How do I compile with -Xlint:unchecked?

I'm getting a message when I compile my code:

Note: H:\Project2\MyGui2.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.


How do I recompile with
-Xlint:unchecked
?

Answer

Specify it on the command line for javac:

javac -Xlint:unchecked

Or if you are using Ant modify your javac target

  <javac ...>
    <compilerarg value="-Xlint"/>
  </javac> 

If you are using Maven, configure this in the maven-compiler-plugin

<compilerArgument>-Xlint:unchecked</compilerArgument>
