Replacement for my old gist.
Downloads JDKs from AdoptOpenJDK into <cache dir>/jpre/jdks
, then sets a symlink to the currently active JDK.
The symlinks are per-TTY (which usually implies per-shell), and stored in the Rust-std-determined temporary folder,
which is usually $TMPDIR
or /tmp
.
Run cargo install jpre
to get the jpre
binary, and set your JAVA_HOME
to $(jpre java-home)
.
For most people adding this is enough:
export JAVA_HOME="$(jpre java-home)"
This path will be symlinked to the currently selected JDK.
