- Eclipse Luna For Mac Sierra 2017 10) Once the download is complete, run the file and follow the installation instruction. 11) Once installation is done, open the Eclipse, it should run fine now.
- I downloaded the new Eclipse Luna (ver. 4.4) and changed to Dark Theme, but the code editor is not changing. See the screen-shot: I tried this on MAC, Windows and Linux, always the same result.
If you want to run your own Java code, either for application or software development on Mac, Eclipse IDE or Integrated Development Environment is probably one of the top choices. It is written in Java and generally used for developing Java apps. You can use Eclipse IDE for writing, compiling and running your Java code. Eclipse has the essential tools any Java developer might need, including a Java IDE, a Git client, XML Editor, Maven, and Gradle integration.
Go to the download folder, you would find a file named “eclipse-java-mars-2-macosx-cocoa-x8664.tar” (the file name may be different based on the version you download but it should be a tar file starting with word eclipse). 182,783 DOWNLOADS; A complete set of tools for developers who want to create Eclipse plug-ins, Rich Client Applications or Remote Application Platform (RCP+RAP), plus Mylyn, the m2e Maven integration, and an XML editor. In addition to the CVS Eclipse Team provider, it also contains the EGit tooling for accessing Git version control systems. Eclipse Luna includes official support for Java 8 in the Java development tools, Plug-in Development Tools, Object Teams, Eclipse Communication Framework, Maven integration, Xtext, Xtend, Web Tools Platform, and Memory Analyzer.
Eclipse usually works great with Macs. Developers involved in developing applications for macOS find this universal tool platform a great help. Unfortunately, Eclipse was one of the pieces of software affected by the upgrade to Big Sur. For some reason, Eclipse does not work after Big Sur update and users are getting errors when using the platform. In some cases, Eclipse fails to even launch at all.
Here is an example of the error message the users are getting:
The JVM shared library “/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/../lib/server/libjvm.dylib”
does not contain the JNI_CreateJavaVM symbol.
Or this pop-up:
Alert! Failed to create the java virtual machine
Pro Tip: Scan your Mac for performance issues, junk files, harmful apps, and security threats
that can cause system issues or slow performance.

This issue has a huge impact on the development timeline of applications the developers are working on. And this is just one of the issues that have been plaguing Mac users who upgraded to macOS Big Sur.
Why Eclipse Does Not Launch in Big Sur
Just like other apps that broke down after the Big Sur update, Eclipse does not work well with the new macOS because of compatibility issues. Big Sur came with a lot of changes, not only in terms of UI, but under the hood as well. And one of those changes might be causing the error you’re getting when using Eclipse.
This problem is common when you update your operating system. Something that was working fine is suddenly having trouble running in the new system. At times, the fault lies with the developer who failed or forgot to update the app to make it more compatible with the new OS.
Corrupted files can also be the reason behind this issue. When the files associated with the software get damaged, the performance will be greatly affected. If you have an antivirus, try running a scan to see if malware is the culprit.
No matter what the reason is, fixing this error as soon as possible shouldn’t be that complicated. We’ve listed down the solutions below to help you sort this problem out.
What to Do if Eclipse Does Not Launch in Big Sur
If Eclipse is suddenly not working on Big Sur, here are some of the steps you can take.
Solution #1: Reboot your Mac.
The simplest solution is to restart your Mac. Click the Apple menu > Restart to give your Mac a fresh start. Rebooting usually fixes minor glitches and temporary issues your computer might be experiencing. After restarting, you can try to launch Eclipse again to see if you’ll be successful this time.
Solution #2: Update Eclipse.
An outdated software can cause a wide range of troubles, so you need to check first if there are any pending updates you need to install. And there are two ways to do this. First, go to the Mac App Store and check under the Updates tab if there are available updates. Another way to go around this is to check the manufacturer’s website and see if a new patch or update has been released. Make sure to optimize your Mac first using Outbyte macAries to make sure no corrupted files will prevent the update from installing.
Solution #3: Edit the Eclipse Preferences File.
Some users who were experiencing this error found success by adding a string of script in the plist file. To do this:
- Open a Finder window.
- Click Go > Go to folder.
- Copy and paste the following address: /Applications/Eclipse.app/Contents/Info.plist
- In the file, add the following script: <string>-vm</string><string>/Library/Java/JavaVirtualMachines/jdk1.8.0_201.jdk/Contents/Home/bin/java</string>
- Make sure to replace the <string> value with your own JAVA_HOME.
Close the app and restart your Mac before launching Eclipse again.
Solution #4: Edit the Info.plist and set the -vm value.
Here’s another trick you might want to try:
- Install the latest Eclipse version or update your current version.
- Right-click on Eclipse.app, then click Show Package Contents.
- Open the Info.plist file with a text editor.
- Add -vm/Library/Java/JavaVirtualMachines/jdk1.8.0_191.jdk/Contents/Home/bin/java under the key Eclipse.
- Edit/Java/JavaVirtualMachines depending on what version you have.
- Next, close the file and relaunch Eclipse to see if it worked.
Solution #5: Re-install openJDK VM.
To fix this issue, you can also try deleting the openJDK VM and reinstalling it. To do this:
- Open a Finder window.
- Click Go > Go to folder.
- Copy and paste the following address: /Library/Java/JavaVirtualMachines
- Look for the openJDK folder and drag it to the Trash.
- Reinstall openJDK.
- Open the Applications folder and right-click on Spring suite > Show Package Contents.
- Edit file Contents/info.plist and add this string on Solution #3.
Wrapping Up
Eclipse Ide Download
The above steps should help you resolve this error, but keep in mind that most of these steps were suggested by other Eclipse users as well. Some might work for you while others may not. All you need to do is work your way down the list until you find the solution that works for you.
Install a new version of Eclipse to use with MinGW C++
MinGW means Minimalist GNU for Windows: GNU is a source of open source programming tools (GNU stands for GNU is Not Unix).
Before starting this handout, you should have first downloaded the files needed by MinGW C++. Now you will download a version of Eclipse that is already set up to use MinGW.
You may want to print these instructions before proceeding, so that you can refer to them while downloading and installing MinGW and Eclipse. Or, just keep this document in your browser. You should read each step completely before performing the action that it describes.
Eclipse: Version 4.4 (Luna)
The Eclipse download requires about 200 MB of disk space; keep it on your machine, in case you need to re-install Eclipse. When installed, Eclipse requires an additional 200 MB of disk space.
Downloading Eclipse
- Click Eclipse
The top of the following page will appear in your browser.
In this handout we will download Eclipse Standard 4.4 for Windows 32 Bit (the current version is 4.5 Mars); if your computer uses Windows, continue below; otherwise look for the pull-down list showing Windows and instead choose either Mac OS X (Cocoa) or Linux and then continue below.
It is critical that Java, MinGW, and Eclipse are either all 32 Bit or are all 64 Bit (and only if your Machine/OS supports 64 Bit): I think it easiest to use 32 Bit for everything.
- Click the Windows 32 Bit Operating System for your machine, under the heading Eclipse IDE for C/C++ Developers (the fourth selection from the top).
You will see the following page (don't worry about the name of the institution to the right of the big downward pointing arrow).
- Click the big downward pointing arrow underneath the Download eclipse-cpp-luna-R-win32.zip from: The site named here, in purple to the right of the arrow: [United States] Columbian University (http) is the random one chosen by the download page this time; yours may differ.
This file should start downloading in your standard download folder. This file is about 200 Mb so it might take a while to download fully if you are on a slow internet connection (it took me about 5 minutes over a cable modem). Don't worry about the exact time as long as the download continues to make steady progress. In Chrome progress is shown on the bottom-left of the window, via the icon
The file should appear as
Terminate the window browsing the Eclipse download.
- Move this file to a more permanent location, so that you can install Eclipse (and reinstall it later, if necessary).
- Start the Installing instructions directly below.
Installing Eclipse
- Unzip eclipse-cpp-luna-R-win32.zip from:, the file that you just downloaded and moved.
On my machine (running Windows 7), I can- Right-click the file.
- Hover over the IZArc command from the menu of options.
- Click Extract Here
If you do not have IZArc or an equivalent unzipping program, here is the web site to download a free copy of IZarc.
Unzipping this file creates a folder named eclipseC:Program Files directory.
- Create a shortcut on your desktop to the eclipse.exe file in this eclipse folder:
On most Windows machines, you can- Right-press the file eclipse.exe
- Drag it to the desktop.
- Release the right button.
- Click Create shortcut here
Now you are ready to perform a one-time only setup of Eclipse on your machine.
- Double-click the shortcut to Eclipse that you just created above.
The following splash screen will appear
and then a Workspace Launcher pop-up window will appear.
In the Workspace text box, your login name should appear between C:Users and workspace, instead of Administrator.
Leave unchecked the Use this as the default and do not ask again box. Although you will use this same workspace for the entire quarter (checking projects in and out of it), it is best to see this Workspace Launcher pop-up window each time you start Eclipse, to remind you where your workspace is located.
- Click OK.
Progress bars will appear at the bottom of the spash screen as Eclipse loads.
Eventually the Eclipse workbench will appear with a Welcome tab covering it.
- Terminate (click X on) the Welcome tab.
You will not see the Welcome tab when you start Eclipse after this first time. You should now see the following Eclipse workbench.
Notice the C/C++ words/icon appear on the top left (in the Window title-bar) and below the upper right-hand corner (beneath the tool-bar).
- To simplify the edit/build-recompile/run loop that we will discuss below, perform the following operation: after completing it, clicking Build or Run will automatically save the contents of any edited file before the program is rebuilt and run.
- Select Window | Preferences.
- In the Preferences popup window disclose General and select Workspace.
- Click 'Save automatically before build' checkbox, as follows..
- Click Apply.
- In the Preferences popup window disclose Run/Debug and select Launching.
