Reactivestream library not found

Hello, I’m currently doing this tutorial: GridFS

but the import of the PublisherHelper.toPublisher always fails. Has someone an idea how to solve this? or had to tackle this issue? or knows a workaround ? I don’t want to use the deprecated features from previous versions?
Or does anybody know how to get a ByteBuffer to a Publisher ?

Kind regards,

Hi @lukas_heppel,

The quick starts all use special helpers see: subscribers used in the quickstart. These are basic helpers intended to either create or consume a publisher. They are very basic and would be replaced with a real publisher (in this case a publisher of bytes representing a file).

For more information:

I hope that helps,
