I have two grammars in the same Project.

the second one is referencing the first one like so:

grammar de.bmw.rhmi.Hmi
with de.bmw.rhmi.App
hidden(WS, ML_COMMENT, SL_COMMENT)

however when I run gradle installDist, I get the error:

Couldn't resolve reference to Grammar 'de.bmw.rhmi.App'.

can you try something like

language = StandardLanguage {
name = "org.xtext.example.mydsl5.MyDsl"
fileExtensions = "mydsl5"

serializer = {
generateStub = false
}
validator = {
// composedCheck = "org.eclipse.xtext.validation.NamesAreUniqueValidator"
}
}
language = StandardLanguage {
referencedResource="platform:/resource/org.xtext.example.mydsl5/src/org/xtext/example/mydsl5/MyDsl.xtext"
name = "org.xtext.example.mydsl5.MyDsl2"
fileExtensions = "mydsl52"

serializer = {
generateStub = false
}
validator = {
// composedCheck = "org.eclipse.xtext.validation.NamesAreUniqueValidator"
}
}

hey thanks that actually worked!!
I am not getting the dependency error anymore, but now I am getting another error when generating the XText Language.

here is my current workflow:

module de.bmw.rhmi.GenerateHmi

import org.eclipse.xtext.xtext.generator.*
import org.eclipse.xtext.xtext.generator.model.project.*

var rootPath = ".."

Workflow {

component = XtextGenerator {
configuration = {
project = StandardProjectConfig {
baseName = "de.bmw.rhmi"
rootPath = rootPath
runtimeTest = {
enabled = true
}
genericIde = {
enabled = true
}
mavenLayout = true
}
code = {
encoding = "UTF-8"
lineDelimiter = "\n"
fileHeader = "/*\n * generated by Xtext \${version}\n */"
}
}
language = StandardLanguage {
name = "de.bmw.rhmi.App"
fileExtensions = "app"

serializer = {
generateStub = false
}
validator = {
// composedCheck = "org.eclipse.xtext.validation.NamesAreUniqueValidator"
}
}
language = StandardLanguage {
referencedResource = "platform:/resource/de.bmw.rhmi/src/main/java/de/bmw/rhmi/App.xtext"
name = "de.bmw.rhmi.Hmi"
fileExtensions = "hmi"

serializer = {
generateStub = false
}
validator = {
// composedCheck = "org.eclipse.xtext.validation.NamesAreUniqueValidator"
}
}
}
}
