Eclipse - How to fix No Java Virtual Machine was found Error

Are you getting below eclipse startup error?

A Java Runtime Environment (JRE) or Java Development Kit (JDK) must be available in order to run Eclipse.

No Java virtual machine was found after searching the following locations: /Library/Java/JavaVirtualMachines/jdk1.9.0_1.jdk/Contents/Home/bin

Well, today I found the same error while starting up Eclipse locally on my Mac. I have been using Eclipse since last 10 years and never faced this error before.

I immediately correlated this error with the some JRE and JDK un-installation did last week 🙂

Basically, over time I had installed Java 8, Java 9 and Java 10. When I went to folder /Library/Java/JavaVirtualMachines I saw total 3 folders with respective JDK setup for Java 8, 9 and 10.

In order to avoid conflict I have decided to remove old Java versions 8 and java 9. I did it by simply deleting 2 folders.

As my Eclipse’s eclipse.ini file had Java 9 by default as a VM. It failed to startup with above error message.

How to find eclipse.ini file?

  • Right click on Eclipse.app icon
  • Click on Show Package Contents
  • Go to folder /Contents/Eclipse/
  • You will find eclipse.ini file
eclipse.ini file

How to fix Eclipse Startup Error?

You have open eclipse.ini file and change -vm path to correct JDK location.

In my case it’s /Library/Java/JavaVirtualMachines/jdk1.10.001.jdk/Contents/Home/bin.

Now try restarting your eclipse by clicking eclipse.app icon and error should go away. Let me know if you face any issue starting Eclipse application.

Pro Tips:

Keep updating to latest Java version every 6 months. It’s my suggestion to get all latest features of Java and keep updating your project.

Keep updating Java Version to latest
