Tutorials fails because of lack of java.xml.bind #474

Open introom opened 3 years ago

introom commented 3 years ago

The tutorial fails because verschlimmbesserung depends on java.xml.bind, however later java verions has ditched it.

We may either update verschlimmbesserung or update the project.clj with java.xml.bind, e.g., https://github.com/jepsen-io/jepsen/pull/244

That's a great idea--want to make a PR against verschlimmbesserung?

Looked into it a little bit, it's not about verschlimmbesserung.

I bumped the version of jepsen from 0.1.13 (as in the tutorial) to 0.2.0, the problem disappears.

For jepsen 0.1.13, it fails because it depends on http-kit, which requires j.x.b, cf. https://github.com/http-kit/http-kit/issues/356

In jepsen 0.2.0, while it still depends on http kit 2.3.0, somehow the problem disappears. Maybe some other dependency has pulled in the j.x.b.

I've created pr to bump the jepsen version in the tutorial. https://github.com/jepsen-io/jepsen/pull/475
