Hi all, I'm trying to get up and running with Eclipse under macOS 10.13.1 / High Sierra and I'm getting the complete runaround with the Java part.

I first got the message "To open 'Eclipse" you need to install the legacy Java SE 6 runtime." I clicked "More info...", which took me to the Oracle legacy Java SE 6 download website, and I installed the software I downloaded from there.

Next I got the message "Version 1.6.0_65 of the JVM is not suitable for this product. Version 1.8 or greater is required." I've hunted around a bit but I have had no success finding this and in fact I have no idea if I'd even recognize it if I found it, since I have very little knowledge of Java. Among other things, I don't know how to determine which version of JRE is running on my computer. I tried just downloading and installing Java 8 (specifically, jre-8u151-macosx-x64.dmg), but this didn't change anything.

Can anyone help?

A separate question: I'm trying to get set up with the IDE for C/C++ development. A colleague recommended Oxygen. I'm not sure if I'm even trying to install the right package. I've downloaded and installed both eclipse-cpp-oxygen-2-macosx-cocoa-x86_64.dmg and eclipse-inst-mac64.tar.gz, but with both, I don't get beyond the Java version issue. Can anyone guide me here?

P.S. I can't resist grumbling a bit: If Eclipse is based on an unsupported legacy runtime, shouldn't that just be included as part of the installation?

Best regards,
Matt

Nitin, thanks. Do you know whether I need to take any steps to eliminate the legacy runtime first, and if so, can you describe the steps?

I do not know, but I've only generally deleted the files from disk. /usr/libexec/java_home will be able to tell you where that is.
