Submissions are not found (language not supported)

I have the following folder structure

assignments
    student1
        src
            codegrouping
                file1.ts
                file2.ts
    student2
        ...

When running java -jar jplag.jar ./assignments I get the following response:

What am I doing wrong here? Do I need to specify the subdirecotry somehow? -s didn't help unfortunetely

It looks like you are trying to parse Typescript files. Sadly, we do not support typescript yet. However, we would be interested in that. See here for how to add new languages: https://github.com/jplag/JPlag/wiki/4.-Adding-New-Languages

When running JPlag the default language is Java, other languages can be selected via the -l argument. If your files would have been e.g. C# files an appropriate call would have been: java -jar jplag.jar -l csharp -s src ./assignments

Update 2024: Now, we support javascript and typescript.

What if the submission is a maven project containing multiple modules? I got [ERROR] CLI - Submission student1 does not contain the given subdirectory 'src' when I use -s src. I tried -s */src but zsh: no matches found: */src/

assignments
    student1
        module1
            src
        module2
            src
        module3
            src
    student2
        ...

student1 does contain src; it only contains the module folder, right? So Either drop -s or try -s module1/src.
If you want to check all modules, you do not need -s.
