Languages under plugin are not getting deployed to MPS

I have built and added some new plugins to MPS and when I am trying to use them I am getting the following error "The language is not deployed 'com.abc.plugin.implementation'"

Anybody faced the similar problem and have a solution can help me? MPS Version used: 2017.1.2 JDK: 1.8

Solution

  • This issue is a bug in MPS which is logged in youtrack as below: https://youtrack.jetbrains.com/issue/MPS-26437

    Layout node for plugin places all modules of a group under a single folder. If there's a devkit among the modules, only devkits are loaded (https://youtrack.jetbrains.com/issue/MPS-25852), and other modules are ignored.

    Unless we've got devkits deployed as regular modules, not simple files, MPS could place these devkit files separately when deploying a module as a workaround.

    This problem is resolved and available with commit # 2edca430f054c908eb7606bad8ac6af46e0a7352
