Download : Integrated Development Environment

As the CDE is provided as an Eclipse P2 repository, it can be installed from the CDE Eclipse update site. The Eclipse plugin and Curl RTE installers can both be acquired from the CDE Eclipse update site, in which case the Curl installer will be launched via the CDE plugin. For the URL of CDE Eclipse update site, please contact our support center

Before installing the CDE, please install Eclipse. A matching JVM version must also be installed. Su / Oracle JDK 1.8+ is recommended）.

Users using old versions of Eclipse might meet signature verification error, see here for a workaround.
