ANN: Grails 3 Milestone 1 Released

[Graeme Rocher]

Hi all,

We have released Grails 3 Milestone 1 and it can be downloaded from
the new location at:

https://github.com/grails/grails-core/releases/tag/v3.0.0.M1

If you are a plugin author now is the time to consider looking at
porting your plugins to Grails 3.

You can find some example plugins here:

https://github.com/grails3-plugins/

In particular with the code gen and build system based on Gradle some
plugins that interact heavily with the command line will require
updates.

I have posted a video of Grails 3 in action on YouTube:

https://www.youtube.com/watch?v=aro3_RZqgtU

Hopefully this will get you excited to consider updating plugins. For
publishing we recommend publishing your plugin to Bintray. We will be
working on a Bintray based Grails 3 plugin portal soon. The previous
portal will continue for Grails 2 plugins.

We look forward to the plugin community help drive forward Grails 3

Thanks, and look forward to your feedback.

This is excellent news! 

Is there any organized way we can help upgrading plugins? I'm thinking on the current "core" plugins (the ones flagged as supported by Pivotal), like Spring Security Core.

Cheers.

I plan to look at Spring Security Core soon, but a great area to
contribute would be forking and trying to port some of the popular
community developed plugins:

https://grails.org/plugins/?filter=installed

Like 'mail' etc. since they are just JAR files they can be published
to Bintray for the moment

Thanks

Any idea when the Upgrade Guide from 2.x will be finished?

I don't really want to beat my head against things that might end up in there as required changes.

Thanks,

Aaron

Will there be any compatibility mode with previous Gant scripts?

It whould help a lot of people which have customized build processes.

Awesome work guys! Looking forward to kicking the tires around. It appears that the build / run / test speeds are all going to be vastly improved which I am looking forward to.

[Graeme Rocher]

Unfortunately no, but the new API is way more elegant. I hope folks
pick it up and run with it :)

Graeme,

will scaffold work the same way? How will be the upgrade process for people who customized their scaffolding templates?

hi,

nice!

asset-pipeline(-core) just introduced/fixed classpath asset resolution:
https://github.com/bertramdev/asset-pipeline/commit/7b50229aacfa69c9a639bb6281e024aa91d4f5c5
https://github.com/bertramdev/asset-pipeline-core/commit/62c77e0e0b8061aae41ade952153017582ae9dca

to make this work properly, i think for jar-builds (e.g. plugins)
grails-gradle-plugin should put the assets under jar:/META-INF/assets
instead of just jar:/assets.

does this look correct or am i perhaps missing sth?
davydotcom basically confirmed this already:
https://github.com/bertramdev/asset-pipeline/commit/7b50229aacfa69c9a639bb6281e024aa91d4f5c5#comments
grails 2.x ref.:
https://github.com/bertramdev/asset-pipeline/blob/master/scripts/_Events.groovy#L20

thanks, zyro

Hi,

In case others have problem opening a Grails 3 project in IntelliJ, as showed in the screencast:

On the “Import project from Gradle” dialog I got:

Resolve error
Cause: asset/pipeline/gradle/AssetPipelinePlugin : Unsupported major.minor version 51.0

This is due to default project SDK in IntelliJ being set to Java 6 or nothing at all, and the Gradle import dialog has as far as I can see no support for selecting SDK version for a project before importing.

To fix this:
- Close all projects
- Select: Configure —> Project Defaults —> Project Structure
- Set Java 7 or 8 as default Project SDK


Best Regards,
Ronny

[Ronny Løvtangen]

However, I was not able to run Application.main(…) from within IntelliJ. Got the following exception. Any hints? Is there some invokedynamic settings I need to perform?
Tried with JDK 1.7.0_65 and 1.8.0_11.

Try JDK 1.7.0_75 (last & latest of 1.7). Also make sure JDK in classpath is mutually exclusive while toggling between versions 7 & 8.

This is highly likely to happen in OS X.

Thanks

Both 1.7.0_75 and 1.8.0_31 worked fine :)

I can't wait to try it! I'll save some time this week end for this :)

It looks awesome, thanks Graeme !

Looking forward to migrate our plugins.

Do you want us to start reporting bugs?

It looks like, current 'grails package' does not support parent folder name with a dash:

Execution failed for task ':compileGroovyPages'.

> org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:

  /Users/ben/Documents/Projects/grails/test-grails3/build/gsptmp/gsp_test-grails3error_gsp.groovy: 8: unexpected token: - @ line 8, column 15.

     class gsp_test-grails3error_gsp extends GroovyPage {

When renaming the parent project from test-grails3 to test_grails3, it works fine.
