Problems with AbstractFormatter2 when building with gradle [message #1754437] Fri, 17 February 2017 14:55 Go to next message
Eclipse UserFriend
I have a DSL for a language in this multi-project:
https://github.com/JPL-IMCE/jpl.imce.oml.specification.parent

It builds fine with gradle, including an Xcore metamodel
and an Xtext grammar with a few additional Xtend code generators.

I tried to add a formatter following the doc for the new AbstractFormatter2 API. When I build in the Eclipse IDE; it works fine -- i.e., I can launch
a runtime eclipse and test the formatter.

However, when I build with gradle, I get errors like this:

:jpl.imce.oml.specification:generateXtext FAILED

FAILURE: Build failed with an exception.


It seems that there is some kind of registration or injector missing when running in standalone with gradle that happens when running in the IDE.

I'm using Eclipse Neon with Xtext 2.10 and the xtext-gradle-plugin 1.0.17

Any suggestions?

To give you a sense of what's going on, here's an example of a formatter that builds OK with gradle as long as it doesn't use the injected grammar access:


@SuppressWarnings("all")
class OntologicalModelingLanguageFormatter extends AbstractFormatter2 {
	
	@Inject extension OntologicalModelingLanguageGrammarAccess

	def dispatch void format(TerminologyExtent terminologyExtent, extension IFormattableDocument document) {
		terminologyExtent.prepend[noSpace]
		
		for (AnnotationProperty annotationProperty : terminologyExtent.getAnnotationProperties()) {
			annotationProperty.format;
		}
		
		for (TerminologyGraph terminologyGraph : terminologyExtent.getTerminologyGraphs()) {
			terminologyGraph.format;
		}
		
		for (Bundle bundle : terminologyExtent.getBundles()) {
			bundle.format;
		}
		
		for (DescriptionBox description : terminologyExtent.getDescriptions()) {
			description.format;
		}
	}

	def dispatch void format(AnnotationProperty annotationProperty, extension IFormattableDocument document) {
		annotationProperty.prepend[noSpace]
		//annotationProperty.regionFor.ruleCall(annotationPropertyAccess.ANNOTATION_PROPERTY_TOKENTerminalRuleCall_0).append[oneSpace]
		//annotationProperty.regionFor.ruleCall(annotationPropertyAccess.EQUALTerminalRuleCall_2).surround[noSpace]
		annotationProperty.regionFor.feature(OMLPackage.eINSTANCE.annotationProperty_Iri).append[newLine]
	}


When I build, I get:

I guess one workaround is to engineer the formatter2 without actually using the grammar access.

For example:

//annotationProperty.regionFor.ruleCall(annotationPropertyAccess.ANNOTATION_PROPERTY_TOKENTerminalRuleCall_0).append[oneSpace]
annotationProperty.regionFor.keyword("annotationProperty").append[oneSpace]
		
//annotationProperty.regionFor.ruleCall(annotationPropertyAccess.EQUALTerminalRuleCall_2).surround[noSpace]
annotationProperty.regionFor.keyword("=").surround[noSpace]


It would be nice if we could use formatter2 with grammar access and have that build properly with the xtext-gradle-plugin.

Has someone tried this combo?

sounds like https://github.com/eclipse/xtext-extras/issues/30 which is fixed in the current xtext 2.11

Indeed, this looks like the same bug.

I'll try to upgrade to Xtext 2.11.

Argh... the Neon modeling package includes EMF Parsley 1.0.2 which in turns requires Xtext 2.10 currently.
I guess I have to wait before I can use Xtext 2.11.

Doing formatting without grammar access is not very pretty; I couldn't get any of the indentation to work as it used to.
So I created a branch with an eclipse target configured for Xtext 2.11; hoping to be able to use grammar access for formatting with indentation.
I had to add a few explicit dependencies compared to what I had for Xtext 2.10.

https://github.com/JPL-IMCE/jpl.imce.oml.specification.parent/tree/xtext2.11

The problem I'm encountering now is in generating the tests from Xtend.
Every test X defined in X.xtend, I get an error that X is already defined in X.xtend.
Why is this an error? I cleaned the project but I still get these errors.

maybe eclipse and gradle come it other in the way. sounds similar to https://github.com/xtext/xtext-gradle-plugin/issues/72
unfortunately your setup seems to be highly customized. thus having a smaller reproducible example would be nice.

Following your suggestion, I made a simplified example with just the Xcore metamodel, the Xtext grammar and some unit tests.
See this branch: https://github.com/JPL-IMCE/jpl.imce.oml.specification.parent/tree/xtext2.11.basic

I removed all generated files including Eclipse metadata.
To build, start:

./scripts/travis-build.sh

This should succeed; however, it is lacking generating the ecore metamodel from the Xcore source.
I haven't figured out how to do this from gradle.

besides this java.srcDirs = ['src', 'build/src-gen']

but you generate to src-gen. => stuff does not get found

so i am wondering why you did not take the gradle stuff generated by the wizard as start

Building Eclipse plugins/features & publishing has been a problem for many years for me because I really don't grok Maven pom.

I am accustomed to working with Scala & SBT; which is really nice because there is a lot of compile-time checking that helps understand what's going on.
Gradle is somewhat similar to SBT in the way it operates except that it lacks the compile time checking and adds a lot of dependency injection.
I find this a lot more difficult to understand.

Regarding the gradle wizard: yes, I had tried the wizard; however, I also needed to publish a P2 repo built from features & plugins.
All the examples I searched for were using tycho/pom. The closest I found was Eclipse Buildship itself -- it's bizarre that the project
isn't going to publish reusable scripts. So I copied & adapted their scripts -- Not very easy to do because there is really poor support for editing these kinds of scripts in Eclipse.

Now, I managed to simplify even more my project here:
https://github.com/JPL-IMCE/oml.core

I kept the essential -- i.e., all the Xcore, Xtend, Xtext stuff.
The problem now is that in order to use the Xtext 2.11-based grammar access formatter; I need to build the enchilada using gradle.
And that's where the problems begin.

It seems that I'm missing something that would "compile" the source Xcore file to generate several artifacts; including an ecore file.
I'm surprised that the ecore file is needed because it's not even generated in the itemis example here:
https://github.com/itemis/itemis-blog/tree/xcore_gradle

I kept my example as close as that one except that I use Xtext 2.11 and that I use EMF/CDO.

and i dont get your point:

the xcore file a a ecore+genmodel i n one.
using xtext-gradle-plugin should work fine generating code (the strange warnings you can get rid of with bundleManifest="false" to the @GenModel - you have to maintian plugin.xml and manifest manually.

Thanks for the tip; I updated the genmodel annotations following the itemis-blog example for xcore-gradle-build and added repository & dependencies for cdo.

Now, I can build; however, there are strange errors that do not break the build (see the abbreviated stack traces below)
Is this normal?

sounds like a question for the emf forum. (its pure xcore specific)

I carefully compared my project with https://github.com/itemis/itemis-blog/tree/xcore_gradle
Even simplified mine to be as close as possible to the itemis example.

Ultimately, I found that there is a difference in the *.xcore source that causes a difference in the beheavior of the gradle generateXtext task.

In the itemis example, the xcore is simple and the generated source impl folder does *NOT* have an *.ecore file.

In my case, the xcore is more complicated and when building with the Eclipse IDE, the generated source impl folder contains an *.ecore file.
The problem is that, currently, the xtext gradle builder does not have a way to specify some kind of EMF ResourceSet Pathmap so that it could properly save the generated *.ecore file -- when it has created one.

As far as why the Xcore builder generates an *.ecore file in some complex cases but not in simple ones; I haven't figured out exactly why.
I made some tests by commenting/uncommenting some sections; re-running the gradle generateXtext task to see if it produces errors or not.
It is unclear what really causes this difference in behavior.

It's worth asking on the EMF forum about the Xcore generator specifically.
If it is necessary for the XcoreGenerator to produce an *.ecore file for my metamodel; then the problem remains that there seems to be something missing w.r.t. being able to specify some kind of EMF ResourceSet pathmap in gradle.

It would be nice to have a possibility to specify the path maps in gradle and maybe the xtext maven plugin
I am not sure where to address this issue

- at emf (where xcore resides)
- at xtext-gradle-plugin
