Cannot find javac

Hello community,

I'm unable to find javac on my system after installing openjdk-21. What am I missing? My understanding is that openjdk includes both the JVM and the JDK and that they are called by the commands java and javac respectively in the terminal. Or am I misunderstanding? Haven't read all the relevant documentation available, because I have trouble finding the relevant information.

archlinux-java status returns the following:
Available Java environments:
java-21-openjdk (default)

My $PATH variable includes the following:
/usr/lib/jvm/default/bin
/usr/lib/jvm/java-21-openjdk/bin/ (added manually)

Full $PATH (messy)
/usr/lib/jvm/java-21-openjdk/bin/:/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/lib/jvm/default/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl:/home/ju/.local/bin:/home/ju/.local/bin:/home/ju/.local/bin

I have tried running archlinux-java fix. I have not yet tried using a different openjdk.

Many thanks

Archlinux has 3 packages for every java version it supports, a java runtime for headless systems, a runtime for all systems AND a development kit .

javac is in the development kit and you probably installed the runtime .

See https://wiki.archlinux.org/title/Java#OpenJDK for details

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky
