If your Mac keeps popping up the error “To use the “java” command-line tool you need to install a JDK”, and you keep thinking that you have installed it, but to no avail, you’re not alone. Here’s what you actually need to do to vanquish this beast.
You may have already searched for answers, finding such varied answers as “delete the cache and cookies on your browser” to “sacrifice a goat to the ghost of Steve Jobs”, but none of these things work (plus the goat doesn’t like it).
The second is to run native Java 6 apps on your Mac. This how-to discusses procedures to uninstall/disable each of those two Java systems on your Mac. “To use the “java”command-line tool you need to install a JDK popup” is a bothersome pop-ups that appears on the browser while surfing. These pop-ups occurs while the browser gets infected with any potentially unwanted program like third party add-ons, rogue flash players and extensions.
First, to understand what is causing the issue, one or more applications (you know…programs, in oldspeak) on your Mac are calling for Java and not finding it (or at least not recognizing it). This most often happens with Macs that have been updated or upgraded to a newer flavour of OS X 10 (usually Yosemite, El Capitan, Sierra, High Sierra, or Mojave; also known as OS X 10.10, 10.11, 10.12, 10.13 and 10.14, respectively) or that came with an OS X 10+ installed.
So, you think (reasonably enough) that the issue must be that your Java install isn’t updated (enough) for the new OS version.
And that’s where you’d be wrong.

Because in reality, what is happening is that the application or applications that are throwing the error are actually looking for an older, legacy version of Java, and not finding it! Specifically, it is looking for the legacy Java 6.
So, to fix the error, you need to download and install Java 6, also known for these purposes as Java for OS X 2015-001.
Fortunately, Apple has made this easy, as they recognize their screw-up in shipping apps that still rely on a deprecated (i.e. discontinued) version of Java.
Also fortunately, installing the older version does not seem to impact any programs relying on the newer version, at least in our experience.
To download this legacy version of Java, to fix the “To use the java command-line tool you need to install a JDK” error, go here:

The problem was in my case that I installed the JRE, which was installed only as Safari Plugin, but not as usable commandline tool. Therefore /usr/libexec/java_home -v * would not find any installed Java.
The solution is to install the JDK, not the JRE.
