GitHub import Maven project to eclipse

For Java projects, most of what you see on GitHub is built on Maven, and many are now switching to gradle, such as Hibernate and spring. Recently want to study some open source projects, but after the clone import eclipse, found that the source package is a normal file display, so that the class can not jump directly between the source code to look very laborious, as shown in the following figure:

The reason for this is that the GitHub Maven project typically does not place local profiles into a version library for structure clarity and does not rely on specific Ides. This way, when you import eclipse, you cannot be identified as a regular project because you do not have a. Classpath,.project, the solution is as follows:

Method one, using MAVEN to build Eclipse projects

MVN Eclipse:eclipse

It is convenient to use the above command to import the generated artifacts into eclipse.

Method Two, add and modify. classpath and. Project files

In the beginning I used this way, later found too cumbersome to give up use, you can refer to from the GitHub Maven project to import Eclipse4.2.
