macOS High Sierra installation - hitting roadblock [message #1779379]

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.

I've still Eclipse 4.7 and want to upgrade to Eclipse 4.11 asap. I already tried multiple downloads ( always with the same result) of Java and Eclipse and multiple restarts. The Java installer seems to "install" Java but I simply can't find the file path to it. What else should I check? Perhaps, the issue may be with the Java SE Development Kit?

I'm confused by your problem description. You used the installer and that worked? But you didn't pay attention to the location to which you installed it so afterwards you can't find it? The installer won't run because you don't have the required version of Java? You've installed an actual Java 8 JDK (not a JRE) and something (the installer?) still doesn't work?

It must be sounding odd enough, but yeah, I've installed Java 8 JRE... I'm not a digital guy, and everything seems too complicated to me..

You really didn't answer any of my questions and note that I explicitly said install a JDK, not a JRE, and now you tell me you've installed a JRE. Hmmm, what can I say. Note also, you need to move/copy the application from the mounted DMG in order to run it, but it's totally unclear how far you got or what exactly is failing.

Yeah, it sounds really strange, you would better just to do exactly like Ed Merks have advised.

Totally agree with you.
