Hi

this post might be somehow related to "Getting Started not working":

in my DSL I have the project wizard which generates this workflow:

module Generator

import org.eclipse.emf.mwe.utils.*

var targetDir = "src-gen-ts"
var modelPath = "src/typesystem"

var projectName = "org.eclipse.xtext.typesystem.generator.tests"
var runtimeProject = "../${projectName}"

Workflow {

bean = StandaloneSetup {
platformUri = "${runtimeProject}/.."
}

component = @workflow.TypeSystemGenerator auto-inject {}
}

in the project org.eclipse.xtext.typesystem.generator.tests and refers
to the workflow in the generator plugin

now, if I run it I get this error:

Caused by: org.eclipse.emf.mwe.core.ConfigurationException: The
platformUri location '../org.eclipse.xtext.example.otherproj/..' does
not exist
at
org.eclipse.emf.mwe.utils.StandaloneSetup.setPlatformUri(Sta ndaloneSetup.java:63)
... 33 more

which complains about not finding org.eclipse.xtext.example.otherproj
(which is another project in my workspace)... but why is this workflow
trying to access that project?

In the workflow I never refer to that project!

thanks in advance
Lorenzo

Hi tracked down the problem a little bit more: the project where I run
the workflow, org.eclipse.xtext.typesystem.generator.tests, has a plugin
dependency on org.eclipse.xtext.example.otherproj; but why does the
workflow try to refer to org.eclipse.xtext.example.otherproj?

thanks
Lorenzo

Hi Lorenzo,

how does the referenced workflow @workflow.TypeSystemGenerator look like?

Btw: Do you think it's a good idea to use the org.eclipse.xtext
namespace for your typesystem?

Regards,
Sebastian

here it is (it's basically the one generated by xtext wizard, with some
modifications):

module workflow.TypeSystemGenerator

import org.eclipse.emf.mwe.utils.*

var targetDir = "src-gen-ts"
var fileEncoding = "UTF-8"
var modelPath = "src/typesystem"

Workflow {

component = DirectoryCleaner {
directory = targetDir
}

component = org.eclipse.xtext.mwe.Reader {
// lookup all resources on the classpath
// useJavaClassPath = true

// or define search scope explicitly
path = modelPath

// this class will be generated by the xtext generator
register = org.eclipse.xtext.typesystem.TypeSystemStandaloneSetup {}
load = {
slot = "rules"
type = "Rule"
}
load = {
slot = "typesystemdefinition"
type = "TypeSystemDefinition"
}
}

component = org.eclipse.xpand2.Generator {
expand = "templates::Start::main FOREACH typesystemdefinition"
outlet = {
path = targetDir
postprocessor = org.eclipse.xpand2.output.JavaBeautifier { }
}
fileEncoding = fileEncoding
}

}

well I don't know... do you think it's better I change it by removing
org.eclipse.xtext?

thanks
Lorenzo
