In termux I use a shell script that replaces java, cf. description "workaround for having java in termux" below. It works incredibly well. At its core is the command
proot -R $UBUNTU java "$@"The only limitation is that I would like to mount some more directories that are not included by the -R switch.
I tried to use proot-distro instead of proot with the following command in the "java" script:
proot-distro login ubuntu-20.04 -- java "$@"When I run a simple command like
java --versionthis works, too, however I get error messages when I pass lists of quoted arguments.Here is an example output of a java call that works fine, when I use
proot -R $UBUNTU java "$@":Here is an example error, when I use
proot-distro login ubuntu-20.04 -- java "$@":Here is an example error, when I use proot-distro login ubuntu-20.04 -- java "\"$@\"" (escaped quotes around $@) :
And finally, here is an example error, when I use proot-distro login
ubuntu-20.04 -- java $@(no quotes around $@):workaround for having java in termux
TL;DR
I create an ubuntu proot, where I install the openjdk. Back in termux I create a bash script named "java" which, when called, forwards to the real java within the ubuntu proot by using the proot command.
How
Set up the ubuntu-20.04 proot (more info here):
Within the ubuntu distro install the openjdk:
(I suppose this also works with later versions of the openjdk.)
Return to termux (press Ctrl-D)
Add the following line in ~/.bashrc
export UBUNTU=$PREFIX/var/lib/proot-distro/installed-rootfs/ubuntu-20.04/From the bash or fish prompt you can do this using the following command:
echo "export UBUNTU=\$PREFIX/var/lib/proot-distro/installed-rootfs/ubuntu-20.04/" >> ~/.bashrcRestart the termux session so that .bashrc is executed and the variable $UBUNTU is set.
Create the script file "java" in ~/../usr/bin/ with the following content:
From the fish prompt you can do this using the following command:
(I don't know how to do this from the bash prompt)
For more information about the proot command, check the manual.
Make the script "java" executable:
chmod 777 ../usr/bin/javaYou can now call java with arguments from termux. I suppose you can do the same trick for javac.
I would be happy to hear about your suggestions for improvement.
