Re: Eclipse Java 32 Bits
Sofie Kovalcheck
Installing Eclipse is relatively easy, but does involve a few steps and software from at least two different sources. Eclipse is a Java-based application and, as such, requires a Java Runtime Environment or Java Development Kit (JRE or JDK) in order to run.
Regardless of your operating system, you will need to install some Java virtual machine (JVM). You may either install a Java Runtime Environment (JRE), or a Java Development Kit (JDK), depending on what you want to do with Eclipse. If you intend to use Eclipse for Java development, then you should install a JDK. If you aren't planning to use Eclipse for Java development and want to save some disk space, install a JRE.
A Java 17 or newer JRE/JDK is required, LTS release are preferred to run all Eclipse 2023-06 packages based on Eclipse 4.28, with certain packages choosing to provide one by default. The Installer now also includes a JRE--consider using the Installer. Please see 5 Steps to Install Eclipse.
A Java 17 or newer JRE/JDK is required, LTS release are preferred to run all Eclipse 2023-03 packages based on Eclipse 4.27, with certain packages choosing to provide one by default. The Installer now also includes a JRE--consider using the Installer. Please see 5 Steps to Install Eclipse.
A Java 17 or newer JRE/JDK is required, LTS release are preferred to run all Eclipse 2022-12 packages based on Eclipse 4.26, with certain packages choosing to provide one by default. The Installer now also includes a JRE--consider using the Installer. Please see 5 Steps to Install Eclipse.
A Java 17 or newer JRE/JDK is required, LTS release are preferred to run all Eclipse 2022-09 packages based on Eclipse 4.25, with certain packages choosing to provide one by default. The Installer now also includes a JRE--consider using the Installer. Please see 5 Steps to Install Eclipse.
A Java 11 or newer JRE/JDK is required, LTS release are preferred to run all Eclipse 2022-06 packages based on Eclipse 4.24, with certain packages choosing to provide one by default. The Installer now also includes a JRE--consider using the Installer. Please see 5 Steps to Install Eclipse.
A Java 11 or newer JRE/JDK is required, LTS release are preferred to run all Eclipse 2022-03 packages based on Eclipse 4.23, with certain packages choosing to provide one by default. The Installer now also includes a JRE--consider using the Installer. Please see 5 Steps to Install Eclipse.
There are several package choices. Note that you can install the features from any package into any other package. If you are, for example, planning to do mostly Java development and some C/C++ development, you should download the Eclipse IDE for Java Developers and then add the C/C++ development tools via the "Help > Install New Software..." menu option.
The download will be delivered as a compressed (i.e. a ".zip", or ".tar.gz") file. Decompress this file into the directory of your choice (e.g. "c:\eclipse" on Windows) and ensure you have full Read and Execute permissions. You can optionally create a shortcut of the executable file ("eclipse.exe" on Windows, or "eclipse" on Linux).
Note that there is a known problem with the built-in decompression utility on all current versions of Windows. We recommend that you use a more robust decompression utility such as the open source 7zip when decompressing an Eclipse download. Some people report success when initially decompressing Eclipse into a root directory (e.g. c:\) and then moving it to a more appropriate home (e.g. c:\Program Files\Eclipse)
It is strongly recommended to configure Eclipse with the specific JVM that you want. See the instructions at Eclipse.iniThis is a very important step to be sure that Eclipse is using the JVM you intend and can't be influenced by any other software that might alter your system.The JVM used to launch Eclipse has no affect on whether it can compile Java sources for other Java language versions.
Use the Help > Install new software... menu option to add Kepler features to your Eclipse installation (you can, for example, use this option to add C/C++ development support). Additionally, you can tap into a vast collection of extensions provided by the Eclipse community and ecosystem via the Eclipse Marketplace Client (Help > Eclipse Marketplace). Note that not all Eclipse packages contain the Eclipse Marketplace Client.
If you've "installed" Eclipse but are having trouble getting it to run, the most likely cause is that you have not correctly specified the JVM for it to run under. You may need to edit the eclipse.ini file.
Another common mistake on Microsoft Windows is a mismatch between the "bittedness" of Eclipse and the JVM/JDK. This is the most frequent cause of an Error 13. 64-bit Eclipse requires a 64-bit JVM, and 32-bit Eclipse requires 32-bit JVM--you can not mix-and-match between 32-bit and 64-bit, so make sure the version of Eclipse you installed matches the JVM/JDK that you're using to run it (and make sure you're using eclipse.ini to specify the exact JVM used to run Eclipse, described above).
As a simple test, open a Command Prompt window, move to the directory that is pointed to by the -vm argument in your eclipse.ini, and run the intended java.exe with the -d32 switch to test if it supports 32-bit, or -d64 to test for 64-bit support. It's often simplest to download a version of Eclipse that will work with whatever Java you already have installed.
On more recent versions of the Mac, if you don't have a full JDK of an appropriately high version installed, the OS produces this bogus message. Installing any JRE will not eliminate this problem. A full JDK needs to be installed on the Mac.
Eclipse downloads are not password protected. This is a known problem with the built-in decompression utility on all current versions of Windows. We recommend that you either download the installer or use a more robust decompression utility such as the open source 7zip when decompressing an Eclipse download. Some people report success when initially decompressing Eclipse into a root directory (e.g. c:\) and then moving it to a more appropriate home (e.g. c:\Program Files\Eclipse)
I have a problem with linking and\or running a simple program in my eclipse. I'll try to first give a full description of the setup I'm using, to help identify the problem. Please notice that this is my first experience with installing and setting up an operating system which is not Windows, though I got to use some version of Ubuntu on my campus.
I created a new Ubuntu virtual machine yesterday on VMware Player. I provided it with the path to an image file of the installation disc of Ubuntu 11.10 for 32 bit systems named "ubuntu-11.10-desktop-i386.iso".
First, I chose to install all the updates offered to me automatically by Ubuntu (around 400). I let the thing download and install in the background, and when it finished, I restarted (as I was requested).
The bash history than shows a run of "sudo apt-get update", which I remember seemed successful in installing some stuff. Again, the line originated in some tutorial or guide to installing Java on Ubuntu.
I than went on to install the Java version 6 JRE using "sudo apt-get install sun-java6-jdk sun-java6-plugin". This worked and made me happy (as a latter "java -version" showed that Java was installed) - finally, the correct command was found!
As cqcallaw recommended in his second comment, installing using sudo apt-get install eclipse instead of manually downloading and unpacking the compressed package, solved the weird behaviour eclipse exhibited.
Assuming you are using a 64 Bit version of Windows, choose Windows 64 Bit next to Eclipse IDE for Java EE Developers. I like this edition because it seems to come with the most complete set of tools pre build in.
On the next screen you will be presented with the different download options. First, have a lawyer read the Oracle Binary Code License Agreement for Java SE thoroughly and click Accept License Agreement if you agree to the terms. Then choose the Windows x64 version if you have 64 bit, or Windows x86 if you have a 32 bit version.
Once the installer is downloaded, navigate to your downloads folder and double click on the downloaded file jdk-8u45-windows-x64 (Note: the version might be different depending on when you downloaded it).
Hey there,
I have installed Juno Eclipse in Windows 10 and install the plugin TestNG, but not shown in any place where it should be, however I have performed the same steps to view or run a test with this and not displayed.
But I want to add an issue.I have another system having linux mint 18. I have been trying to install eclipse on it for 3 days. but i was unlucky every time.
After final step when i run eclipse application It gives a big error.Please give a solution.
I have installed luna on my windows10 machine, after creating a java class the editor is opening/malfuncting so I am able to write/read the code on editor. Updated my java version is also installed on my machine.
