Hi Guixers,
First let me say I'm a Maven novice, so it's possible I'm doing something dumb on the Maven side of things.
I'm unable to make a bare-bones Maven project build in Guix.
This looks to be a problem with mismatched dependencies in Guix around java-commons-codec.
I suggest what probably needs to be fixed upstream below (assuming my hunch is correct!).
However I'm looking for advice on how to workaround this problem today to get a basic Maven package building.
My method:
Following advice here:
Using an environment like so:
guix environment --ad-hoc maven
I create a new git repo and put this in the root (so pom.xml, etc, sit in in the root of the repo)
mvn archetype:generate -DgroupId=com.quantile.app -DartifactId=java-test-repo -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.4 -DinteractiveMode=false
I'm able to package and run everything OK (obviously the dependencies are being pulled from the web in this case):
mvn package
java -cp target/java-test-repo-1.0-SNAPSHOT.jar com.quantile.app.App
Next I try to create a bare-bones Guix package to build this (this time there will be no web access during the build):
(define-public java-test-repo-integration
(let ((commit-integration "b9e3894aa3629fc2d60ceadea2f655d4cb6a826b"))
(package
(name "java-test-repo")
(version integration-version)
(source
(git-checkout
(url "ssh://git@vcs:1234/ea/java-test-repo.git")
(commit commit-integration)))
(build-system maven-build-system)
(home-page "
https://vcs/projects/EA/repos/java-test-repo/browse")
(synopsis "Java Test Repo Production")
(description "Java/Maven bare-bones framework for testing")
(license license-quantile))))
I get the following build failure:

After doing some digging I think I know why:
$ guix show
java-commons-codec
name: java-commons-codec
version: 1.15
outputs: out
systems: x86_64-linux i686-linux
dependencies: apache-commons-parent-pom@50 java-commons-lang3@3.9
java-junit@4.12
So it's packaged with a propagated apache-commons-parent-pom at version 50.
See also here for package definition:
https://github.com/guix-mirror/guix/blob/9fe48723c8266ffe8e6a639be2ec2e362cf20cb5/gnu/packages/java.scm#L7671here
But if I look at the POM in the Gnu Store - it is showing version 52 for the commons-parent which I am assuming (perhaps incorrectly?) should match the version 50 above?
/gnu/store/7qgi821xidn9nbb07qw35g7wmgv84jln-java-commons-codec-1.15/lib/m2/./commons-codec/commons-codec/1.15/commons-codec-1.15.pom
<parent>
<groupId>org.apache.commons</groupId>
<artifactId>commons-parent</artifactId>
<version>52</version>
</parent>
Likewise if I look at the source code on Apache's website - it's 52 too:
<parent>
<groupId>org.apache.commons</groupId>
<artifactId>commons-parent</artifactId>
<version>52</version>
</parent>
What I think has happened is that java-commons-codec has been promoted from version 1.14 to version 1.15 without changing the propoagated input?
On version 1.14 everything would match:
<parent>
<groupId>org.apache.commons</groupId>
<artifactId>commons-parent</artifactId>
<version>50</version>
</parent>
So assuming this isn't going to cause an avalanche of other issues the solution proper seems to be either downgrade java-common-codec to version 1.14, or upgrade the dependency on apache-commons-parent-pom to 52?
What I'm looking for today is any workaround which allows me to use Maven without having to wait to for upstream fix.
My first attempt was to try - adding an inherited package and then swapping this in place of 1.15:
(define-public java-commons-codec-old
(package
(inherit java-commons-codec)
(version "1.14")))
This seems to just go round in circles never building and throwing Java exceptions?
I also tried manually patching the whole dependency tree, but I think I've introduced the same package more than once attempting this as I get symlink errors:
(define-public java-commons-codec-old
(package
(inherit java-commons-codec)
(version "1.14")))
(define-public java-surefire-api-old
(package
(inherit java-surefire-api)
(propagated-inputs
`(("java-commons-codec" ,java-commons-codec-old)
,@(alist-delete "java-commons-codec" (package-propagated-inputs java-surefire-api))))))
(define-public maven-surefire-common-old
(package
(inherit maven-surefire-common)
(propagated-inputs
`(("java-surefire-api" ,java-surefire-api-old)
,@(alist-delete "java-surefire-api" (package-propagated-inputs maven-surefire-common))))))
(define-public maven-surefire-plugin-old
(package
(inherit maven-surefire-plugin)
(propagated-inputs
`(("maven-surefire-common" ,maven-surefire-common-old)
,@(alist-delete "maven-surefire-common" (package-propagated-inputs maven-surefire-plugin))))))
(define-public java-test-repo-integration
(let ((commit-integration "b9e3894aa3629fc2d60ceadea2f655d4cb6a826b"))
(package
(name "java-test-repo")
(version integration-version)
(source
(git-checkout
(url "ssh://git@vcs:1234/ea/java-test-repo.git")
(commit commit-integration)))
(build-system maven-build-system)
(arguments `(#:maven-plugins
(("maven-surefire-plugin" ,maven-surefire-plugin-old)
,@(alist-delete "maven-surefire-plugin" (default-maven-plugins)))))
Any ideas greatfuly received!
