On macOS and Windows their various builds are also available over the Homebrew and Scoop package managers:<p><a href="https://github.com/AdoptOpenJDK/homebrew-openjdk" rel="nofollow">https://github.com/AdoptOpenJDK/homebrew-openjdk</a><p><a href="https://github.com/lukesampson/scoop/wiki/Java" rel="nofollow">https://github.com/lukesampson/scoop/wiki/Java</a>
You don't need extra projects to manage this stuff anymore.<p>There is a great answer here... <a href="https://stackoverflow.com/questions/52524112/how-do-i-install-java-on-mac-osx-allowing-version-switching" rel="nofollow">https://stackoverflow.com/questions/52524112/how-do-i-instal...</a><p><pre><code> brew install java (12)
brew install java11
</code></pre>
And you can simplify things...<p>In your .bashrc:<p><pre><code> export JDK_HOME=`/usr/libexec/java_home -v 12` # v9+ change to the version you installed
export JAVA_PATH=$JDK_HOME
export JAVA_HOME=$JDK_HOME
export PATH="."
export PATH="${PATH}:${JAVA_HOME}/bin"</code></pre>
RedHat also provides OpenJDK builds for free, although hidden behind a developer account registration.<p><a href="https://developers.redhat.com/products/openjdk/download" rel="nofollow">https://developers.redhat.com/products/openjdk/download</a>
One of the company with large contribution to the AdoptOpenJDK is jClarity. jClarity got purchased by Microsoft a few days ago. Are we seeing MS more involvement for JDK development from now on? They are pushing it big for .NET platform but the JVM consumption is a huge market opportunity. With MS strategy of going all in in cloud computing, supporting the JVM is a no-brainer to me.
Anyone ever tried the Eclipse OpenJ9 VM? I've never heard of it, but it might be fun to see if there's a difference with my various apps and performance in an IDE.<p>I've just been hearing a lot of fuss about GraalVM, though haven't had time to investigate what's so special about it nor how it might help typical 'enterprise' services and Java apps.
I assume this is mostly for windows? All Linux and I assume Mac has openjdk available in the repos. The openjdk project itself also hosts binaries for *Nix
