Build a language server for DSL [message #1818355]

Eclipse User

Hi, I want to build a language server for DSL in eclipse. I was following the tutorial on (www.typefox.io/blog/tutorial-building-a-language-server-for-your-dsl). After setting the configuration of the xtext project, errors occur as in the picture attached. I could not solve these errors and Run "Generate xtext artifacts".

please make sure that you have a java 8 in your ide or select java 11 in the wizard.
also make sure that gradle can download all dependencies and is not blocked by a firewall or something like that
you might also use the latest xtext version and not the quite old one you are using right now

you might also digg why gradle fails and if the gradle consoles or the error log tells anything about that

I am using Java 8 and java 11 in the wizard is selected.
The Xtext version is latest, "Eclipse Xtext 2.20.0".
Gradle seems download all dependencies.
But, the error remains.

When I try to build, the console shows:

Working Directory: C:\Users\hanzwang\eclipse-workspace\org.xtext.example.mydsl.parent
Gradle user home: C:\Users\hanzwang\.gradle
Gradle Distribution: Gradle wrapper from target build
Gradle Version: 5.6.3
Java Home: C:\Program Files\Java\jdk-13.0.1
JVM Arguments: None
Program Arguments: None
Build Scans Enabled: false

Gradle Tasks: <run default tasks>

FAILURE: Build failed with an exception.

* Where:
Initialization script 'C:\Users\hanzwang\eclipse-workspace\.metadata\.plugins\org.eclipse.buildship.core\init.d\eclipsePlugin.gradle'

* What went wrong:
Could not compile initialization script 'C:\Users\hanzwang\eclipse-workspace\.metadata\.plugins\org.eclipse.buildship.core\init.d\eclipsePlugin.gradle'.

please make sure you use consistent java home versions and selection of java version in new project wizard.
gradle 5.6.x has no support for java 13 nor has xtext. please use java 11 or java 8
