IntelliJ says "Warning: java: foo/bar/Baz.java uses unchecked or unsafe operations", but it doesn't say in which line it is referring to

Question

I am getting this warning:

When I click on the image, it just opens the associated Editor, but it doesn't say the line number where the warning is raised. I don't want to add @SuppressWarning("unchecked") on the whole class...

Any workaround/fix?

Answer 1

I'm not sure why your IDE does not show you generic warnings, but you can try to compile with

-Xlint:unchecked

to get more details.

Answer 2

To compile with -Xlint:unchecked in IntelliJ IDEA:

• Go to Settings dialog (Ctrl+Alt+S or ⌘ +, )
• Select Compiler > Java Compiler

• Add following into the field Additional command line parameters:

  -Xlint:unchecked

• Run your compile again

Answer 3

IntelliJ IDEA 15

A faster solution:

• Press Ctrl + Shift + A

• Type "Additional com" and press Enter:

  

• Type -Xlint:unchecked > OK

  

• Press Ctrl + Shift + F9 to recompile (or go to Build > Compile ... )

  • you can select a class / module from the project tree to specify what you want to be recompiled

• You will see the line and the column where the problem appeared

  E.g.: Warning:(5,27) java: unchecked ...

Answer 4

I don't yet have the reputation to comment, but to add to @ROMANIA_engineer's answer - if you're on a Mac, the shortcut is Shift-Command-A.

The menu entry is Help/Find Action.
