Trying Maven v4

[John Patrick <nh...@gmail.com>]

Hi,
If I want to start testing maven v4.x is it the master branch or the mvn4
branch I need to build?
Or is there a guide I can look at with current/known issues or work arounds?

I've a few issues/features I would like to raise and see if I can do
patches for, mostly more profile options like for;
settings.xml profile support for servers and mirrors.
extensions.xml profile support for extensions.
profile activation based upon other profiles being active or disabled.

i.e. the com.soebes.maven.extensions:maven-buildtime-profiler is good to
look into high build times, but for day to day usage I don't want every
developer or cicd build with the extra overhead or verbose output. Just
want it on release builds or when a developer enables a specific profile.

Someone with a home office nexus so has a <mirrorOf>*</mirrorOf> to their
own proxy, then whilst at a conference want to build they need to change
their default settings.xml to remove that mirror. I've 4 settings.xml
depending if home, travelling, in office or building from a maven staging
repo like maven-1731 (for surefire v3.0.0-M6).

All things just seam simpler switching different profiles.

Cheers,
John

Official answer: you could build Maven 4 yourself - get the code from 
GitHub [1] or GitBox [2] and run mvn package.

Unofficial answer: you can find pre-built packages on Jenkins [3].

Even less official answer: I've published a Homebrew tap [4] that 
automates the Jenkins approach for you, and I know Martin has published 
a Chocolatey package [5] that does a similar thing. Both fetch the 
latest successful build from Jenkins and install it. I've been using the 
Homebrew tap for over a year now, and I haven't had any significant 
problems. It installs nicely along an existing Maven installation. In my 
case, the Maven 4 snapshot is the default, but using a shell aliases I 
can easily use Maven 3.8.5 instead:

    alias mvn3="/usr/local/Cellar/maven/3.8.5/bin/mvn"
    alias mvn4="mvn"


Hope this helps,


Maarten

AFAIK, maven 4 is just a prototype.
