Hi!
I'm trying to build https://github.com/hyperledger/iroha-java manually
with Gradle (tried with Guix but I'm stuck), and I get the following
error:
--8<---------------cut here---------------start------------->8---
Execution failed for task ':client:compileJava'.
Could not find tools.jar.
--8<---------------cut here---------------end--------------->8---
Then it suggests that the Java installation might be wrong.
I tried with icedtea 3.7.0, openjdk 9 and openjdk 12, to no avail.
Are our JDK packages wrong missing some jars?

The "tools.jar" is only in de icedtea:jdk output.
You might also need to set environment variable JAVA_HOME to the Guix profile
root that contains icedtea:jdk.

Thanks, this is probably related!
However
--8<---------------cut here---------------start------------->8---
env JAVA_HOME=/home/ambrevar/.guix-extra-profiles/dev/dev ./gradlew jar
--8<---------------cut here---------------end--------------->8---
fails with the same error.

Uh, I looked through one of my Java-related packages and found this snippet:
----------
;; Set JAVA_HOME to help maven find the JDK.
(setenv "JAVA_HOME" (string-append (assoc-ref inputs "icedtea")
"/jre"))
----------
So perhaps JAVA_HOME needs to point to <profile-root>/jre. (Sorry for the
previous suggestion..)
I'm not sure why I added this snippet though, but perhaps it's worth a try.
Kind regards,

It worked! Thanks a lot!
So what do you think of adding
(native-search-paths (list (search-path-specification
(variable "JAVA_HOME")
(files '("jre")))))
to icedtea-* and openjdk-*?

I'm not sure if JAVA_HOME is only needed to build things (so only for the JDK),
or whether it's also useful for JRE.
I agree that it would be good to set when the JDK variant is installed.

By the way, should JAVA_HOME be a native-search-path set by the JDKs?
