Creating an IntelliJ Platform Plugin Project

To develop applications in IntelliJ IDEA, you need a Java SDK (JDK) . A JDK is a software package that contains libraries, tools for developing and testing Java applications (development tools), and tools for running applications on the Java platform (Java Runtime Environment — JRE).
