Here, because CentOS was destroyed by my farm two days ago (the system updates the pot), so all the development environment has to do again.
In fact, before going to Eclipse's official website download is very slow, open official website is also very slow, then you will find down the installation program (only more than 40 MB), the installation process also need to constantly download components from the Internet, this is a very pit dad process.
Not only slow, but also may go wrong halfway, it is not tolerated.
Baidu Long to find a mirror station, http://mirrors.ustc.edu.cn/eclipse/technology/epp/downloads/release/neon/R/, there are a variety of Eclipse installation package, Download it and unzip it and you can use it.
