Intellij IDEA-如何在项目中查找软件包使用情况

Question

I am looking at a project's maven pom file with a lot of dependencies and trying to find out if a particular dependency is used or not. Is there a way in Intellij IDEA to find all import statements that import any class from a particular package?

Answer 1

I'm working with IntelliJ IDEA 14 UE.

1. switch to the view "Project"
2. in the tree view, go to the node "External Libraries"
3. search the particular library (=dependency) and open the node
4. select a package within this library
5. in the popup menu of this package, click "Find usages". Alternatively, press Alt+F7 (Windows)

Answer 2

I am not aware of a way to do it directly in IntelliJ but you can always use the analyse goal of the maven-dependency-plugin .

Here is a link to a nice example of the plugin.
