Documentation is old

[d-schmidt]

I'm struggeling to find any current docs.

http://www.querydsl.com/ and https://twitter.com/querydsl are stuck in 2016 version 4.1.3
The wiki on Github is almost empty.
I can't even find a changelog. What happened in 4.2.2 and 4.3.1?

I want to know how to tell QueryDSL to generate JDK8 Instants and not old Timestamps from DB.

QueryDSL SQL was never updated for Java 8. In fact, project was not updated for years and only recently started to get picked up again. I am one of the active contributors now, but most of my work revolves around Querydsl JPA as frankly, I am not using any of the other modules.

QueryDSL JPA supports the Java 8 date/times just fine. Which Querydsl module are you using?

[d-schmidt]

Yes, this particular project uses querydsl-sql.

Still, did anybody update any docs or change logs?

[jwgmeligmeyling]

We did update the documentation, but we only recently got access to the website hosting, so we still have to reupload it.

As far as QueryDSL SQL goes, the documentation for 4.1.3 is still accurate though.

@jwgmeligmeyling Would there be a benefit to updating QueryDSL SQL to Java 8? Or do you think focus should be on QueryDSL JPA?

[jwgmeligmeyling]

@MatthewBerk QueryDSL 5.x will require Java 8 minimally, and also support Java 9+. This includes querydsl-sql. The benefits for querydsl-sql will be that we finally support the Java 8 date/time API, and that joda-time will be completely optional. Java 8 also allows for a couple of performance improvements and generally simpler code, also opening the doors to gradually remove Guava as a runtime dependency (which likely wont happen in 5.x yet). There are definitely benefits in Java 8 for querydsl-sql, its just that no changes turned out to be required for querydsl-jpa because the ORM vendor does the heavy lifting regarding Java 8 support.

I am pretty far with my changes:

• Target Java 8 for compilation #2672 (Java 8)
• [#2479] Migrate off of JSR305 #2674 and issue 2460: use Generated annotation with CLASS retention #2677 (Java 9+ support)
• Replace Guava API's with Java 8 ones #2676 (replacing Guava)
