Visualize package dependencies with mermaid and 'bnd xref'

TIPS
1
  1. Run the bnd xref command in your comand line (e.g. install via brew on MacOS):

bnd xref */generated/*.jar | sed -r 's/ < / --> /g'

The sed replaces the < in the output with -->. The direction might not be correct, but I just wanted to get something working.

  1. Paste the output or parts of the output to https://mermaid.live/

  2. Get a visual graph or something like this:

Feel free to modify it as needed with filtering and what not. Inspired by this github issue.

The bndlib contains a DOT class that makes it trivial to turn this into a dot file. (graphviz).

Note that the bnd resolve command has such an option

Thanks @pkriens . Any hints about the bnd resolve command?
I tried:

cd myworkspace_with_a_cnf_folder
bnd resolve dot my.bundle.with.the.bndruns/myapp.bndrun

But I got “Resolution failed Unable to resolve” … although when I click resolve in Eclipse on the myapp.bndrun, it resolves.

Am I in the wrong folder?

You have to be in the project directory. I guess the resolve command has a -p to direct this to another directory.

bnd resolve dot test.bndrun
