make sure that the JDK in your development IDE, ie Eclipse, Intellij, uses the same one as your PATH variable does. You can verify this by checking the properties of the corresponding settings of the IDE. Probably it might so happen that you have multiple version of JDK installed on your PC and the one your development ide uses is different than the one from the system one. Having such a problem will create problems inside the IDE, when compiling your source code.
