Right now I do not have eclipse on my mac. The version of my mac is macos mojave version 10.14.6. I tried to download Eclipse IDE 2018-12 R Packages. It is for Enterprise Java Developers, and the link is here. https://www.eclipse.org/downloads/packages/release/2018-12/r After i installed. I launched it and I got This is the error message I got So i tried this "1. Open the eclipse.ini file from your eclipse folder,see the picture below.

eclipse.ini

  1. Open eclipse.ini in Notepad or any other text-editor application, Find the line -Xmx256m (or -Xmx1024m). Now change the default value 256m (or 1024m) to 512m. You also need to give the exact java installed version (1.6 or 1.7 or other).

max size

Like This:

-Xmx512m -Dosgi.requiredJavaVersion=1.6 OR

-Xmx512m -Dosgi.requiredJavaVersion=1.7 OR

-Xmx512m -Dosgi.requiredJavaVersion=1.8 Then it works well for me. " Eclipse error: 'Failed to create the Java Virtual Machine' I cannot edit this file because it says I do not have access permission. How do I fix that?

Don't put it under /Applications, put it somewhere under your home directory where there won't be permission problems. You shouldn't need to edit the eclipse.ini file, either (it's already set to -Xmx2048m in the current release), but you do need to install a JDK, like one from https://adoptopenjdk.net --preferably version 8 or 11.

BTW, the current version is 2020-06. Unless you have a reason to use an older release, use the current one.

  • I put it in the same folder as eclipse-jee-2018-12-R-macosx-cocoa-x86_64.dmg. I installed what you suggested. Then drag eclipse icon to that folder and then double click it, then same error happens. – BurtCruise Jul 18 '20 at 12:34
  • To get the basics out of the way, *do* you have a JDK installed? And `-Xmx512m -Dosgi.requiredJavaVersion=1.8` are on separate lines as they were originally, right? – nitind Jul 18 '20 at 14:37
  • No. There is no such line as -Xmx512m - Dosgi.requiredJavaVersion=1.8 – BurtCruise Jul 18 '20 at 15:27
