How do you use the maven-simian-plugin in Maven2? - maven-2

I'm looking for a Maven2 reporting plugin for Simian and the closest thing to such a reporting I found is this. The problem is, the documentation for it appears to be for Maven 1 instead. Why is a Maven 1 plugin stored in a Maven 2 repository? I suppose that means I can use it... but how to use? The site mentions reporting but if I don't have a src/main/site, does that mean I can't use it? I was kinda hoping for something like mvn simian:simian similar to mvn checkstyle:checkstyle and mvn pmd:pmd. I don't want to generate site just for the reports. Sites take too long to generate when all I want is a quite xml report.

The Simian plugin listed on central is actually for Maven 1 (if you inspect the contents you'll see a project.xml and a plugin.jelly). So that explains why it doesn't work. This is rubbish and should be removed in my opinion.
As far as I can make out there isn't a publically available Maven 2 plugin, this may have something to do with the licence (Simian isn't open source).
As an alternative, have a look at PMD's CPD plugin, it may not be as fully featured as simian but I know it works in a Maven 2 build and detects copypasta pretty well.
To configure PMD, add something like the following to your POM:
<reporting>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-pmd-plugin</artifactId>
<version>2.4</version>
</plugin>
</plugins>
</reporting>

Attaching Build Number for binaries in Maven

I am running maven build and storing files in Artifactory. One issue I am facing is when ever I try a -snapshot version it overwrites the binary in Artifactory. I tried using the Maven build number plugin, but running in to issues.I reffered to this
http://blog.codehangover.com/track-every-build-number-with-maven/
Describing below What I did?
Updated the masterpom.xml with following line.
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>buildnumber-maven-plugin</artifactId>
<version>1.0-beta-3</version>
<executions>
<execution>
<phase>validate</phase>
<goals>
<goal>create</goal>
</goals>
</execution>
</executions>
<configuration>
<doCheck>false</doCheck>
<doUpdate>false</doUpdate>
<format>${version}.{0,number}</format>
<items>
<item>buildNumber</item>
</items>
</configuration>
</plugin>
Now I update the pom of ear and webproject as below
<build>
<finalName>${project.artifactId}-${project.version}.${buildNumber}</finalName>
</build>
When I ran mvn clean install, ear and war got generated but when i checked the war inside the ear I am finding it as some thing like war-1.0-SNAPSHOT-null.war. I believe the war and ear couldn't get the buildNumber parameter. I was able to successfully generate the buildNUmber.property files and was able to increment the number by running the buildnumber:create plugin. Here are my questions
What I am doing wrong here and why the buildNumber parameter is not picked.
Also I want to generate all the binaries including jars in the following format binary-version-Snapshot.${buildNumber}. So Do i need to update pom of each file or any other way to update this?
Also we are using Hudson builds for Continous Integration and we want to separate developers builds with Hudson Build number. How can we achieve this if we don't want to checkin the buildNumber.properties after the Hudson build.
To get unique snapshots use the uniqueVersion flag (see James Lorenzen's Blog). If you use the maven goal deploy:deploy-file the uniqueVersion flag is true by default. At my company we have the following policy. Only "official" snapshots go to the repository. A "official" snapshot is one that was build on our reference system (our Jenkins ci server). We don't need the unique feature for snapshots, since we let Jenkins archive the artifacts. This way we can always go back to a certain version if we would like too by using Jenkins. If the build breaks the snapshot will not be deployed to the repo.
To your 2nd question; my understanding is that you need to update every pom file. But since it is a one time change, it shouldn't be too much of a burden.
I am not completely understanding your 3rd question ("... separate developers builds with Hudson Build number..."). In case you want to add the build number for every build done by Hudson, you have several options.
You can add a string as classifier while deploying. Maven will add that classifier in the filename (artifactID-version-classifier.jar - e.g. my.company.calendar-0.0.1-Snapshot-Hudson.jar). The artifact will be retrieved by adding the classifier to the dependency.
add another parameter to your maven call - outputfilename (${project.build.finalName}, see maven docu)
changing your version string to something like

Maven Checkstyle Plugin - Test XREF

My maven reports are working great, all except Checkstyle and test xref. My test source is still being cross referenced at xref and not the test xref. So, when I click on the xref from within a Checkstyle report, I naturally get an error, the file isn't found. If I click on a source file, it works perfectly.
I tried testXrefLocation in the configuration to no avail. Is this by design, or am I missing a configuration?
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-checkstyle-plugin</artifactId>
<configuration>
<enableRulesSummary>false</enableRulesSummary>
<includeTestSourceDirectory>true</includeTestSourceDirectory>
<configLocation>${project.build.directory}/checkstyle.xml</configLocation>
<testXrefLocation>${project.reporting.outputDirectory}/xref-test</testXrefLocation>
</configuration>
</plugin>
mvn clean install site
In my target directory where all this stuff is generated, I have both xref and xref-test. However, my checkstyle reports for my test source code are still linked to target/xref and not target/xref-test.
Also, FYI, I am using a lot of inheritance to reduce the amount of configuration in a single Maven POM. Therefore, this plugin belongs to a parent pom which declares which plugins I want to use for testing. I have another that says I want to generate javadoc and source in addition to the compiled code.

I actually ended up removing this configuration in favor of using Sonar since it gives me much more information with a nicer UI.

How can I bind the execution of a Maven plugin to a different Maven plugin's execution?

I am using the maven-eclipse-plugin to configure my eclipse workspace with the configure-workspace goal of the plugin.
I need to perform some additional setup within the workspace that standard eclipse plugins do not appear to accomplish. Setup MAVEN_HOME and setup an external build tool for example. I have some corporately built plugins that can perform these tasks. What I would like to do is bind the execution of this plugin to the execution of eclipse:workspace-configure.
I have tried to do this by:
<executions>
<execution>
<goals>
<goal>eclipse:configure-workspace</goal>
</goals>
</execution>
</executions>
But have had no luck. Is this possible?
I am using the maven-eclipse-plugin to configure my eclipse workspace with the configure-workspace goal of the plugin.
The goal eclipse:configure-workspace doesn't do much things, it just adds the classpath variable M2_REPO to Eclipse.
What I would like to do is bind the execution of this plugin to the execution of eclipse:workspace-configure
Not possible, you can only bind a plugin goal to a phase. Your best option is IMO to create an init script that would call the goals sequentially.
You can't bind an maven plugin to an other. You can configure to run one plugin after an other. For example to run the eclipse plugin first and you coperate after that. You need to define them directly within the same phase. On the other hand the example you give can't really work cause you're trying to bind a goal which with the plugin name. You have to use the configure-workspace only in the goal.

using maven to manage java dependencies in a jruby rails app

I'm trying to write a pom.xml that will allow me to run a command locally and fetch all dependencies that my jruby Rails app has. I'm seeing two different configs though and I'm not totally sure which to use (as I'm not a java person whatsoever)
First, many Pom's i'm seeing just have a tag under the root of the pom.xml that list all dependencies. This doesn't however have any information about where these are stored etc... so I feel like this isn't what I want (I need to copy them to my rails lib dir)
Second option, I'm seeing in the mvn docs is to use the maven-dependency-plugin, which seems more like what i'm looking for. I assume then that my outputDirectory would be something like lib
So I don't fully understand what the purpose of the first option's dependency list is for. All I want is mvn to copy my jars locally (and then eventually when my CI server does a deploy). Can someone point me in the right direction?
First Option
<project>
<dependencies>
<dependency>
<groupId>commons-lang</groupId>
<artifactId>commons-lang</artifactId>
<version>2.4</version>
</dependency>
</project>
Second Option
<project>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<configuration>
<artifactItems>
<artifactItem>
<groupId>[ groupId ]</groupId>
<artifactId>[ artifactId ]</artifactId>
<version>[ version ]</version>
<type>[ packaging ]</type>
<classifier> [classifier - optional] </classifier>
<overWrite>[ true or false ]</overWrite>
<outputDirectory>[ output directory ]</outputDirectory>
<destFileName>[ filename ]</destFileName>
</artifactItem>
</artifactItems>
<!-- other configurations here -->
</configuration>
</plugin>
</plugins>
</build>
</project>
First, many Pom's i'm seeing just have a tag under the root of the pom.xml that list all dependencies. This doesn't however have any information about where these are stored etc... so I feel like this isn't what I want (I need to copy them to my rails lib dir)
This is the traditional way to declare and use dependencies on a Java project. Dependencies declared under the <dependencies> element are downloaded from a "remote repository" and installed to your "local repository" (in ~/.m2/repository by default) and artifacts are then handled from there. Maven projects (at least the Java ones) don't use a local lib/ folder for their dependencies.
Second option, I'm seeing in the mvn docs is to use the maven-dependency-plugin, which seems more like what i'm looking for. I assume then that my outputDirectory would be something like lib
The maven dependency plugin allows to interact with artifacts and to copy/unpack them from the local or remote repositories to a specified location. So it can be used to get some dependencies and copy them in lets say a lib/ directory indeed. Actually, it has several goals allowing to do this:
dependency:copy takes a list of artifacts defined in the plugin
configuration section and copies them
to a specified location, renaming them
or stripping the version if desired.
This goal can resolve the artifacts
from remote repositories if they don't
exist in local.
dependency:copy-dependencies takes the list of project direct
dependencies and optionally transitive
dependencies and copies them to a
specified location, stripping the
version if desired. This goal can also
be run from the command line.
The first goal would use the setup you described in your second option. The second goal would use the standard project dependencies that you described in your first option. Both approaches would work.
The problem here is that I don't know exactly what a JRuby Rails app is, what the development workflow is, how to build such an app, etc so I don't know exactly what you need to do and, consequently, what would be the best way to implement that with Maven.
So I googled a bit and found this post that shows another approach based on OS commands (using the maven exec plugin) and has a complete pom.xml doing some other things. Maybe you should look at it and use it as a starting point instead of reinventing everything. This is my suggestion actually.

Creating documentation with maven

I'm just in the middle of revisiting maven. Our team had a bad experience when we last looked at this, as it was during the period when maven was rearchitecting from 1.x to 2.x, so a lot of the dependencies we needed hadn't been moved across to the new repositories. However, I have the time to reconsider now.
I am interested in using maven and either LaTeX or DocBook for creating documentation, and I was wondering if anyone had any experiences to share, project/module structure, good plugins to use, etc...
Many thanks :-)
Edit:
Just to clarify, I was looking to write a technical article/book, and my desired artifact would probably be a PDF.
DocBook is one of the many supported inputs to Doxia, the engine used to generate docs by maven. Refer here: http://maven.apache.org/doxia/modules/index.html
In fact, the Doxia site answers your exact question: http://maven.apache.org/doxia/book/index.html
You can easily create a site (that contains documentation) with Maven using the mvn site command (i.e. using the plugin site).
This plugin creates technical reports (such as Javadoc, Unit tests reports, code coverage...) but can be also used to create a "real site".
You have more details about that in this page.
Basically, you write your page using APT (Almost Plain Text which is quite simple to understand), or a XML-based format, Xdoc.
2 years ago, I create a complete user guide for one application I developed, using the XDoc format and the Site Maven plugin. Globally, it was quite easy to create!
I hope this will help you!
I've been using with success the Maven plugin Docbkx. You should give it a try
Docbkx
You should definitely take a look at the Maven Docbkx Plugin. It probably fits your needs. Doxia's support of DocBook is -uhm- suboptimal. In fact, last time I tried it, it generated something new that - as far as I could tell - wasn't DocBook.
The Maven Docbkx Plugin that I'm referring to supports all the customizations of the world (through plugin parameters, or XSLT overrides, if you're into that) + it features some mechanisms to integrate it with the Maven build. (Such as processing instructions for including Maven pom properties into your documents.)
Note that the ambition is to have a plugin that prevents you from having to manually put together a processing chain yourselves. So this plugin will both do the transformation to FO, and transforming that to PDF.
I recently implemented the project documentation for my maven multi-module project using docbook and the docbkx plugin for maven. I now have it automatically generating html and pdf files every time I build the project site. I think docbkx really rocks, so I would suggest you use that.
Its true -you can create a very nice site just using the maven site and doxia plugins. In fact I'm using those two to generate my project site, But doxia support for docbook is very limited and doesn't let you modularize documentation, including parts of documents in a main document, for instance. So for the big reference-manuals I'm using docbkx.
If you want to take a peek, my project is here. You can actually download the source and see the nitty gritty of it. And, of course, if you have any question regarding this setup, i'll be more than glad to help.
Cheers

Although the question is quite old I want to give an update on this. If you want to use LaTeX for your documentation you should use a maven plugin to generate the documentation. There are a couple of maven-plugins doing this but a lot of them are not maintained anymore.
There is a new maven-plugin which requires none or less configuration to get it working and the generated PDF (or PS or DVI) can be published as artifact.
Have a look at: mathan-latex-maven-plugin
There is AFAIK no official or semi-official plugin that will process LaTeX or DocBook, but what you could do (besides using the aforementioned site plugin) is to configure the exec plugin to process your LaTeX/DocBook sources during the site lifecycle, i.e. at the same time that the project's website is built.
E.g., something like
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<executions>
<execution>
<id>latex</id>
<goals>
<goal>exec</goal>
</goals>
<phase>site</phase>
<configuration>
...
</configuration>
</execution>
</executions>
</plugin>
