IntelliJ IDE gives error when using Try-Catch with Resources

Question

I am attempting to use JDK 7's "try-catch with resources" statement; IntelliJ highlights my resource line, saying

Try-with-resources are not supported at this language level.

When I try to compile, I get:

java: try-with-resources is not supported in -source 1.6 (use -source 7 or higher to enable try-with-resources)

I checked that try-with-resources is enabled for my current project, and that my project is using JDK 7 (Library: C:\Program Files\Java\jdk1.7.0_11). Any ideas? I can't figure out what option to change (if that's even the issue).

Solution

Click on the File menu, open Project Structure, then under "Settings" there should be "Project". Within that tab, there'll be an SDK Settings option which specifies the language version you want to use.

See the JetBrains help page for more details ("Project language level").
