Re: [jgrapht-users] Confused with using DOT importer in the latest version

[Dimitrios M. <dim...@gm...>]

This feature is missing in the new importers. It will be back in the next
release. You have
two options:
  - either use the old importer from the 1.4.0 release,
  - use the new importer from the 1.4.1-SNAPSHOT. This is available from
maven, see our webpage on
    how to use snapshot versions.  The new importer has a `VertexProvider`
which you can set and bypass
    the automatic vertex creation. You provide a function which receives
the id from file as an argument and
    creates the new vertex.

We will be releasing 1.4.1 soon.

In any case, see the following link for more details:

Best,
