Hi,

I am currently new to Xtext and LSP and tried to create a .jar from the sample project to create a language server to use in a VSCode extension. Unfortunately, when I run Maven install on the parent to create the .jar of the language server, the following errors appear:

/org.xtext.example.mydsl.tests/xtend-gen/org/xtext/example/mydsl/tests/MyDslParsingTest.java:[15,29] package org.junit.jupiter.api does not exist

[ERROR]   location: class org.xtext.example.mydsl.tests.MyDslParsingTest


The build error is only in the tests:
[INFO] Reactor Summary for org.xtext.example.mydsl.parent 1.0.0-SNAPSHOT:
[INFO] 
[INFO] org.xtext.example.mydsl.parent ..................... SUCCESS [  0.273 s]
[INFO] org.xtext.example.mydsl ............................ SUCCESS [ 11.450 s]
[INFO] org.xtext.example.mydsl.ide ........................ SUCCESS [  3.172 s]
[INFO] org.xtext.example.mydsl.tests ...................... FAILURE [  0.302 s]


Here is what I did:
1. Create new Xtext Project (Java 11, Maven, Fat Jar)
2. Generate Xtext artifacts from MyDsl.xtext
3. mydsl.parent -> Run As "Maven install"

Eclipse: Version: 2022-03 (4.23.0)
Xtext: Version: 2.26.0.v20220228-0901
Java: 11.0.14

I'm not that familiar with the tools, so can somebody help me with this? Thank you very much in advance!

did you select or deselect eclipse in the wizard?
if you did not deselct how does your mydsl.target file look like?
does it work if you run maven with a dedicated repo? (-Dmaven.repo.local=somepath)
if not can you provide your project or reproducer as github repo orr similar

so i assume you have some broken files floating around in your local maven repo.

Thank you for your response!

Ok, so with
mvn clean install -Dmaven.repo.local=.m2
it works but it with "Maven Install" from eclipse I get the error even when I delete the .m2 repository before.

the questions would be. which maven repo does "from" eclipse use.
you can specify the -Dmaven.repo.local there too in the vm args line.
i assume the one in your user home.
and how does the jar containg the missing classes
$HOME /.m2/repository/org/junit/jupiter/junit-jupiter-api/5.8.1/junit-jupiter-api-5.8.1.jar look like.
is it a real jar? with proper content?
the next question would be: which java version does it use and which maven version
