IntelliJ IDEA 7 features Eclipse interoperability, enabling the mixed development team benefit from the use of both IDE. Projects can be imported to or from Eclipse, or synchronized so that the code base is shared between two environments.

• Import (creating IntelliJ IDEA .iml and .ipr files from existing Eclipse projects)
• Export (creating Eclipse project files from existing IDEA .iml files)
• Synchronization (module dependencies stored directly in Eclipse-compatible .classpath file)
• 

Maven build configurations can also be imported to IntelliJ IDEA projects, plus arbitrary goals can be executed before or after make, run or debug. IntelliJ IDEA also provides coding assistance features for maven pom.xml

• Importing Maven projects to IntelliJ IDEA with automatic artifacts download
• Executing and managing Maven Goals

IntelliJ IDEA 7 introduces the revolutionary approach to analyzing the dependencies between project classes — the Dependency Structure Matrix (DSM).

DSM was designed to help analyzing the structure of complex projects, with thousands of Java classes. DSM reflects the real dependencies between classes in a project, showing them sorted in a way that lets you get the overall picture at a glance, and then perform a deep drill-down in just few clicks.

You can quickly focus on any part of the project, to find cyclic dependencies, unused classes and so on. DSM is integrated with advanced code navigation so and enables you to jump directly to the code which requires your attention. A rich set of code refactorings is provided for resolving the problems.

General DSM view

1. The selection highlights classes which dependencies are being viewed.
2. The ellipsis in cell indicates there are more than 99 dependencies between maven-core and maven-project.
3. The column shows the dependencies of the selected row.
4. The row shows the dependencies on the selected row.
5. Cell indicates that maven-project has 16 dependencies on maven-settings.
6. More dependencies — brighter color.

Automatic cyclic dependency detection

Multiple cross-class dependencies can be analyzed in one view
