Add build support for macOS

[bahnwaerter]

Build support for macOS was already there but was broken by the commit abbe715. This change reactivates build support for macOS and adds missing macOS platform-related dependencies.

If you want to check the macOS build support for Ultimate on a fresh macOS Ventura platform, you have to install the following required dependencies using the Homebrew package manager:

sudo brew install maven \
                  openjdk@11

Note that installing the package manager itself automatically installs the required command line developer tools (e.g. Git). You do not have to repeat this step here again.

Before starting with a macOS build, the installed Java Development Kit (JDK) has to be enabled with the creation of the following symbolic link:

sudo ln -sfn /usr/local/opt/openjdk@11/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk-11.jdk

Now, everything is prepared to start a fresh build. Therefore, you should clone and checkout the repository with Git as usual. Then change into the following sub-directory to start the build process using maven with the installed JDK in version 11:

cd ultimate/trunk/source/BA_MavenParentUltimate
JAVA_HOME="$(/usr/libexec/java_home -v 11)" mvn clean install -Pmaterialize

If the build process on macOS succeeds, you can then access the produced macOS Java programs under ultimate/trunk/source/BA_SiteRepository/target/products/*/macosx/cocoa/x86_64/Eclipse.app.

Oh this is very nice, thank you!

Now we only need to add macos solvers, extend our README and adapt our build scripts to provide a MacOS release.

Thanks for merging.

You're right. That's missing right now. As soon as I have time, I'll continue the work for a full macOS release. At least you can now build a release manually via maven if required.
