maven Return code is: 409, ReasonPhrase: Conflict - maven

I have problem to deploy my multi-module python project with following structure
parent pom.xml # common pom for others project
project/
pom.xml # project pom
common_features/
sub-project-1/pom.xml # sub project 1 pom
sub-project-2/pom.xml # sub project 2 pom
For deployment I use maven
Settings.xml
General maven setting use for build
<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

parent pom.xml
In this case we have the same URL for SNAPSHOT and RELEASE repository

Now I am not sure what is wrong and I spend a lot of hours of investigation this issue but nothing found. Please do you have some suggestions what is wrong here? Thanks a lot

I found where is the problem. Within parent pom.xml there was the following plugin which change artifactId. I do not know why I got error 409 but finally this was a reason:

Deploying Ant-generated jar to Nexus using maven-deploy-plugin

I have a multi-module project with war and ear module. In war's pom I'm generating jar using maven-antrun-plugin. Now I'm trying to deploy that jar to my Nexus using maven-deploy-plugin.
Here's my war's pom.xml:

When I run clean deploy on parent pom, I'm getting the following error:
Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy (default-deploy) on project test: Deployment failed: repository element was not specified in the POM inside distributionManagement element or in -DaltDeploymentRepository=id::layout::url parameter -> [Help 1]
Ok, so I've added distributionManagement section in war's pom, but I'm getting the same error. If I run the same command on war module, there's no error, but there's also war file deployed on Nexus next to jar file.
Is there a way to deploy just jar file using deploy command?

How to share a filtered resource at generate-sources phase in a multi module project?

I have a parent project with 3 child projects:
parent
project-1
/src/main/resources/config.xml
project-2
/src/main/resources/config.xml
project-3
/src/main/resources/config.xml
The configuration config.xml is used during the generate-sources phase. For the three projects, the config.xml is exactly the same. However, the usage of this config.xml is different for each project.
In project-X, I am referring to config.xml as following:
<build>
<plugins>
<plugin>
<groupId>some-group</groupId>
<artifactId>some-artifact</artifactId>
<executions>
<execution>
<goals>
<goal>some-goal</goal>
</goals>
<configuration>
<input>src/main/resources/config.xml</input>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
What is the best way to share this common config.xml between all 3 projects?
You can use the build-helper-maven-plugin here.

</project>
Now, let's build the project:
D:\workspaces> cd shared-resources-project
D:\workspaces\java\shared-resources-project> mvn clean install
Some notes:
The build-helper-maven-plugin will add the common config.xml file as a resource to Project-X.
Then the Maven resources plugin (MRP) will copy config.xml to the project output directory (target directory by default). During the copy, MRP will also replace ${custom-value} with the specific value provided by Project-X.
The final config.xml will be available to another plugin as long as the other plugin is bound to the generate-source phase AND its declaration appears AFTER the build-helper-maven-plugin declaration. Maven (3.0.4+ at least) calls the plugins in their order of apparition in the pom.xml.

Artifact has not been packaged yet - maven-dependency-plugin

When I build a multi module maven project(using mvn clean compile) where one dependency(part of the build reactor) is copied into another using dependency:copy, then maven complains with the below error.
Artifact has not been packaged yet. When used on reactor artifact, copy should be executed after packaging: see MDEP-187 is thrown
This is perfectly fine, Maven can't copy the dependent jar because it has not been packaged yet and the dependency has to be resolved from the local project and not from the repository.
Lets say project A is being copied into project B using the dependency:copy goal.
Now if I import the projects into eclipse,with the lifecycle mapping set in such a way that the maven-jar-plugin is executed on project A(which means that A is packaged), still project B complains with the same error. How can I get rid of this.I can't ignore dependency:copy in the m2e lifecycle as it's a crucial phase in the build.

I need a ProjectB's jar to contain ProjectA's jar in the jars directory(This is required by a custom class-loader part of a home-grown framework)
With m2eclipse, the artifactItems or dependencies will be resolved to the outputDirectory of the corresponding workspace project if the Resolve dependencies from workspace Projects setting is turned on. This is the root cause for the error in my question.
I ended up forking the existing m2e configurator for this plugin so that it can fetch these dependencies/artifactItems from the respository instead of picking it from the workspace project's outputDirectories .
Though this works with few tests which I had done, it is pretty much a work in progress and in case someone wants to help or contribute, the GitHub URL is

Sonar with multi-module maven project and profiles

I have a main project pom.xml which has one module not bound to any profile (module A) and one module bound to profile rest (module module.REST). In jenkins profile, there is a build configuration with a cobertura and sonar plugin.
When Jenkins executes the sonar build, the maven runner only analyses modules which are not bound to profiles and the project module itself. Is there any other way to tell sonar to analyze all modules without specifying those modules again in the profile where the plugin itself is located (in my case this is jenkins profile)? I think cobertura plugin does perform code coverage on ALL modules.

maven: how to export packed sources with jar in "package" stage

I have a maven export script (that wasn't been written by me) and I would like to add sources coping as well.
the build script generates 2 outputs using the "maven-source-plugin":
.jar and -sources.jar and they are both exist in the same output folder one next to another.
so far only the jar is being copied, I want the script to place the -sources.jar file next to its jar file

thank you in advance!
From looking at MNG-1994 it seems that in each phase a child's plugins will execute before the parent's.
Your parent POM specifies the source plugin (which generates the sources JAR) in the package phase (this is the source plugin's default phase if not explicitly specified in the execution), but the assembly plugin, which generates the tar.gz, zip and uncompressed finished versions of your project, is run before the source plugin because the assembly plugin is declared in the child and the source plugin is declared in the parent.
A solution can be to change the phase the source plugin runs in to ensure it runs before the assembly plugin, something right before the package phase such as prepare-package will work. (full list of lifecycle phases is here)
In the parent, explicitly setting the phase to prepare-package will make it:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-source-plugin</artifactId>
<version>2.2</version>
<executions>
<execution>
<id>attach-sources</id>
<phase>prepare-package</phase>
<goals>
<goal>jar</goal>
</goals>
</execution>
</executions>
</plugin>
This should force the source plugin to execute before the assembly plugin and therefore the assembly plugin should pick up both attached JARs now.
Add another include element with the classifier sources:
<include>org.mytest:*:jar:sources</include>
See the documentation: http://maven.apache.org/plugins/maven-assembly-plugin/assembly.html#class_dependencySet
