Issue
Note: this question is similar to this one, but the answers there did not work for me.
I have an odd problem: using Maven in the command line, my build is succesful, but imported in Eclipse it still shows errors. In particular, I'm trying to build the open-source rosetta-dsl project, which is a multi module Maven project containing Xtext and Xtend files.
Running mvn clean install ends with the following result:

Eclipse shows 40 errors, including:

What I have tried:
- Right-clicking on the project and running Maven > Update Project... (which is the top anwser of the similar post)
- Deleting the project and reimporting it as a Maven project
- Updating Maven, the m2e Eclipse plugin and Eclipse to the latest version
- Running
mvn clean, Project > Clean, closing and reopening the project, ... and rebuilding
but the problem persists, and after fruitlessly searching for a solution for the last three days, I'm not sure how to continue.
I don't know how or why this project behaves differently from the one in the linked question, so here are more details:
> mvn --version
Apache Maven 3.8.1 (05c21c65bdfed0f71a2f2ada8b84da59348c4c5d)
Maven home: C:\Users\Thesis\apache-maven-3.8.1\bin\..
Java version: 11.0.2, vendor: Oracle Corporation, runtime: C:\Program Files\Java\jdk-11.0.2
Default locale: nl_NL, platform encoding: Cp1252
OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"
- JDK compliance in Eclipse is set to 11
- I'm running Eclipse DSL Tools version 2021-06 (4.20.0)
Any idea how to solve this?
Solution
For plugin-development, Eclipse needs to have a target platform configured. You can find a target file in the com.regnosys.rosetta.target project.
If you open that file with the target editor you will find a button in the top right that allows you to set the file as active target platform in your eclipse.
