Error registering query when trying Getting Started about mantis

[aspcompiler]

If I repeat running the query, I got a better error message of "class not found" on io.mantisrx.sourcejob.synthetic.core.MQL:

Hey aspcompiler! Sorry for the delay in getting to this, I am able to reproduce your issue and will work on getting a fix out this morning.

[codyrioux]

A quick update @aspcompiler it looks as though a string replace botched the MQL wrapper. You should be good to go with the latest commit, feel free to play with the query a little bit, source jobs implement the projection and filtering semantics of MQL but rely on the client to do some of the more advanced functionality. We have an mql-lite job somewhere that does this, I'll see about getting it added to the repository this morning.

Thanks for trying us out, and sorry about this error!

[codyrioux]

Oh, and there is an mql-lite in the mantis-examples mql-lite branch. I'll get this merged early next week.
