I have a toy Java project set up with Gradle in IntelliJ IDEA 13.1.2. It compiles and runs fine, but the IDE highlights ‘google’ in
as red and warns “Cannot resolve symbol ‘google'”. Any idea how to fix it?
I have tried 1) deleting
.idea/ and re-creating the project in IntelliJ IDEA, and 2) re-importing project from the manually created Gradle configuration file
build.gradle, but to no avail.
It turns out that the depended packages need to be separately specified in IntelliJ IDEA in addition to
build.gradle and explicitly added as a dependency. Namely,
com.google.guavapackage following the instruction in documentation — I picked
com.google.guavapackage in the project settings. See the documentation instruction “Configuring Module Dependencies and Libraries”.
