GrammarCells not found by Standalone IDE build script

Question

What’s the right way to add a third-party dependency to the build file?

I’m trying to build a standalone IDE for a language that uses grammarcells as dependency, but I get an error saying that the dependency cannot be found during the build process.

cannot find used language in dependencies: com.mbeddr.mpsutil.grammarcells

The error only occurs for the Build Solution, in the language solution, I can use grammarcells without issues.

Grammarcells is loaded into my IDE

It is also in my Solution for the Standalone IDE

And model

However I get the same error every time I try to build the project

Any idea how to solve this problem?

Answer 1

To solve the problem, I did the following two steps:

First, I added de.itemis.mps.grammarcells.build to your build model.

Second, I added de.itemis.mps.extensions to the list of dependencies in my build script

Finally, Re-Build :)

Thanks to @arimer from the MPS slack channel for helping me to solve the problem.
