RE: Maven Book recommendation
I am not sure anything exists, but I would appreciate such a thing also. -Original Message- From: Bruno Melloni Sent: Thursday, January 27, 2022 3:10 PM To: users@maven.apache.org Subject: Maven Book recommendation EXTERNAL It became very clear to me that my current approach of googling tutorials, guides and solutions is a wildly inadequate approach to learn Maven. Mainly because all of those are either far too basic for "real life" projects, or because they assume prior knowledge that I don't yet have. So, I am looking to buy a good book to methodically learn all I need about Maven. Because of how I learn best I would like to find a book that uses the following as its presentation approach: * It must be gradual, starting from the assumption that I know nothing and only learn what is taught in the book. * New concepts must include sample code that I can type and test, either complete code or as an extension to a previous example. Absolutely no "loose snippets" that assume prior knowledge (for example this is what makes most formal Spring documentation completely useless to me, as I often can't follow it to a complete functioning solution, and I had similar but not as severe issues with the formal Apache Maven documentation). * The end of each chapter must have exercises that I can code and run to test my understanding, with the ability to download the solution from a website in those cases when my code fails to function correctly. * Not essential but it would be ideal if the book was available in electronic form and readable through an ebook reader that functions on a Microsoft Surface tablet (Windows 10/11) and remembers the last page I read (even better if position syncs between the tablet and my desktop so that I can continue reading on either). If _you learned Maven from a book that matches at least the first 3 criteria_, please recommend it. I'd greatly appreciate it.
RE: Ambari 2.7.6 build questions
Thanks. You are clearly helpful.
If I may prod you regarding manual download/install of items in .m2
When I originally initiated the project (following ambari docs) and used:
mvn versions:set -DnewVersion=2.7.6.0.0
and again for ambari-metrics
a bunch of things got downloaded. When I ran clean/test/compile builds more
items were downloaded and dropped into my local .m2
What did NOT get downloaded were two items. One of which is
maven-source-plugin. MVNRepository shows (for 3.2.1)
org.apache.maven.plugins
maven-source-plugin
3.2.1
Which matches other org.apache.maven plugins such as shade and surefire and
these WERE downloaded. Is there some reason these missing two were left out?
Importantly, if I go to

Could I just grab the jar, pom and sha1, copy these to my .m2 repo and they
would get picked up by the build?
I notice that the local repo versions of things have extra items such as :
several m2e-lastUpdated and _remote.repositories I understand these may only
be relative to ECLIPSE.

Hi Marc,
The "2.1.4" line should be left out. Clearly the authors are
not following standard practice for managing dependencies, so do not assume
that they know what they're doing.
Change the version in the dependencyManagement section if you need it to be
v2.1.4.

Ambari 2.7.6 build questions
HI all,
I get a ‘overriding managed version 2.0.1 for rpm-maven.plugin’ message and I
see two plugin definitions for this artifact, with two versions, in the same
‘build’ block in the top-level (ambari-2.7.6.0.0) POM. From what I see, does
this mean that the plugin must be declared in both places:

and

In any case, why is the version different for these declarations?

Ambari build
Hi all, This is a stock ambari 2.7.6 build attempt on Ubuntu 18.04. I am not a java entity but I am interested in understanding how these tools operate with a view to getting away from Cloudera. We currently run with CDH 6.3, the free/express version and this leaves us stuck with Centos7, or Ubuntu18, both of which are EOL, or fast approaching. Given the exorbitant pricing per node for ANY version of Cloudera, it is prohibitive to justify the cost when making money off data is not a thing we could possibly contemplate. Aside from the obvious fact that every build produces errors which seem to have been ignored by whoever created this, I am mystified as to why the errors are different depending on how I run a build. I have OpenJDK 8 installed, as well as the general pre-requisites according to the Ambari documentation. Maven 3.6.0 Eclipse 2021-12 (4.22.0) IntelliJ IDEA 2021.3.1 (Community) Below are the output errors from OS CLI, Eclipse and IntelliJ. All three produce DIFFERENT errors and this is confusing as I thought they all used Maven. I run an INSTALL build with rat.skip as RAT seems to produce thousands of licence errors for every item in the project. If RAT is so important, why have these errors not been sorted? Also, if I have -Dskiptests, why do tests still get run? I am sure that there are folk who have successfully built Ambari but useful and successful attempts have not been published for any recent version. Any information would be helpful. Thanks.
