Maven is now part of Guix, yeah! I gave it a try and found some bugs
which I post collectively here. I don't know yet where exactly they
come from and if they are trivial or not to fix. So if you think they
should better go each into a separate bug report, please separate them.

For reference, I'm on Ubuntu with:

$> guix pull --list-generations | tail --lines=6
guile: warning: failed to install locale
warning: failed to install locale: Invalid argument

Generation 2    Jun 22 2018 21:53:40    (current)
  guix 18ab54d
    repository URL: https://git.savannah.gnu.org/git/guix.git
    commit: 18ab54d4a2aaf932b14e69c30650c1d2c4db33c7


1) The following propagated inputs are used from bash scripts
and are missing: which, coreutils

$> guix environment -C --ad-hoc maven icedtea@3:jdk -- mvn 
/gnu/store/sk23y72hma8x6n5ch6xqgql1q93dg7if-profile/bin/mvn: line 46: uname: command not found

/gnu/store/sk23y72hma8x6n5ch6xqgql1q93dg7if-profile/bin/mvn: line 67: dirname: command not found
/gnu/store/sk23y72hma8x6n5ch6xqgql1q93dg7if-profile/bin/mvn: line 94: which: command not found
The JAVA_HOME environment variable is not defined correctly
This environment variable is needed to run this program
NB: JAVA_HOME should point to a JDK not a JRE

2) There is something wrong with the version output:

$> guix environment -C --ad-hoc maven icedtea@3:jdk coreutils which --
mvn -version

null <version unknown>
${distributionShortName} home: /gnu/store/a19m087lz9fg4c2aplvdlm1y2iiibjdb-maven-3.5.3
Java version: 1.8.0_161, vendor: Oracle Corporation
Java home: /gnu/store/7dah2ha88f4sxakpgdlbfn6mvs842j6w-icedtea-3.7.0-jdk/jre
Default locale: en_US, platform encoding: ANSI_X3.4-1968
OS name: "linux", version: "4.4.0-128-generic", arch: "amd64", family: "unix"


Compare this to my "native" Ubuntu maven:

$> /usr/bin/mvn -version
Apache Maven 3.3.9
Maven home: /usr/share/maven
Java version: 1.8.0_161, vendor: Oracle Corporation
Java home: /gnu/store/8yfdmh7hsnfq87ddcyjz5nxk5f208pmc-icedtea-3.7.0-jdk/jre
Default locale: en_US, platform encoding: ANSI_X3.4-1968
OS name: "linux", version: "4.4.0-128-generic", arch: "amd64", family: "unix"


3) The -version part is already handled by Java code. So I tried to
debug Maven remotely from Eclipse, but it failed with a message saying
that debug symbols were missing. I want to verify this again, but could
this be a problem of the ant-build-system removing debug symbols?

4) I cannot use icedteaX (x \in {1,2}) (i.e. X=2 means JDK 1.7) with
Maven. Is this a bug or a fact?

$> guix environment -C --ad-hoc maven icedtea@2:jdk coreutils which --
mvn -version

Version 52.0 means Java 1.8. I think this is because we are now building
all Java packages with ant-build-system with Icedtea@3 and letting it
output Java8 code. Right?

If this is the case anyway, we don't have any chance to choose a JDK to
run maven with (if we choose from Guix, not from other locations).
Should we then add icedtea@3 as a propagated input to maven? Then a
user can directly use Maven and doesn't have to think of installing a
JDK first. Mhm, maybe too strict and too heavy in size?



From now on I'm in a container with a fresh .m2 directory,
assuming "mvn-home" is an empty directory:

guix environment -C -N --share=mvn-home/=/home/bjoern/.m2 --ad-hoc maven coreutils which icedtea@3:jdk


5) Maven complains about the logger output:

$ENV> mvn clean install
[WARNING] The SLF4J binding actually used is not supported by Maven: org.slf4j.impl.SimpleLoggerFactory
[WARNING] Maven supported bindings are:
[INFO] Scanning for projects...
[...]


When looking at the package definition of maven, I find in the inputs:

       ;; TODO: replace with maven-slf4j-provider
       ("java-slf4j-simple" ,java-slf4j-simple)))

Is this comment related to the WARNING? Will it go away with
maven-slf4j-provider?


6) Maven does not compile Java 1.8 code.

To reproduce this, build any Maven project that has either source or
target language version set to 1.8:

<properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>

As our Maven mostly works, you can just use:

$ENV> mvn archetype:generate

to create a new Maven project. Edit the pom.xml to set the versions.

Then [I head some problems with tests, so skipping them here]:

$ENV> mvn clean install -Dmvn.tests.skip=true -X -e

8) BTW maven is NOT creating a reproducible output. That's important if
you want to use it to as a build tool for Guix:

$ENV> jar tvvf
~/.m2/repository/de/xxx/tst2/1.0-SNAPSHOT/tst2-1.0-SNAPSHOT.jar

 110 Fri Jun 22 22:29:26 GMT 2018 META-INF/MANIFEST.MF
   0 Fri Jun 22 22:29:26 GMT 2018 META-INF/



That's it for now.
