In order to facilitate later work, today in ADT installed Pydev (http://pydev.org/updates), but after the installation, the new project was not found in pydev,perference.
Immediately after trying to install a slightly lower version still does not work, meditation began to think about what was done to make Pydev unavailable.
Finally I found out that the original requirements for the project, the JDK must be under the 1.7 version.
Think of this reason speed installation JDK1.7, of course, environment variables also need to change the previous old version to 1.7, immediately close in open eclipse, haha, can be used.
There are not reassuring friends, you can see again eclipse->windows->perference, is not Pydev has come out.
Find the reason for the Internet, because from pydev3.0 above version, all need JDK1.7 support.
If you do not bother to change the JDK version of the classmate, you can download Pydev3.0 the following version.
I hope to be able to help the friends who meet this problem.
Finished installing Pydev but unable to create Python project
