I am trying to create my first macro with LibreOffice version 6.1.6.3 on a MacBook Pro running Mac OS X 10.14.5. When I select menu item 'Tools | Macros | Run Macro' I get this popup box: 'LibreOffice requires Oracle's Java Development Kit (JDK) on Mac OS X 10.10 or greater to perform this task. Please install them and restart LibreOffice.' However, the title of the popup box is 'JRE Required'.
The java, javac, etc. Command line tools are sensitive to the value of the JAVAHOME environment variable and will use 1.6 if this variable points to a 1.6 JDK. The tool /usr/libexec/javahome is your friend here. Running /usr/libexec/javahome. Even though Java application versions is set to Java SE 6 in OS X's Java Preference, executing java -version in Terminal also shows java version '1.6.007', Ant still seems to use JDK 1.5 to be using JDK 1.5 as it does not see JDK 1.6 classes when compiling my code. Whatever the case, if you need Java JRE or Java JDK in OS X 10.11 or later, here's how you can install it. To be clear, if you do not need Java, you should not install Java. And if you're not sure whether you need Java or not, that means you probably do not need Java at all, and you can also avoid installing java.
I found a potential answer to this problem in the question 'Mac Java problem when creating a database' but the detailed directions talk about installing the JDK. The error messages I got in the popup implied that I need both the JDK and the JRE.
When I install the JDK will I also get a copy of the JRE? What are the current instructions for installing the needed Oracle libraries if I want to use macros?
Thanks, bobby

When I install the JDK will I also get a copy of the JRE?
Yes. As I understand, Oracle doesn't provide a JRE alone. Sorry, I can't give any other pointer as I don't use Mac.
@gabix There is a JRE for Mac OS X (current versions filename is jre-8u221-macosx-x64.dmg), but LibreOffice can't deal with that.
I meant the current Java, not the old Java 8.
E-bot, why not repost it as an answer?
Since I work with Windows and not with Mac, I only saw it as an additional hint. And the question was already marked as solved. If it still helps, so much the better. Have all your joy in it.
Question or issue on macOS:
I want to install a specific JDK (the latest for example). For this, I went to the JDK download homepage: http://java.sun.com/javase/downloads/index.jsp.
I looked for a Mac version, but I'm a bit surprised to only see downloadable versions for Linux, Windows and Solaris…
Here's the message for Mac:
OK BUT… when I update Java with Mac I have a JRE and not a JDK…
I don't understand why a JDK version doesn't exist that is easily downloadable/installable (like a jar to unzip?) for Mac…
How to solve this problem?
Solution no. 1:
In a comment under @Thilo's answer, @mobibob asked how to set JAVA_HOME in your .bash_profile on a Mac. Answer:
This will dynamically assign to JAVA_HOME the location of the first JDK listed in the 'General' tab of 'Java Preferences' utility.
See Apple Technical Q&A 1170: https://developer.apple.com/library/content/qa/qa1170/_index.html
EDIT:
If you prefer parentheses to backticks for command substitution, this also works:

As the message says, you have to go to Apple, not Sun, for Java on the Mac. As far as I know, Apple JDK 6 is installed by default on Mac OS X 10.6 (Snow Leopard). Maybe you need to install the developer tools from your Mac OS X installation DVD (the dev tools are an optional install from the OS DVD).
See: http://developer.apple.com/java/
NOTE This answer from 16 Oct 2009 is now outdated; you can get the JDK for Mac OS X from the regular JDK download page on Oracle's website now.

I bought a MacBook Pro yesterday (Mac OS X v10.8 (Mountain Lion)) and there is no JDK installed by default…
As well as javac, I also found it didn't have packages such as SVN installed. It turns out you can get everything from the Apple developer page (you will need to register with your AppleID). SVN is part of the 'Command Line Tools' package.
This is what happens on a fresh MacBook:
Hopefully this will help out other newbies like me 😉
Solution no. 5:
Mac comes with the JDK, for more information check:
Solution no. 6:
The explanation is that JDK is a bit specific and does not contain the library tools.jar. For my development, I need this library and Mac's JDK doesn't provide it:

(Cf. http://developer.apple.com/mac/library/documentation/Java/Conceptual/Java14Development/02-JavaDevTools/JavaDevTools.html)
tools.jar does not exist. Classes usually located here are instead included in classes.jar. Scripts that rely on the existence of tools.jar need to be rewritten accordingly.
It sucks!

The easiest way is to use Homebrew.
Install Homebrew and then:
You can list all available versions using the following command:brew cask search java
Solution no. 8:
Compiling with -source 1.5 -target 1.5 (in a JDK 6 environment) will honor only language elements that were in 1.5 and prior. Great. But there were no language changes in 6 anyway. Problem with this approach (on Mac with 1.6) is that using classes that came AFTER 1.5 will still compile because they exist in the rt.jar. So one could run in a 1.5 env and get a class not found exception with no prior warning when compiling. I found this out the hard way with javax.swing.event.RowSorterEvent/Listener. Both entered 'Since 1.6' but are not caught with -source 1.5

If you installed brew, cmd below will be helpful:
brew cask install java
Mac Os Install Jdk
Solution no. 10:
As of Mac OS X v10.6 (Snow Leopard), you can run Java 6 in 32-bit mode on either 32-bit or 64-bit Intel processor equipped Macs.
If you cannot upgrade to Snow Leopard, Soy Latte is a pre-compiled version of Java 6 for Intel 32-bit.
Hope this helps!
