asset-pipeline | Laravel 4 package | Runtime Evironment library

I'm using a Grails project and I updated my gradle-wrapper from "gradle-2.9-all" to "gradle-3.0-bin" and I get this error:

An exception occurred applying plugin request [id: 'io.spring.dependency-management', version:` '0.5.2.RELEASE'] Failed to apply plugin [id 'io.spring.dependency-management'] Could not create task of type 'DependencyManagementReportTask'.

My build.gradle:

I have Grails 3.3.11 application, and I'm trying to deploy it on flexible Google App Engine, however, I have some errors mainly produced from connecting to Google cloud SQL, I made MySQL 5.7 instance on it and able to access it from my IDE and while I run the application locally,I searched for some solutions for theses errors but unfortunately, nothing worked for me, here are the exceptions

When I try to create a functional test using:

grails create-functional-test acceptance.tests.Logout

I'm getting this error, because Spock tries to use a wrong Groovy version:

But in my project only Groovy 3 is a library.

Here is my build.gradle:

I placed an image 'jumbotron.jpeg' in the app/assets/images folder, which I use in a view:

I'm trying to run my grails 4 application and I'm constantly getting this stacktrace:

I did my research but I didn't find any working solution

I have a site_settings.scss file which contain all the the variables for my Rails app:

I'm trying to use ES6 syntax in my Javascript files, in a Rails project. I also need to minify the Javascript files (mine, and the ones included by libraries like rails-ujs) for performance reasons.

When I first generated the project and ran it locally, it worked fine. However, this is because the environment configurations are different for development vs. production. In the development configuration, there is no minification. In the production configuration, Uglifier is used to minify Javascript.

Once I tried to deploy to production, Uglifier and ExecJS started throwing up all kinds of syntax errors, such as not recognizing the const keyword or not recognizing the > in the => operator of arrow functions.

After spending a few hours searching for a fix, I resorted to simply disabling Uglifier so that I could deploy successfully. However, now that my site is in production and working, I would like to make this optimization work.

I'm familiar with Babel and Webpack, and I've used them in other projects (along with some custom scripts) to generate browser-ready ES5 code (for Internet Explorer) and browser-ready ES6 code (for every other browser). If I wasn't using Rails, this would be trivial for me to solve.

However, since I'm using Rails, I need to figure out how to do this in the context of the Rails Asset Pipeline. Surprisingly, there doesn't seem to be any standard way to do this, despite ES6 being 4 years old and supported by every modern browser. It's really weird that Microsoft Edge is way ahead of Rails on this one.

Here's a few suggestions that I've seen, and the problems with them.

• https://github.com/babel/ruby-babel-transpiler

  • Has no documentation indicating how it should be used in the Rails Asset Pipeline.

• https://www.rubydoc.info/gems/uglifier

  • Included by default in Rails, but doesn't support ES6 syntax.
  • Mentions "experimental ES6 syntax support", but it doesn't work, even when you enable "Harmony mode".
  • It uses the word "experimental", and I'm trying to use this in a production app. Any serious Javascript tool should have stable support for ES6 by now.

• https://github.com/fnando/babel-schmooze-sprockets

  • Unclear documentation, includes a lot of caveats about having to do weird nonstandard things like call .default() on all of your imports.

• https://nandovieira.com/using-es2015-with-asset-pipeline-on-ruby-on-rails

  • Mentions having to use a "pre-release version" of Sprockets. I'm trying to use this in a production app, and I don't think that I'm being unreasonable by expecting to be able to do this with stable versions of libraries. The article is 3 years old, but I can't find a more recent version.

• How do I use ES6 (ES2015) in a ruby on rails app?

  • Has a few suggestions, but none of them are self-contained solutions, and this is almost 3 years old. I expect that there's a specific, stable way to do it by now?

• https://revs.runtime-revolution.com/want-to-use-es6-with-rails-right-now-webpack-to-the-rescue-ebefb2004e9e

  • This is pretty much what I'd do if I had to do all of my ES6 support outside of the Rails Asset Pipeline. Surely, there's a way to do this without stepping outside of Rails and compiling my Javascript code manually?

• https://github.com/babel/minify

  • Still in beta. I'm trying to use this for a production site.

after moving my Ruby on Rails app to production server (AWS EC2 Amazon Linux 2018.03) pages don't render, because of error "The asset 'application.css' is not present in the asset pipeline" (precompiled files are presents in public/assets): production.log

However, when I refresh my application (sometimes more then once), this file is found in cache and page is rendering correctly. It seems like server doesn't wait for file precompilation or something like that. It happens not only on first page entry, but every change of view.

I followed tips from post: application.css not in asset pipeline, but it didn't help.

My stack:

• ruby 2.6.3
• rails 5.2.3
• Unicorn 5.5.1
• nginx 1.14.1

I will be really grateful for any hints.

spring boot version: 2.0.4.RELEASE asset-pipeline version: 3.0.3

Hi

we're using this plugin, because we know it from our grails applications. We liked it, because it has a simple configuration (for our requirements)

Now we're developing a spring boot application and we used this plugin too and we're (almost) happy with it.

But when we run the application in the development mode the assets don't have a digest like /assets/my-styles-b5d2d7380a49af2d7ca7943a9aa74f62s.css

How do i configure the plugin to create a digest for all our resources?

currently we're using this configuration:
