Suppress deprecated import warning in Java
In Java, if you import a deprecated class:
import SomeDeprecatedClass;
You get this warning: The type SomeDeprecatedClass is deprecated
Is there a way to suppress this warni开发者_StackOverflow社区ng?
To avoid the warning: do not import the class
instead use the fully qualified class name
and use it in as few locations as possible.
Use this annotation on your class or method:
@SuppressWarnings("deprecation")
Since Java 9, you might need to add:
@SuppressWarnings("removal")
If the class was annotated with something like:
@Deprecated(since = "3.14", forRemoval = true)
As a hack you can not do the import and use the fully qualified name inside the code.
You might also try javac -Xlint:-deprecation not sure if that would address it.
I solved this by changing the import to:
import package.*
then annotating the method that used the deprecated classes with@SuppressWarnings("deprecation")
Suppose that you are overriding/implementing an interface with a deprecated method (such as the getUnicodeStream(String columnLabel)
in java.sql.ResultSet
) then you will not get rid of deprecation warnings just by using the annotation @SuppressWarnings( "deprecation" )
, unless you also annotate the same new method with the @Deprecated
annotation. This is logical, because otherwise you could undeprecate a method by just overriding its interface description.
you can use:
javac FileName.java -Xlint:-deprecation
But then this will give you warnings and also tell you the part of the code that is causing deprecation or using deprecated API. Now either you can run your code with these warnings or make appropriate changes in the code.
In my case I was using someListItem.addItem("red color")
whereas the compiler wanted me to use someListItem.add("red color");
.
If @SuppressWarnings("deprecation")
is not working for you like for me. You can find exact squid number in sonar lint plugin. And then you can simply suppress warning: @SuppressWarnings("squid:CallToDeprecatedMethod")
