Install Java JDK on Mac OSX from dmg/pkg without admin/root

· One min read

Oracle no longer provides compressed versions of JDK 😡 and require root to install (probably they also install an auto updater nagging you all the time)

Download .dmg from Oracle and put in a directory

cd directory-with-dmg

7z x jdk-8u181-macosx-x64.dmg

(alternatively, if you don't have 7zip mount dmg and copy out .pkg)

pkgutil --expand "JDK 8 Update 181/JDK 8 Update 181.pkg" jdk-pkg-unpacked

tar xvf jdk-pkg-unpacked/jdk180181.pkg/Payload

Contents/Home is now the JDK root

mv Contents/Home ~/jdk180181

Now you can put JAVA_HOME="$HOME/jdk180181" and PATH="$PATH:$JAVA_HOME/bin" and start using it
