I'm working on developing a Jar artifact on IntellIJ 14, and I'd like to know if there is an easy way of obfuscating the code prior to sending it to my clients. So far, everybody talks about IntelliGuard, but the plugin was only maintained up to IntellIJ12, and it throws an exception when trying it on the newest versions.
Another option that I have read about is ProGuard, but I cannot find an step to step manual on how to make it work with IntellIJ.
I'm very curious if someone knows how to make any of the two work on the new version of the IDE, or if the know of any other method of obfuscating my code.
Thanks,
Cris.

I have been having trouble utilizing Javafx within Intellij. I run into the error "JavaFX runtime components are missing, and are required to run this application" that I see a lot of other people have.
My main question is do I need to download Javafx12 sdk. I am able to use Dr.Java to run some of my old javafx projects just fine after adding an extra class path and I haven't needed to downloaded anything. It doesn't seem like I need to download anything as another much more basic IDE is able to run javafx. So why does it seem like intellij requires an extra download?
If you moved to Java 12, then yes, you need to download the JavaFX 12 from their new website https://openjfx.io. Luckily installing it is pretty straightforward and well-explained.
It worked before because JavaFX was shipped inside the JDK distribution, which is no longer the case. Swing however is still there and will work as before. (I am not saying you go back to Swing, just that it is still shipped along the JDK)
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
Pentaho Data Integration 8.0.x is using Janino 2.5.16, released in 2010 for compiling the User Defined Java Class step. There is a JIRA in pentaho for updating this to use a newer Janino version which would bring new java 8 related features in pentaho v8.2.0 GA. But there is no info on when will this be released.
Is there any other way I can use a newer janino version (janino-3.0.8.jar) with exiting pentaho for UDJC? I tried to copy updated jar in the lib and also added commons-compiler-3.0.8.jar to fulfill dependency. Now when I open Spoon, I get the following error:
Please advise on how this can be achieved. I understand that just replacing the jar may not be enough but just want if something else can be done.
This is not easy. Even now, since you got ClassNotFound, public api of janino is changed. Some classes are removed some are changed. What is actual needs to update it?
If you need really complicated business logic, then create custom plugin. Documentation and tutorials are available and you can look into sources of current builtin plugins (sources are available on github).
What important new version of janino has, that old doesn't (beside java8 support)? Checkout kettle engine, look into sources of UserDefinedClass step, change code to support new janino version, test and make own build of pdi kettle, and try to send push request to maintainers of repository.
Any of this quite complicated, This plugin is builtin into engine, and you have to make own build. Own build means, you have to support it by yourself. This is non trivial, project is huge and now even bigger and continue evolving, I spent several days to make my first custom build (version of 4, was in ivy) just for purpose to know better and debug complicated cases, and it used never in production.
Maintainers of repository must have good reason to include your changes into stream, it must be well tested and it is long procedure and most probably doesn't worth it. A lots of changed since 2010, I probable have seen in release notes, new version of java already have abilities to compile at runtime.
My advice is to make you own plugin.
I've recently started using Elixir and I'd like to keep my code files in quite decent order. So I installed Elixir plugin for Intellij: https://github.com/KronicDeth/intellij-elixir, but stuck with trying to start an Elixir project. Could you give me some tips how to make new Elixir project?
I'm the maintainer of intellij-elixir. Please file support question as Issues on github: https://github.com/KronicDeth/intellij-elixir/issues. In fact, someone already asked a similar question (https://github.com/KronicDeth/intellij-elixir/issues/77). In summary, right now you can't create "Elixir Project". There isn't yet an "Elixir Project" feature/action although you're welcome to open an issue to make that a feature request. (It's nice if you open it instead of me opening it for you as you'll be subscribed to updates then.) With the feature set as is, you can create any type of project you like because all that matters is that the file extension is .ex for the Syntax Highlighting, Grammar parsing, Inspections and Quick Fixes to work. I just create the default Java project when testing intellij-elixir in Intellij or an empty directory or project layout created by mix new in Rubymine. Since two people at least have brought this up I'll add something to README after I'm finished with https://github.com/KronicDeth/intellij-elixir/issues/59.
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!
