Eclipse fire up - eclipse

I'm re-installing Eclipse, after I installed Android Studio. To do so, I deleted and re-installed all Java installations. Now I can't start Eclipse even I have jdk and jre installed on my machine. I'm getting this message " A JRE and JDK must be available.
Any ideas what I suppose to do?

If you are using Windows.
Install the Eclipse according to the system you are using i.e., is it a x64 or x86, and Install the Java x64 and x86 Accordingly.
how to know my PC running the 32-bit or 64-bit version of Windows?
this should help.

what is the eclipse compatible version for openjdk1.7 in windows 7 64 bit OS

I have windows 7 64 bit OS in which I used to work with eclipse Juno Service Release2 version and Oracle JDK 1.7. Now as per my new project requirements I had to change my JDK from Oracle JDK to OpenJDK 1.7. I have un-installed all the other jdk's from my machine and installed OpenJDK1.7(64 bit version). Now I am facing issues with eclipse, I am able to open eclipse IDE but if I perform any operations like opening an existing project or trying to run any programs/project it is getting crashed or getting hanged. I have to end the process from the taskbar and try again and again. Below is the popup screen that I am getting after eclipse crashes.
Can some one tell me how to resolve this issue? I have seen some blogs saying there is a bug with eclise and OpenJDK with Ubuntu and mac OS but no issues reported for windows. So if there is way to fix this issue please let me know (or) please suggest any eclipse version the is compatible with OpenJDK1.7 and windows7.
Here is my version of solution to my issue which was mentioned above.
Installed Oracle JDK1.7 on my system and did not set the path for this. I have updated the eclipse.ini file with (found in eclipse root directory)
-vm
C:/Program Files/Java/jdk1.7.0_79/bin/javaw.exe parameter. so that Eclipse starts with Oracle jdk
and in
Eclipse->Windows->Preferences window
under Java->Installed JREs->Add(under Installed JREs)
added a new entry to point out the OpenJDK1.7 version so that my project uses OpenJDK version. This solved unusual crashing of Eclipse

e(fx)eclipse with eclipse Luna and Java8

I m trying to use e(fx)clipse with java8 and eclipse Luna on my mac (yosemite).
In a terminal : java -version gives me
java version "1.8.0_25" Java(TM) SE Runtime Environment (build
1.8.0_25-b17) Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)
In my eclipse.ini I m putting :
-vm /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java
which points to my java8 folder.
In eclipse I ve set up the java8 jre.
But when I open eclipse I m still getting :
You are not running your eclipse instance with Java8 ....
I can't get where I am wrong. Any clue?
Thanks.
I had faced similar issue when I had installed JavaFX eclipse plugin in a 32bit eclipse (Luna). It seems, though you have 64bit OS and 64bit JRE/JDK, and you have setup Environment Variables, you will need 64bit Eclipse to run JavaFX under Eclipse.
Hence, make sure you have 64bit Eclipse running on your machine. If it is a 32bit machine, then there won't be any problem as neither we could install 64bit JDK or 64bit Eclipse.
I hope this solves the problem.
Thanks

Upgraded to Pydev 3 not working with eclipse 4.3 Kepler on Mac 64 bit cocoa

I have tried using a clean workspace and a fresh installation of eclipse with nothing but pydev. In all cases, I don't get the pydev configuration options or preferences or views. The plugin install goes through without a hitch and I can see pydev in the installed software also. Anybody else face the same?
PyDev 3 requires Java 7 to function. Unfortunately, the version of Java that is installed on Mac OS X is not a compatible or recent version.
You can check the current version of java on your system by typing java -version in the terminal. In order to run PyDev 3 you should have version 1.7.xxx.
To update Java you will need to install a Java Development Kit (JDK), since just installing the Java Runtime Environment (JRE) will not update the symlink at /usr/bin/java on OS X. If you think that you have installed Java 7, but java -version still gives you a version of 1.6.xxx then you probably installed the JRE instead of the JDK.
I agree with pseudocubic, In my case I just downloaded JDK8 : which by the way includes the JRE8 so pydev worked without trouble in my mac . I had to do this after installing JRE7 but when checking in console java -version it was returning 1.6 version (despite the fact that checking at java icon in system preferences says 1.7 was installed)
Install JDK8 and it's done

Ubuntu 12.04 Eclipse Indigo wont start

Please help :( My Eclipse Indigo wont launch. It shows the small blue rectangle and then hangs on that. If I then bring another window infront of this the blue square is now grey. There is no error and there is no error log file in the .eclipse folder.
My Ubuntu 12.04 has been acting funny. The software installer doesnt work and there are errors in the update manager. I finally did command line -update using apt-get and since then my eclipse has been broken.
System :
Ubuntu 12.04 X 64
java -version
java version "1.7.0_11" Java(TM) SE Runtime Environment (build 1.7.0_11-b21) Java HotSpot(TM) 64-Bit Server VM (build 23.6-b04, mixed mode)
I've been burned in the past by the Eclipse package bundled in Ubuntu's repositories. I would recommend downloading directly from Eclipse's website and run from there.
If you're having problems launching the Ubuntu-version, extracting and running manually should give you some indication that the problem is with Java or Eclipse.

Not able to run Eclipse Galileo

I am trying to run Eclipse Galileo, but having following error message on screen:
I have installed jdk-6u21-windows-x64 and also added the environment variables in the PATH. I am running Windows 7 64-bit.
If you're going to use a 64-bit JDK, you should probably get the 64-bit Eclipse instead. They really should match.
