A lot of Grails internals have been re-written. This is a great thing for the framework itself, but it also surfaces a lot of concerns for the &#8220;Grails Users&#8221;. Some of them are:<\/p>\n<ul>\n<li>How will I be able to migrate my existing Grails app?<\/li>\n<li>Does it bring any changes to how we use Grails?<\/li>\n<li>What happens to the existing plugins and how will they be migrated to 3.x version?<\/li>\n<\/ul>\n<p>A lot of these concerns are well founded as the core team has mentioned on numerous occasions that they are not holding themselves back by backward compatibility. That in itself is a big decision but we have to say that it is a correct one as well if Grails has to maintain its glory.<\/p>\n<p>When it comes to Grails, one of it&#8217;s biggest strength is it&#8217;s plugin repository. However, with 3.x, most of the plugins have become unusable(remember no backward compatibility). This is where we, the Grails community need to play a solid role and contribute. We at TTN Digital (erstwhile Intelligrape) are taking this responsibility very seriously and trying to pay back to the great framework and the community behind it.<\/p>\n<p>We started working on migration of existing Grails plugins to the latest version(Grails 3). So far we&#8217;ve migrated 3 plugins:<\/p>\n<ul>\n<li><a href=\"https:\/\/github.com\/kefirfromperm\/grails-asynchronous-mail\" target=\"_blank\">grails-asynchronous-mail<\/a><\/li>\n<li><a href=\"https:\/\/github.com\/gpc\/grails-export\" target=\"_blank\">grails-export<\/a><\/li>\n<li><a href=\"https:\/\/github.com\/puneetbehl\/grails-clojure\" target=\"_blank\">grails-clojure<\/a><\/li>\n<\/ul>\n<p>Also, I would like to commend that docs are very helpful. It&#8217;s very easy to migrate existing plugins by following <a href=\"http:\/\/grails.github.io\/grails-doc\/latest\/guide\/upgrading.html#upgradingPlugins\" target=\"_blank\">Grails Docs: Upgrading Plugins<\/a><\/p>\n<p>We are currently working on few more plugins and will keep sharing our experience.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Now that Grails 3, the most anticipated release of Grails is out, which comes with lot of new features like: Gradle Build System.
