We Keep Coding

I installed Java 7 but Eclipse keep saying that 1.6 is not suitable for this product

I'm using latest version of Eclipse Luna on Mac OS X 10.9.4. Whenever I try to open the Eclipse it says "version 1.6.0_65 of the JVM is not suitable for this product, version 1.7 or greater is required". I installed java 7 (JRE, I don't need JDK) but still I'm getting the same error. I tried java -version and the output was "java version 1.6.0_65". I can see the java icon on my system preferences. I also restarted my Mac to see if that works but that doesn't help either. I searched on google and some people suggesting other users to change Eclipse.ini file, the instructions wasn't clear and I'm a java beginner so I've no idea where and what to edit. Any step by step instructions will be appreciated.

I had this same problem with a fresh install of Eclipse Mars on OSX. I had installed the JRE from https://java.com/en/download/ (which is the top google search result for "java download" for me.
This failed for me with the same message "version 1.6.0_65 of the JVM is not suitable for this product, version 1.7 or greater is required"
Then I saw a comment that I should get the JRE/JDK from oracle instead:
http://www.oracle.com/technetwork/java/javase/downloads/index.html
After downloading the most recent JDK from Oracle Eclipse starts fine.

A potential solution to your problem might be to uninstall Java6 (provided by Apple itself) and only have Java7 installed in your system. This only applies in case you have no applications that desperately need the old Java6 version to be installed.
To remove the Apple-like Java6 installation open a Terminal and:
sudo rm -rf /System/Library/Java/JavaVirtualMachines/1.6.0.jdk
After this step you should only have Java7 by Oracle installed in your system. To verify, open another terminal and do a:
java -version
It should display something like "java version "1.7.0_XX" where XX is the current update version of the Java7 installation. If not: proceed with the next step.
Redefine the JAVA_HOME variable (to support IDEs like Eclipse and other developer tools...), which helps detecting where the "active" Java installation is situated in your system. Open a terminal and (Note: replace XX first!):
sudo rm /Library/Java/Home
sudo ln -s /Library/Java/JavaVirtualMachines/jdk1.7.0_XX.jdk/Contents/Home /Library/Java/Home
Afterwards, a fresh installation of Eclipse should detect Java7 in your system and should work with this version out of the box. You can modify an installed Eclipse to use this installation by navigating in Eclipse to:
Preferences -> Java -> Installed JREs. Then remove the old Java6 system entry AND add new path (see above) with the name Java7.

You can modify Info.plist inside Eclipse.app (right clic on Eclipse.app --> show package contents) and specify -vm after <key>Eclipse</key>.
For example :
<key>Eclipse</key>
<array>
<string>-vm</string><string>/Library/Java/JavaVirtualMachines/jdk1.8.0_20.jdk/Contents/Home/jre/bin/java</string>
<string>-keyring</string><string>~/.eclipse_keyring</string>
<string>-showlocation</string>
</array>

Ensure you installed the jdk 7 or above. If you have a Mac you most likely have 1.6.0.jdk. To check your java development kit (jdk) version go to the terminal and browse to:
/Library/Java/JavaVirtualMachines
Next, if you see 1.6.0.jdk then you did not install the latest version of the jdk. Go to http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html to install the latest jdk. Next use the browse out to the same file path aforementioned and ensure the latest jdk is in there (i.e. jdk1.8.0_141.jdk).

To specify Java 6 for OS X:
-vm
/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/bin/java
For versions of Mac OS X 10.7+ the location has changed to
/Library/Java/JavaVirtualMachines/<''jdk_name_ver''>/Contents/Home/...

How do I run Eclipse using Oracle's new 1.7 JDK for the Mac?
Mountain Lion with Java 7 only
Eclipse still using java 6 as jre on Mac OSX

As I found out, we don't need to un-install an existing Java 1.6. Just installing or deploying a newer version 1.7 or 1.8, and setting the JAVA_HOME, along with the below given activities will solve the issue.
Check your c:/Windows/System32 (as I had this issue in windows). You will find junk java processes (java.exe, javaws.exe etc). Delete them all.
Deleting just java.exe will reflect in your PATH but eclipse still picks the javaws from c:/windows/system32. This is because, usually in PATH, you will have C:/Windows/System32 as the first entry. So, this will override any JAVA_HOME entry in the path.
Try starting the eclipse. It should work like charm! Atleast it did for me.

You might have to disable SIP and reenable it.

Okay so I have been struggling with this issue for a few days with Eclipse Neon and Oxygen. I was doing the below steps -
Check java -version from Terminal. It showed version as 1.7
Go to System Preferences -> Java -> Update Java version. Version 1.8 was downloaded and updated.
Went to Terminal again to confirm and this time it showed the version as 1.8.
But it still didn't work!! What was I missing now??
Here is what you need to keep in mind -- By default when you type the below command it shows the JRE version.
java -version
You need JDK to start your Eclipse installation. Please go to Java download page
and download the latest JDK version and you should be good to go.
Don't try to remove the Java in /System/Library/ - firstly this will not be allowed (you need to login as root user) and secondly you don't know the dependencies this Java version has on your other applications. Hope this helps!

Check your system variables ($JAVA_HOME specifically). This may be helpful:
http://www.mkyong.com/java/how-to-set-java_home-environment-variable-on-mac-os-x/

Install the updated JDK
Update the environment variables: here's how
If still not working uninstall the older JDK

I see that you have installed the Java plugin and not the jdk. You can download the JDK from Oracle Downloads section.
You can remove the Java Plugin and install JDK from oracle downloads to resolve your issue.

I have had the same problem as noted above. I could not get Eclipse to install because of Java incompatibilities. The sequence I followed goes like this:
Upgraded to MAC OS Sierra
Downloaded the Eclipse installer but was prompted that I needed to instal a legacy Java.Installed Java 1.6
Was unable to install Eclipse and was prompted that I needed Java 1.7 or greater. Downloaded and installed Java 1.8
Ran the terminal code 'java -version' // this will check your jre version. This showed returned Java 1.6 despite the fact that I had upgraded to 1.8. The Java version listed in the Java control panel said 1.8
Tried multiple downloads of eclipse and Java and multiple restarts always with the same result.
Visited the Oracle web page. I could not find the above reference to 8u73 and 8u74 but I did find and option to download 1.8.0_12. I did this. It installed without difficulty, and then I was able to install Eclipse without difficulty.

Android Studio Emulator - Java instance does not support 32 bit JVM

I am running android studio on a Mac os x maverick. I have installed the 64bit JDK. When I run the emulator I get the message
Error:Abnormal build process termination:
Error: This Java instance does not support a 32-bit JVM.
Please install the desired version.
in android studio.
java -version
returns
version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)
and
$JAVA_HOME
points to
/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home
So every thing seems to be fine. What could possibly be wrong?
Update:
I still had an old jdk1.6 lying around on my mac. When removing it Android Studio was asking to install Java 6 again. So apparently Android Studio needs Java 6 to compile (as confirmed by Andrew in the comment of this question). Hoping that it would install the x64 version I let it install Java 6. However I still wasn't successful afterwards. I neither could find Java 6 for Mac OS X 64 Bit. Any hints on that?

Android Studio can run on whatever it needs, but the error seems to be pointing to the SDK that the project is using. To check what your project is using, go into Project Structure > Project Settings > Project. You should now see the Project SDK. It should say something like "Android API ## Platform (java version "1.7.[current version number]"). If it doesn't say 1.7.[current version number], then it probably needs to be updated.
Here's what you can do to update it:
In Project Structure > Platform Settings > SDKs, click the "+" button to add a new SDK.
In the pop-up, go into your Android SDK folder and click "Choose"
Another pop-up will appear asking for which SDK and JDK you want to use. Choose any Android SDK and the 1.7 JDK.
Go to Project Structure > Project Settings > Project and change your Project SDK to the one you just created. You should see the name of the SDK with the new Java version that you installed.

I am not sure but I think that sometimes the error is actually stating a falsehood, and is misleading.
I agree with #Maxwell inasmuch as the problem is a mismatch between the JDK configured for the project and the JDK that IntelliJ is running under.
The specific problem I encountered was Running IntelliJ 13.1.1 with 1.6.0_65 ... x86_64 while compiling a project configured with a Java 7 x64 JDK. Reconfiguring the project to an x64 Java 6 JDK put out the fire.

I resolved this issue by doing the following:
Go to File -> Project Structure... -> Platform Settings -> SDKs
Select the SDK listed
Click on the ' - ' to remove it.
Restart Android Studio
Go to File -> Project Structure -> Platform Settings -> SDKs
Select the SDK listed
Click on the ' + ' to add it (follow path to your JDK HOME)
Restart Android Studio, and re-Build your Project.

Eclipse (Java/SWT App): Reconfigure to run as 64-bit

I am trying to reconfigure my Java WindowBuilder SWT application to be 64-bit, not 32-bit.
My development machine is Windows (Win7, 64-bit), but the code needs to run on CENTOS too. Everything was working as 32-bit.
I cannot seem to shake this error. I did see the following articles here on StackOverflow.
issue 1, issue 2, issue 3
As per other developers recommendations, I did the following:
1. I went Window | Preferences and set the JRE to the 64-bit version
I then made absolutely sure to reference the 64-bit version of the SWT file. I even placed the 64-bit SWT in the project's /lib folder.
Steps: Right click project | Build Path | Configure Build Path... | Libraries
The run (project right click | Run As | Run Configuration...) and debug (project right click | Debug As | Debug Configuration...) configurations use the project environment JRE, which is what I set in step 1, or so I think.
I modified the eclipse.ini (with Eclipse closed) and added the following line to the end:
-vm "C:\Program Files\Java\jre7/bin/javaw.exe"
The 32-bit version is in "C:\Program Files (x86)".
I am still new to Java programming, so what step did I miss?
I am seeing the error if I run from the project folder in a command window or through Eclipse using the Debug configuration (F11 in Debug view).
Command Line Error:
Debugging Error:
UPDATE:
I might have answered my question, just not sure. I see at the bottom of this issue that the author said that he overlooked the Eclipse version. I see via the shortcut properties that I am using the 32-bit version (installed into the "C:\Program Files (x86)" folder). As there is no installatino program, I assume that I downloaded the 32-bit version. Could that be the problem? (I am trying the 64-bit version now.)
I would think that switching SWT over like I did would have solved the problem or can 32-bit Eclipse only produce 32-bit and not 64-bit?
That would seem to bring up another interesting question, although the other article answers this question too, that 64-bit Eclipse can build 64-bit and 32-bit Eclipse 32-bit, not mix and match like Visual Studio, even if you do set the libraries correctly. I will see.

I'm answering your "another interesting question".
In Eclipse there is a Feature called 'Delta Pack' which makes Eclipse able to export RCP applications into different platforms than the Eclipse you're looking at. It knows how to make 32/64 bits too.
But it has disadvantages:
1.) It's somewhat slow to export (a half minute maybe)
2.) You have to debug your application via Remote Java Application debugging (on localhost probably)
I'm not sure about the second point; I was fixing a UI bug which only appeared on Ubuntu exports so I had to debug it on a virtual-machine as a Remote app.

Android Studio failed to load JVM on Mac OSX (Mavericks)

I am trying to setup Android Studio on my Mac. It is running OSX 10.9.1 Mavericks. I have installed the latest JDK (at the time of writing 1.7 update 45), and I installed Android Studio. I use Java 7 because I have some Java applications I have to run and they require 1.7. I have not installed Java 1.6, because it is ancient and old. Launching Android Studio from any launcher does literally nothing. Activity Manager never shows it running. I do not want to install Java 1.6.
I did some work and tried to run the executable via command line through the package contents, and for both executables, I get these messages:
I am unsure what I am supposed to do to fix this error. I'm not very adept on a Mac (still somewhat new to it, and its confusing to do power user stuff on this) so if anyone can help me figure it out that'd be great. I'm on the 2013 Macbook Air with plenty of resources for this to run.
Update: This also applies to Yosemite, El Capitan, and all the other versions of OSX that can run Android Studio.

Update 12/11/2014
As of Android Studio 1.0 RC3 you can follow this set of directions to make it work.
I figured it out. You have to edit the android studio's Info.plist file in the package so it uses 1.7. I don't get why Android Studio insists we install and use an outdated, vulnerable version of Java.
Full resolution: http://i.stack.imgur.com/yyYaG.png
To open the package you need to find the Android Studio.app file in the Applications folder and right click it > Show Package Contents.
Edit the plist (I think you might need to be root) and change JVMVersion from 1.6* to 1.7* (or 1.8*, or whatever JDK major version you have). I don't get why that made a difference since my original output said it was using 1.7 anyways.
This fix seems to apply to all of IntelliJ's IDEs (I've seen it on PyCharm as well), though other ones seem to support newer versions of java natively.

As answered by hasternet # Android Studio was unable to find a valid Jvm (Related to MAC OS)
For quick and dirty solution, Follow the answer by Mgamerz; open Android Studio in Finder (CTRL+Click > Show Package Contests > Contents > info.plist) and edit Key JVMOptions>JVMVersion from "1.6*" to "1.6+"
Recommended method as discovered by Antonio Jose is to edit environment variables in MacOS (messing with info.plist is not recommended)
either at program launch (opening the Studio through terminal rather than the icon)
$ export STUDIO_JDK=/Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk
$ open /Applications/Android\ Studio.app
or setting up the environment through AppleScript at every MacOS startup:
do shell script "launchctl setenv STUDIO_JDK /Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk"
do shell script "launchctl setenv STUDIO_PROPERTIES /Users/username/Library/Preferences/AndroidStudio/idea.properties"
do shell script "launchctl setenv STUDIO_VM_OPTIONS /Users/username/Library/Preferences/AndroidStudio/studio.vmoptions"
(Remember to save the script as Application. Antonio Jose managed with just the first line - AFAIK you can use .properties and .vmoptions to set up additional settings.)
Official instructions: http://tools.android.com/tech-docs/configuration/osx-jdk
(The reason why Android Studio want's to run off of JRE 1.6 is because it apparently makes the fonts look better - feel free to go through that "official" route and install JRE 1.6 # http://support.apple.com/kb/DL1572 - you can then set the JDK to 1.8 in the SDK Location settings - local.properties)

mgamerz is right - The release notes give a much better solution for rc3 and onwards - theres a idea.properties file
(or environment variable)
~/Library/Preferences/AndroidStudio/idea.properties
it also shows what environment variables you can use to set things like the jdk
export STUDIO_JDK=/Library/Java/JavaVirtualMachines/jdk1.7.0_67.jdk
ref : http://tools.android.com/recent/androidstudio1rc3_releasecandidate3released

I did below command on Mac Terminal to fix this problem, please make sure java version and path.
$java -version
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)
$ export STUDIO_JDK=/Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk
$ open /Applications/Android\ Studio.app

Hey Friends I just Figured it out a simple way to fix this for Mac users.
Open Terminal and type this -> java -version and hit enter.
Output will be something like this:
Now check your Java Version. My Java version is 1.8
So now we need to Open Contents of our Android App.
For that right click the Android.app and then select Show Contents
Like this
Now there will be Content folder, Open that Folder and there you will find Info.plist
Open this info.plist
And you will see this.
In this expand the JVM
Here you will see the JVM version showing 1.6* but our jvm version is 1.8 (for example my jvm version is 1.8)
So we need to change this number according to our jvm version, so i changed it to version 1.8*
Then click save. And you are done.
Now you will see setup wizard running
And you are ready to start your first android programming app.

I found that downloading an extra Java bundle from Apple fixed the issue.
If you search for this problem then I found the second link was to a blog having exactly this problem, all credit goes to him here
I know that posting links isn't an answer but as you can see from the resolution you need to make sure you have an up to date version of Java and also the Java bundle from Apple, for this reason I have also included the searches needed to get to these websites.
Here is where to download the latest version of Java
If this link is broken then searching "java latest version" return it at the top of the Google list
Here is where to download the Apple Bundle
If this link is broken then searching "Java for OS X 2014-001" returns it at the top of the Google list
For me trying to solve this problem it appears that initially it was an issue that required a work around and then Apple released an official work around download meaning that fiddling in plists is not necessary any more.

Eclipse crashes after opensuse update and no error log

I did a fresh install of OpenSuse 13.3 (64) and downloaded eclipse kepler.
After a (short) while eclipse crashes. It seems to be triggered by using the arrow keys (who do not move the cursor).
I checked .metadata/ in my workspace, it does not contain an error message.
My system uses openjdk 1.7. Because of the error, I installed jdk and jre. I tried starting eclipse with -vm "location of jdk or jre", to no avail. Also added it to eclipse.ini
I also went to settings -> java -> jres and added the new jre.
All of this makes no difference. Is there anything else that I can check to see what is wrong? Or otherwise point me to an alternative of eclipse, because I need to work : )

I've the same issue. Looking in other foruns i found this solution:
Run eclipse as "eclipse -vmargs -Dorg.eclipse.swt.browser.DefaultType=mozilla".
