How to check within a plugin mandatory plugins

Elastic Stack Elasticsearch
1

Heya,

I would like to check if mandatory plugins for my own plugin are loaded.
Is it possible?

For example, I have the FSRiver which depends on mapper-attachment plugin.
I'm thinking of verifying mapper attachment plugin when the river starts:
https://github.com/dadoonet/fsriver/blob/master/src/main/java/org/elasticsearch/river/fs/FsRiver.java#L83
https://github.com/dadoonet/fsriver/blob/master/src/main/java/org/elasticsearch/river/fs/FsRiver.java#L83

Is it the best place to do it or is it better to do it when I register the
plugin:
https://github.com/dadoonet/fsriver/blob/master/src/main/java/org/elasticsearch/plugin/river/fs/FsRiverPlugin.java#L45
https://github.com/dadoonet/fsriver/blob/master/src/main/java/org/elasticsearch/plugin/river/fs/FsRiverPlugin.java#L45

And how can I check that in Java?

Thanks for your advices.
David.

If you get access to the node during river startup, you could do it via
guice injector access I guess

MyClass instanceOfClazz = ((InternalNode)
node).injector().getInstance(MyClass.class);
