I have read almost all documents pertaining to this topic and i haven't found the precise and correct answer.
I followed this link
The exact problem i facing is that i have followed this document and installed a 32 bit SWT. Now when i ran my program i came to know that i should have used 64 bit SWT with 64 bit JVM from here. I downloaded a 64bit version following the link in one of the answer. but when i tried and repeated the process of importing it says i already have a project. Now i am not able to put that 64bit SWT in my project.
Can anyone help me out with this.
Please keep in my mind i am new to JAVA and this is the first time i am using Eclipse RCP.
I found the answer here
Actually i went to the workspace location manually deleted the project and voila i was able to import again. and the program ran. Thanks for your suggestions

so I have a problem. I accidentally deleted Eclipse folder and I wanted to install Eclipse again. But when I run installation it freezes the moment I run it, and I have to exit it...please help me
It would be informative to observe and mention any system error during installation attempt. By the way, I hope you are installing the right version for your operating system and more so, you have the recommended system requirement like RAM size, processor speed. I suggest:
Restart your system.
Use a system tool like Advanced System Care (free) and scan your system.
Well, I don't know what happened but I tried to install it 2 times, it freezed and didn't work. When I tried third time it worked. :D So yeah. Magic.
I had the same issue. Everytime I tried to install Eclipse, the installer froze at some point. Turned out it was a problem with the firewall. I tried the installation over a hotspot from my phone and it worked.
Might not be the problem for you, but I thought I leave this here, as I was trying for quite a while and almost gave up.
I'm trying to get EclipseFP (Haskell support, but the original coder stopped maintaining it last month) working on my iMac but everything seems to fail constantly. I've been debugging this for hours now and like most other Haskell stuff there isn't much decent support out there regarding the installation of such tools. I haven't even written a single line of Haskell code yet (apart from some playing around in GHC/GHCI which surprisingly did work)!
I've tried so many things already, different libraries, different solutions, different versions etc. But it seems that everything that has to do with haskell support is just one big clutter of confusion for me and nothing seems to point me in an apparent direction which bothers me since I am an experienced programmer and dealing with command line interfaces, tools and dependencies isn't unknown to me on all sort of platforms for years now.
Even the most relevant topics on StackOverflow or other knowledgebases just won't cut it regarding this topic and I'm starting to feel like dropping the entire Haskell language and just use something which does play nice with the system without such troubles since it is already such a pain in the ass to get the most basic development tools to work, let alone the coding itself...
The things I got:
Mac OSX Yosmite
GHC
GHCI
Cabal (repository)
Eclipse Luna
I've installed EclipseFP using the install instructions which worked out all great. At this point I thought it would just all work without any problems as the plugin installs just fine...
Well, that was not the case of course. I've restarted Eclipse as it requested after installing new plugins. Here is where the trouble begun..
In the following steps I would have to open the Haskell Perspective in Eclipse. Well... guess what.. there was none! After strolling the web I found out that it might have compatibility issues with the old JDK 1.6 which was installed by default on MacOSX. No worries.. I've downloaded Java JDK 1.8, set it up in Eclipse, restarted it. And there the item "Haskell perpective" showed up in the list.
After clicking that, and thinking my troubles were over (and I could finally start coding!) nothing happend! I've searched around for a while and found the Eclipse error console which until this day gives me nothing more than:
An error occurred while automatically activating bundle net.sf.eclipsefp.haskell.ui (459).
org.eclipse.e4.core.di.InjectionException: java.lang.RuntimeException: org.eclipse.core.runtime.CoreException: Plug-in net.sf.eclipsefp.haskell.ui was unable to load class net.sf.eclipsefp.haskell.ui.HaskellPerspective.
Of course I have tried solving this issue and came across some dependencies which needed to be installed using cabal (BuildWrapper, Scion-Browser and some other essentials). After doing so I still have the same problem and I have no idea where to look for. The only information I can really find are topics which are more than 3/4 years old which share 0 relevance to my exact problem.
I could paste the Java stacktrace here as well which came with the error message, but it doesn't show much useful information anyway other than just basic crashing.
I hope someone can help me because I would really like to start coding now for a change instead of wasting hours on getting my basic development framework/IDE set up.
Long story short; I'd like to code some Haskell in Eclipse but the development tools just won't install and/or work properly without any notable errors or directions to look for.
I have been using Linux for less than 24 hours, so please, if there is anymore information I should provide, do be quite specific about how to get that information.
I've been trying to install Node.js, express.js and eclipse. As you can see, ubuntu does recognise both node.js and express as installed on my system (I think!) and I got the Nodeclipse-extension for eclipse, but still Eclipse doesn't seem to recognise either node.js or express (see my image below). I also want to add that the time occurrence of the error, I was trying to build a Node.js Express Project.
At this point, how do I go about debugging the situation? The folder location shown in the image does not fully exist. I can only go as far as [...]/bin/ - I have been looking at error messages similar to mine, and it seems like people are getting such errors because they're lacking an installation, however, from my screenshot provided, I would think everything is installed as needed.
I am using a native 64-bit windows laptop with Linux (Ubuntu) installed through a virtualbox. Ubuntu is 14.04 LTS and just 32-bit, as I don't have spare 2 gb ram to give the 64-bit version. Sadness.
I'd appreciate any help!
In Eclipse Windows -> Preferences -> Nodeclipse
check what is configured for Node and Express
Read more on http://www.nodeclipse.org/
I found a solution, which worked for me:
WINDOWS:
I did double installations of the needed modules. They were both located in C:/Users/X/AppData/Roaming, in the Eclipse directories and finally in C:/Program Files/nodejs. When I deleted all the node_modules, besides critical ones for nodejs to function and then ran Eclipse with Nodeclipse, it seemed to function and Eclipse automaticly defined folders in its own subdirectory, in which Express were located.
UBUNTU:
Delete all node_modules files and run Eclipse with Nodeclipse. See the windows explanation for a more detailed overview. Same problem and solution seemed to be present for both systems. Do note that the file directories are of course not completely interchangeable. You'll need to locate your instances of node_module.
I was able to run Eclipse until I tried to install another compiler, suggested by a online tutorial for C++. Now I'm getting the 'No virtual machine was found error'. I know I'm suppose to match the versions of the programs but I can't seem to figure it out. I thought I had downloaded 64 bit version of each program in Eclipse and JDK but I don't know how to verify it. I go to each file and try to get the info but I must be looking in the wrong places. I have copied the file location of JDK and pasted it in the Advanced System Settings in Environment Variables. In the Systems Variables for User on the variable line I typed "path", on the value line I pasted the location: C:\Program Files\Java\jdk1.8.0_05\bin. I have even uninstalled both programs several times and reinstalled them. I've been at it for several hours now with no success. Any suggestions, anybody. Thank you.
I am working with Lejos and java Eclipse on Windows 7. As my machine is 64 bit it will not allow me run the standard Lejos driver as an Eclipse plugin I installed it as an external tool . I followed this super helpfull tutorial http://www.youtube.com/watch?v=hEFA0DdFhm8 However for my project I need to be able to regularly send instructions to my Nxt brick. is there anyway that I can call external tools from the main application while it is running ??Alternatively is it possible to call batch files in main programs or even make command line arguments while a program is running ??? I have read allot of forums on this and no where have I found the solution to my problem, if people have any Idea I would appreciate the help,
Thanks.
Right after allot of reading around there is and article on java world
http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html?page=1
that sums up beautifully what you should and shouldn't do .. hope this is helpfull for anyone coming after me ......
