Reflective access to non-existent or not visible class member

Reports reflective access to fields and methods that don't exist or aren't visible.

Example:

  Field stringHashField() throws NoSuchFieldException {
    return String.class.getField("hash");
  }

After the quick-fix is applied:

  Field stringHashField() throws NoSuchFieldException {
    return String.class.getDeclaredField("hash");
  }

Locating this inspection

By ID

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.

Via Settings dialog

Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.

Settings or Preferences | Editor | Inspections | Java | Reflective access

With a final class, it's clear if there is a field or method with the specified name in the class.

With non-final classes, it's possible that a subclass has a field or method with that name, so there could be false positives. Use the inspection's settings to get rid of such false positives everywhere or with specific classes.
