I'm trying to build a simple JavaFX application in IntelliJ environment using Gradle and OSGi, but I could't find a simple working example anywhere.
Most of the solutions I've found are not Gradle based or they use some additional tools, or they are outdated and they simply don't run, or they import some magical "hack code" from github etc.
The tools I've found for similar purpose e.g. e(fx)clipse, bndtools are probably not important if I use IntelliJ. Moreover the bndtools tutorial is very wordy and I couldn't find a good starting point or quickstart to try those things out.
I know the basics about Gradle and OSGi and according to information I've found, it does not seem to be an easy task to solve.
Are there any (good) tutorial(s) or quickstart(s) about how to start this kind of project properly? A simple working example would be very useful.
The e(fx)clipse project is a good starting point and provides many useful features for using JavaFX and OSGi.
See http://www.eclipse.org/efxclipse/index.html .
The blog of one of the developers has also many useful tips, https://tomsondev.bestsolution.at/ .

firstly, I want let you know how useful this community is for me, I was stuck on an error
`Error: JavaFX runtime components are missing, and are required to run this application`
and thanks to this answer I actually solved: link
However I've a couple of questions. I noticed that IntelliJ doesn't change the configurations (Like set the VM option and pick the right library for the javaFX project), so each time I've to create a new JavaFX11 or 12 project I've to being throw all the manually settings again.
There's a way for set a "default behaviour" for the IDE ? It's really cumbersome.
The second question is, how I can use all the beautiful framework that the developer community offer for JavaFX? I've seen on openjFX a couple of interesting framework like TilesFX or CalendarFX but there's no information on how implement them on my IDE neither on GitHub nor here.
I have seen that most of them uses Gradle files, but honestly I don't have the faintest idea of what this kind of file does and how implement it on IntelliJ. Thank's to everybody.
Run the project with a more recent JDK like JDK11, for example.
If it does'nt work, you probably forgot to change the JDK of your builder in IntelliJ!
Open the settings and follow the path as bellow:
FOR MAVEN
FOR GRADLE
In IntelliJ, I have to manually import Flutter packages at the top of the file in order for auto-complete to work elsewhere in the file.
I was rather hoping I could start typing something (in a method) and IntelliJ would search my pubspec.yaml and locally within my project and suggest classes I might want. If I selected something that wasn't already imported, it should import it for me.
This basic functionality is available in many other languages and IDEs, so I'm wondering if I've got something misconfigured. I'm using IntelliJ 2018.2 with the latest Flutter and Dart plugins installed.
This is a known issue.
For performance reasons the DartAnalyzer was built to only load libraries that were imported anywhere in the projects code already.
The overall performance of DartAnalyzer was improved a lot since then and it would now allow to provide better suggestions, but it seems there weren't enough resources available yet to get it implemented.

I've used DCEVM hotswap technology in eclipse and IntelliJ IDE which was pretty cool feature. By using DCEVM in IDE what I can do is, I can change into the source code i.e add/remove/edit method, classes, properties at the runtime without doing restart the program.
Now my question is:
I want to apply the same features in my running application which is run without using any IDE. To be more specific the running applications source code(compiled code) can change on the fly. And for that bytecode how to deploy on DCEVM for runtime hotswapping?
What I've found is:
We can do hotSwapping without using IDE for that we can write own JNI code to directly hook into JVMTI and trigger a hotswap.
any idea/help would be much helpfull. thanks
Fortunately I found the solution.We can use the HotSwapper plugin to solve this kind of problem. The same question is asked in dcevm discussion forume:
https://groups.google.com/forum/#!topic/hotswapagent/Uk3cUdkHNYQ
Although the information from this link https://news.ycombinator.com/item?id=3198497 is very helpfull but it was asked four years ago, so that I was stuck in.
Now the DCEVM is being more smart It can support various plugin such as Hotswapper, AnonymousClassPatch, WatchResources, Hibernate, Spring, Jersey2, Jetty, Tomcat, ZK, Logback, JSF, Seam, ELResolver, OsgiEquinox and even we can write own plugin too which is more easy to develope.
I really like the idea of this BundleTransformer plugin from NuGet, and I see that they have LESS support. But ...
After weeks of trying, I cannot find any decent example of how to use it. The documentation is unclear, to say the very least. This is the closest I could find, which does not compile or work.
who-could-ask-for-more-with-less-css
Well, the simple answer is that I could ask for more.
Can someone please assist me with the simple task of creating a bundle that has .less files in it, that will run? I am completely lost.
I would suggest reading the wiki page for bundle transformer and also, as the wiki page suggests, make sure you are familiar with ASP.NET bundling and minification.
If you follow the examples of usage you should be up and running.
I know this is an older post but figured I'd chime in. The Bundle Transformer Codeplex discussion board (Feb 2015) mentions that BundleTransformer is no longer considered a modern client-side build tool and they are recommending you go with Gulp or Grunt - which both have support starting in Visual Studio 2013.3 via VSIX extensions and more baked in to VS2014. FYI -This Scott Hanselman post explains how to get up and going with Grunt and Gulp in Visual Studio. I think if you're using BundleTransformer for simple Less compilation it works fine, but doesn't allow you to do things like generate CSS Sourcemaps which make your browser's dev tools aware of the Less source files, which in my humble opinion is critical for using a CSS preprocessor - the ability to see the LESS line numbers of your source files in the styles pane.
What is the right way to make an RCP application that is “ready for plugins”? I have struggled to do this basic concept and am trying to accomplish this in Eclipse 3.7 (latest 3.x version).
Step 1
I would like to explore this by using 3 eclipse plugin projects:
• HelloWorldRCP
• HelloWorldPluginA
• HelloWorldPluginB
Would it make sense to make HelloWorldRCP with all the common things such as a menu-bar with an Edit menu including cut, copy and paste menu items? The HelloWorldPluginA could add an additional menu-item called “Alpha” and HelloWorldPluginB could add yet another menu-item called “Beta”? However, the cut, copy and paste functionality could still work within Plugin A and B?
Step 2
Next, how do I deploy this as a “product”? I have made a new product configuration and defined the dependencies from the default runtime configuration that was made. I do notice that there are a lot of dependency jars that are included, but I don’t think I use them. For example, I don’t use data-binding to my knowledge, but it keeps coming up as a required dependency.
I go to Export | Eclipse Product and an executable environment is created in my desired folder. However, when I copy this to another machine it seems to keep referencing the original machines Java installation location. How does one get around this?
I have tried to bundle a jre with the Product Export but nothing is created. I have also just tried copying my jre6 as a jre folder. This does seem to work.
Next problem here is the 32/64 bit Java execution environments. What is advised here? I have been aiming to build on 32 bit only and then hopefully that will run on 32 or 64bit platforms. Is this correct?
Step 3
I need to web-start this now. The old way of initiating an Eclipse 3.5 application, using a startup.jar has changed. I now use the equinox launcher and reference it in the jnlp instead of the startup.jar. However, I keep getting an exception which seems related to the 32/64 bit equinox win32_64 jar. I notice that the export writes a folder and not a jar. I read somewhere that this is a “clever trick” to allow compatibility for both 32 and 64bit runtime environments.
The problem here is that I need a jar and not a folder so that I can sign the jars required and deploy accordingly.
Does anyone have a Java Web-start example for and Eclipse 3.7 RCP application? Or any advice?
You are going to need a lot of time to learn everything you've asked about here.
Here is one of the best places to start... http://www.vogella.com/eclipse.html
That site covers a lot of basics. But you need a little more than basics.
The best example of a working RCP product with some of the features you require can be found at ... http://max-server.myftp.org/trac/mp3m
This guy (Kai) makes all of the source code available via SVN, and he has some very advanced stuff going on in his application. He also has a good blog with some advanced RCP tips and tricks. http://www.toedter.com/blog/
Another thing you'll want to investigate is Tycho. I realize that you didn't mention anything about building your application, but I've found that using Tycho for building has made my most recent foray into Eclipse RCP 100 times better than the other times I've done RCP work. So, my advice, get to know Tycho. http://wiki.eclipse.org/Tycho/Reference_Card
The learning curve of Eclipse RCP is somewhat steep, but I think it's worth the effort.
Good Luck!
