JDK version for Groovy
Is it still required to have 1.6 as a base JDK version for new Groovy
releases?
Isn't it time to say if you are still on JDK1.6 then stick with the
Groovy you have?
This could be said for JDK7 of course since it is EOL.

What's a timeline for Gradle 3.0 GA?
Thanks,

Gradle 3.0 is JDK 7+ only. It's also the only one compatible with JDK 9.
Our `master` branch is already using Gradle 3.0, but we didn't make a call
regarding support of JDK 6 for 2.5.

Hard to say, we're growing fast so it could be quicker, but between 1 and 2
years is reasonable.

sure, we would stay with 1.6 source then

Hi Jochen,
javac doesn't allow you to compile a code with -source 1.7 and -target 1.6
you have to use a tool like ASM for that and i think it was rule out by Cedric or Guillaume.
cheers,

actually maybe there has been a misunderstanding.. if we want to use
JDK7 to build but still target JDK6 as target bytecode level I am for it
actually.
The Groovy 3 story would be different though. Here we would produce JDK8
bytecode and use JDK8 source code features

Gradle 3 is the only reason to even make the switch from JDK6 to JDK8. I
imagine if we would not want to use Gradle3 we would still switch to
JDK8 or newer in Groovy 3, but stay with JDK6 otherwise.

What do you think will be the smallest relatively realistic time frame
for the arrival of Gradle 4? About 2 years again?

Re: JDK version for Groovy

Gradle 3.0 will require JDK 7. Gradle 2.x can run on JDK 6. I'm not a big
fan of "backporting". To me it's easier to complete 2.5 with JDK 7 now,
then switch master to 3.0 and upgrade to JDK 8 there. One of the reasons I
would consider this decision touchy is that Gradle would then not be able
to migrate to Gradle 3, at least until Gradle 4.0. But, given the large
number of plugins written in Groovy today, upgrading would be a problem
anyway if Groovy 3 breaks binary compatibility.

Do you know what are the latest requirements for Grails and Gradle? They're
all on JDK 7+?

I really really would like to switch to JDK8 right away for many
reasons... but I think we need a JDK6 support story still. How about 2.5
in JDK8, but with backport to JDK6?

Re: JDK version for Groovy

This sounds reasonable to me too.
For Groovy 3, since we've not yet really decided any time scale, we might
even go with 9 then :-) but we've got time to decide for that one!

I was thinking of this but didn't get to send an email yet. I basically
think we should make Groovy 2.5 JDK 7+ only, and Groovy 3 JDK 8+.
