Upgrading Xtext/Xtend Versions [message #1863505]

I've updated all the Eclipse/Xtext/Xtend dependencies.

The ant build first generates xtext artifacts. I've successfully edited the mwe2 workflow to create xtext generated class files.

The next compile-xtend part of the build gives me errors in an xtend file. Could there be a new xtend syntax I'm unware of that for some reason xtend.core is not seeing the interface created by xtext?

Can you give more details,
This looks like a java version problem
Or wrong asm version problem

Thanks for the quick reply.

java -version
openjdk version "11.0.14.1" 2022-02-08 LTS
OpenJDK Runtime Environment 18.9 (build 11.0.14.1+1-LTS)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.14.1+1-LTS, mixed mode, sharing)

ant -version
Apache Ant version 1.8.0 compiled on February 1 2010

I've also included a file with all the dependencies buckminster initially copies to a /tmp directory and ant adds to its Java classpath.

In the .xtend file that is giving compile errors, the errors have to do with interfaces generated by xtext mwe2 workflow.
For example: [java] 1046: The method getName is undefined for the type Object. The xtext generated 'public interface Feature extends EObject' contains a method 'String getName();' At xtend compile, "feature.getName" is seen as a generic Java Object

Please let me know if you could use more information.

the interesting question would be how you configure the ant task.
and which of the dependencies you use / if you have regex filters etc.
e.g. as we have here
https://github.com/eclipse/xtext/blob/9ee860cce6ea001ee12f8b8c71bb433fdc5b762b/org.eclipse.xtend.ide.tests/batch-compiler-data/ant/test.ant

Below is how the compile-xtend is configured in build.xml :


<target name="generate-xtext-artifacts">
<java classpathref="classpath"
classname="org.eclipse.emf.mwe2.launch.runtime.Mwe2Launcher"
fork="true">
<arg value="${workflow}"/>
</java>
</target>


<target name="compile-xtend">
<pathconvert pathsep="${path.separator}"
property="classpath-string"
refid="classpath">
</pathconvert>
<java classpathref="classpath"
classname="org.eclipse.xtend.core.compiler.batch.Main"
fork="true"
failonerror="yes">
<arg value="-cp" />
<arg value="${classpath-string}" />
<arg value="-d" />
<arg value="${basedir}/xtend-gen" />
<arg value="${basedir}/src-gen${path.separator}${basedir}/src" />
<arg value="-encoding" />
<arg value="UTF-8" />
</java>
</target>


<target name="compile-java">
<mkdir dir="bin"/>
<javac classpathref="classpath"
destdir="bin"
source="11"
target="11"
includeantruntime="true">
<src path="src" />
<src path="src-gen" />
<src path="xtend-gen" />
</javac>
<copy todir="bin">
<fileset dir="src" excludes="**/*.java,**/*.xtend" />
<fileset dir="src-gen" excludes="**/*.java,**/*.xtend" />
<fileset dir="xtend-gen" excludes="**/*.java,**/*.xtend" />
</copy>
</target>

what is
classpath-string

i also wonder if you should pass 11 as javaSourceVersion to the xtend compiler.

besides that a reproducibe project would be helpful

I'm not sure what that is used for. It was used 10 years ago in this xtext ant build:

https://xtextcasts.org/episodes/12-building-with-ant?autoplay=true

My build seems to be based off that, and updating to Java 11 with new xtext/xtend seems to have broke that build structure.

Yes.
And it still does work.
But I need to debug and don't have the time to create a reproducer

and a trivial example works for me

I trying to put something reproducible together that I can share. Another option I am considering trying is removing xtend all together and using the generated java code. Have you seen any projects that have done that in the past?

yes i have.

boils mainly down which xtend features you are making heavy use of

Your early reports suggest a problem with 'Object'. In my experience this usually indicates a crazy configuration or just failure to rebuild adequately. The latter can be fixed by a few refresh-all / rebuild-all / restart cycles. Try a simple Xtext tutorial example to see if your installation is viable.

I only have one .xtend file used in as a generator when producing xtext artifacts. So maybe it wouldn't be too difficult to remove xtend from the build.

In the mwe2 file attached, xtend files are being generated and the java files I have for scoping and validation seem to be ignored.

With the attached workflow, do you see something I might be doing wrong?

I would to use existing scoping, validation, formatting java files in the xtext workflow instead of the generated xtend files.
