Deprecated API usage

Reports usages of deprecated classes, fields, and methods. A quick-fix is available to automatically convert the deprecated usage, when the necessary information can be extracted from the Javadoc of the deprecated member.

Example:

  class Interesting {

    /**
     * @deprecated Use {@link #newHotness()} instead
     */
    @Deprecated
    public void oldAndBusted() {}

    public void newHotness() {}
  }
  class ElseWhere {
    void x(Interesting i) {
      i.oldAndBusted(); // deprecated warning here
    }
  }

After the quick-fix is applied:

  class Interesting {

    /**
     * @deprecated Use {@link #newHotness()} instead
     */
    @Deprecated
    public void oldAndBusted() {}

    public void newHotness() {}
  }
  class ElseWhere {
    void x(Interesting i) {
      i.newHotness();
    }
  }

By default, the inspection doesn't produce a warning if it's impossible or hard to avoid it. For example, the following code won't be reported:

  abstract class A { //library code
     @Deprecated
     abstract void m();
  }
  class B extends A { //project code
     @Override
     void m() {
        //doSmth;
     }
  }
