Compiling the Project

ST-JS compiles with the traditional mvn install command, but it currently needs both Java 6 - that is the default JDK on the command line when you call the Maven command, but also Java 8 to compile the generator-plugin-java8 artifact. To achieve this, you need to to configure the environment variable JAVA8_HOME that points to the home of your JDK 8 home folder.

Something went wrong with that request. Please try again.
