I have recently installed IntelliJ, to learn Java. I have been learning Java previously in Eclipse, but a lot of Seniors have suggested me to start Developing in IntelliJ as it would Save time in Future.
Now the Problem is the Environment is totally different, I cannot add packages directly, i have to configure a lot of things, which is making me confuse, as to which option i need to correctly run my applications. Can anyone help me out how to go about it.
IntelliJ is definitely different from Eclipse so a little reading on the Getting Started pages is helpful. For me, understanding the modules part was the hardest.
For migrating from Eclipse, they have a pretty good tutorial besides the IDE options to import Eclipse projects.

I was using Eclipse for developing Spring boot project. Eclipse is soooo slow in running, so I decided to change my ide. Most people recommend intellij which support majority of extensions for java. However, it is not for free (I know there is free version, but some said compare to Eclipse there are no difference between them. maybe? idk..) and some people said it is a bit slow (not like eclipse but little bit slow). I know people are not using VScode for spring boot, they support some extensions yet compare to intellij it is almost zero base starting. However, upside for vscode is free and light for developing small (maybe middle?) size project. What would you recommend?
additionally, right now I am testing whether vscode can run spring boot
vscode cannot import any annotaiton or collection or anything just loading kept showing.
anyone know solution? since almost no one is using vscode for java there seems to be no information
i'm using vscode for springboot+vue projects. everything works fine.
A couple of years ago I started an open source project that used javaFX + jdk8 to create a desktop application for windows. A few months ago I decided to continue improving the project and make it a little more professional and easy to work on. For that, the first thing I did was migrate to JDK 11 and include Maven. Right now my project starts up and works fine in the IDE. But I am finding it very difficult to compile and package it.
A few months ago, I created another desktop application with javascript and electron. I loved that with a couple of commands, the application compiled and packaged automatically for windows, mac, and linux.
I am trying to do something similar with my java application. That is, use some tool that allows you to make all this ready and automated. I don't know if Maven has these features or if I need to use other tools. I know there are solutions like "launch4j", but what I'm trying to do is create a system that does everything with a couple of commands. The idea is that anyone who downloads the project will have it easy to package the applications.
So the question would be, now that I have a working project, what system do you recommend using to package my project? Which way should I go?
The way to go with this is use the jpackage tool which is made exactly for this. Here is a tutorial which explains how to use that with Maven. https://github.com/dlemmermann/JPackageScriptFX
As a student in a software development class I have been assigned to be part of a group project. Naturally our 4 man group decided to make a game. I suggested LibGDX and got a team member to try it, however, when he tried to import the LibGDX project I created in Windows into eclipse on his linux computer it gave him the could not find sdk message. The build was trying to use the SDK path that I had specified in my own windows computer.
Is it possible to have multiple members on different platforms develop with LibGDX. Please let me know if this is not possible, I have already invested multiple days learning how to develop with LibGDX, and hope that there is some way to develop with windows and linux.
Our team work with libgx projects on MAC, Linux and Windows without any problems. Of course you must properly install Android SDK and JDK in every environment, all other dependencies gradle will download for you. I recommend you to use git for effective team work. You can create remote repositories for free on github or bitcucket.
About IDE, I personally prefer to work with Eclipse, but I know lots of people who works with libgdx in IntelliJ. You should just choose what is more comfortable for you.
P.S In order to fix error with SDK your friend got in Linux look at this answer: Importing gradle project, android error
I would actually recommend using a different IDE, I use JGrasp, I recommend that. If it still doesn't work, try to uninstall and reinstall Eclipse, that helps a lot for my friends who use Eclipse, for some reason, Eclipse seems to fix connection issues to dev kits and what not (my friends had the same issue when they were trying to use JSON data). For me, JGrasp handles connection and linking better than Eclipse when it comes to simplicity of it.
I am on a project that uses GWT/ eclipse/ SQL Developer and the guy who originally implemented it is no longer on the project. We have a normal WAR and everything but the jsp files are kept in a different environment. Anyone know why? Can they not be run through GWT?
The issue we are facing is the only way we have to test/ compile JSPs is to actually deploy it into DEV which takes a lot of time. So we are in need of being able to run JSPs locally.
I have been told someone used to use Jdeveloper to do this, but I am unfamiliar with it and the only YouTube tutorials are in a foreign language (in regards to using JSPs with JDeveloper 11g). Someone else suggested notepad/ Tomcat? Or yet another option would be to configure eclipse to run it with our current project in GWT?
I am not familiar with any of this being I am brand new to JSPs,Tomcat, etc. and am in desperate need of some help.
What is the best way to accomplish my needs and are there any guides/ tutorials to help me through the process?
My requirements are just to run a folder with 4 linked jsps and be able to connect to the database to provide the information.
"I am not familiar with any of this being I am brand new to
JSPs,Tomcat, etc. and am in desperate need of some help."
That's sounds true!
One answer about the different environments is that jsp needs "EE" .I.E. EclipseEE but the GWT app just uses plain old eclipse (like an eclipse helios release with GWT plugin).
Regarding your requirements, I can't understand them clearly enough to begin to provide helpful information, but good luck.

Over the past year, I've heard an increasing amount of hype regarding the Scala language. I know that there are several existing projects that have plans to integrate Scala support with IDEs; however, it isn't always clear how good the integration really is.
Do they currently support Intellisense as well as Eclipse and Netbeans do for the Java language? Do they support instant verification as well?
I can't personally speak to the stability of the IntelliJ or NetBeans plugins (though I have heard good things), but the Scala IDE for Eclipse just recently made a new release with Scala 2.7.4. Architecturally, this release is quite different from the previous ones in that it uses Equinox Aspects, the officially supported mechanism for extending JDT (and other cross-plugin extensions). Whereas before the Scala plugin had to literally hack into the JDT internals using private APIs and reflection to trick the system into behaving properly, now it is able to simply declare its extension points and let the system do the rest. It's hard to even describe how much more stable this makes things. I'm not saying that it's all sunshine and roses yet, but if you've tried and rejected the plugin in the past (as I had), it's time to give it another look.
As for how it stacks up feature-wise, SDT doesn't have any refactoring support (IntelliJ has some basic stuff like "Rename"), nor does the editor do some things like "Mark Occurrences". However, it has a significantly better Outline than NetBeans, better compiler support than IDEA, and very good semantic highlighting. All three plugins support content assist (or "intellisense", as Microsoft calls it), but none of them are particularly reliable in this area just yet. The Scala IDE for Eclipse is the only one to support incremental compilation (alla Eclipse's Java tooling).
My advice: shop around. Try all three and see which one works the best for you. From what I've been hearing, the Scala IDE for Eclipse has leap-frogged the competition with its latest release, but the others have shown such consistent stability and steady advancement that you can't count them out just yet.
Here's a similar question:
Which is the best IDE for Scala development?
In my very short experience with the Scala IDE for Eclipse and the Scala Plugin for Netbeans, it seemed like the Netbeans plug-in was a little more solid than the Eclipse one.
With the Scala IDE for Eclipse I was having problems with running a Hello World-type Scala object, and sometimes the syntax highlighting would start acting up. Then, I tried out the Netbeans plug-in, and it seemed to be more functional than the Eclipse one.
I haven't used either Scala IDE plug-in much in-depth, so I can't speak out of a lot of experience, but just from my initial impression, the Netbeans plug-in seemed a little bit more stable than the Eclipse one.
Currently, all three main IDEs are at roughly the same level of support.
IntelliJ - the plugin has fits of not working at all, but is otherwise quite good. The underlying platform is sluggish (at least in linux) since v8.
Eclipse - the plugin is receiving a lot of support and is under very active development.
NetBeans - IMHO, the plugin works a little better than the Eclipse one, but not being able to run arbitrary files is a major downer.
All of the above suffer from being unable to parse the AST in all contexts. It is quite easy to confuse them by mixing in traits with implicit defs, for example. No IDE can be trusted when it advises of a syntax error. Fall back to the compiler to be certain.
I'm quite happy using IntelliJ IDEA 8.1 and its Scala plugin and can recommend it. It even has a roadmap that you can influence by voting your favorite missing features :) I don't have experience with the Scala support of the other IDE's, unfortunately.
I'm using the Eclipse Scala plugin. Its pretty good but not at the same level as the Java tooling.
AS for intelliJ, no idea.
But between Eclipse and Netbeans, I must say Netbeans especially if you are not willing trade maven for sbt and you want an IDE that does not get in the way of maven.
Netbeans maven support is just way too good.
The Netbeans scala editor seems to work quite nicely as well.
I care not for the integrated scala development kit in netbeans or the compiler plugin, or any such helpers. From netbeans I expect only tthree things:
(a) Do not get in the way of maven and let maven run my build
(b) Give me a decent editor
(c) Let me drill down from my .scala files into the source code of the libraries referred by my maven dependencies.
And Netebeans is able to deliver all three quite well, I belive, even if at times it feels a bit too slow.
What I can say is that
(1) You do not run into any compilation issues since the task is up to maven.
The maven compiler plugin is a bit too slow. But compiling scala vs java is always like that, painful. Still if you've tried GWT compiling java to javascript is more painful even.
(2) Netbeans figures out the source code to you maven dependencies flawlessly and you can drill in into the most obscure sacala operators, such as the CSS mappers of lift.
As for eclipse, eclipse maven integration has always been nasty.
Netbeans maven integration can turn very sour if you have a big project with too many dependencies and modules. Then the check for external changes done by netbeans is just horribly slow. That is the downside of netbeans.
However, if you are and SBT fan ... well, maybe then answer might be something else.
But for me, since maven has become the thing it is today, I never want to go back again to those "web application project", "library project" etc... wizard like options that you have when you create a new project in the IDE.
I simply want "maven project", and please figure out what my output artefact is by reading the pom.
