It's over a year that we have had a commit for QueryDSL. https://github.com/querydsl/querydsl Shall we consider this project Dead or is it moving to a new group? I guess the old team have no plan to maintain it anymore. New JDKs arrive every 6 months and I guess this project will be out of date sooner than we expect. Any news or compatible alternative?

Querydsl is an extensive Java framework, which allows for the generation of type-safe queries in a syntax similar to SQL. It currently has a wide range of support for various backends through the use of separate modules including JPA, JDO, SQL, Java collections, RDF, Lucene, Hibernate Search, and MongoDB.
Querydsl is a framework that enables the construction of statically typed SQL-like queries through its fluent API. Spring Data modules offer integration with Querydsl through QuerydslPredicateExecutor .
3.1. This tool generates the so called Q-types — classes that directly relate to the entity classes of your application, but are prefixed with letter Q. For instance, if you have a User class marked with the @Entity annotation in your application, then the generated Q-type will reside in a QUser. java source file.
I joined the querydsl team several years ago but lost interest due to the time constraints of having a full time dev job. I am however still a member of their Slack workspace and as of today, no-one has posted in the #general channel since July 2018. When I was active, the channel was busy most, if not every day.
I'm led to believe that Timo Westkämper (owner) is too busy / has lost interest, as with most (all?) other devs excluding Ruben Dijkstra who has contributed a great deal towards the project but is busy with University. He intends to come back. I heard that Atlassian started contributing but there was no-one to up-skill them and deal with their prs, so they ducked out.
In summary, AFAIK, no-one is working on the project and it would appear the owner has lost interest. I'm considering JOOQ but worry it's somewhat of a one-man-band too. If Lukas moves on, we could be in a similar situation.
I think querydsl is a great tool and it's free for all RDBMS, compared with better maintained JOOQ. In my personal opinion, I'd like to see, minimally, querydsl-sql forked by the open source community, its dependencies reduced (it brings in a lot for what it is) and its Java version brought up to date. Perhaps querydsl-jpa could follow. These, IMO, are by far the most used jars and the more specialised functionality could be dropped, E.G.

Timo has approved the handover of the project.
UPDATE
The querydsl team is back in action with querydsl 4.2.2 in Maven central as of 22-Nov-2019 and querydsl 5 in the pipeline. Thank you to the new team members for breathing life into this excellent project.
