Missing aar file in maven2 multi-project build - maven-2

I'm trying to use maven2 to build an axis2 project. My project is configured as a parent project with AAR, WAR, and EAR modules. When I run the parent project's package goal, the console shows a successful build and all of the files are created. However the AAR file generated by AAR project is not included in the generated WAR project. The AAR project is listed as a dependency of WAR project. When I explicitly run the WAR's package goal, the AAR file is then included in the WAR file.
Why would the parent's package goal not include the necessary dependency while running the child's package goal does?
I'm using the maven-war-plugin v2.1-alpha-2 in my war project.

I was able to get my maven build working correctly by adding the following plugin to the ws-war pom file:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<phase>process-classes</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>
${project.build.directory}/${project.build.finalName}/WEB-INF/services
</outputDirectory>
<includeArtifactIds>
ws-aar

</configuration>
</execution>
</executions>
</plugin>

Have you tried using the "type" element in your dependencies? For example:
<dependency>
<groupId>group-a</groupId>
<artifactId>artifact-b</artifactId>
<version>1.0</version>
<type>aar</type>
</dependency>
Its hard to say for sure what your problem is without seeing your actual pom files.
Update:
What happens if, from the parent project, you run:
mvn clean install
Does "install" have any different behavior than "package" as far as your problem is concerned?
Do you see the .aar file in your local maven repository (~/.m2/repository/com/mycompany/.../)?
As a side note, i've never been very happy with the maven war plugin. I've always ended up using the maven assembly plugin. It just seems to work better and is more consistent. Also, make sure you are using the latest version of maven (2.0.9). I spent half a day fighting a similar problem which was fixed in the latest version.

Run tests from maven zip assembly

I have finally succeeded in getting Maven to zip together a bunch of jars using an assembly file and install it to my local repository. That was difficult enough...
Now my goal is to configure another maven project so that when I do "mvn test", it will pull in that zip, unpack it, and run tests from the jars within that zip file. Does anyone know how to do this?
Here is the POM for the assembly project:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

</goals>
</execution>
</executions>
</plugin>
</plugins>

Here is the POM for the second project. Unfortunately, instead of downloading the zip file for RigFocusOnDataHub, it just fetches the jars for all of RigFocusOnDataHub's dependencies from the local repo.

You would need to:
extract the jars from the zip - this is easy enough with maven-dependency-plugin
cut transitive dependencies so your jars don't end up in the path twice - you can do that at the source with maven-shade-plugin or in the test project itself with dependencies exclusions
add the jars to your test classpath, there are many ways to do that, I would try to use additional parameters in surefire configuration first

How to include automatically xmlbeans generated code into maven jar?

I have a project which uses Apache Xmlbeans for databinding. Currently it is very simple it only has some Schema-Files in src/main/xsd and xsdconfig in src/main/xsdconfig.
I want to include the generated Classes into the generated jar-File. It works if I specify the xmlbeans goal:
"mvn xmlbeans:xmlbeans package" --> Creates a Jar with the xmlbeans classes
But I want to do this within the normal build cycle: "mvn package" --> should create a jar with the xmlbeans classes, but won't.
The pom is the following:
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

I tried to bind it manually to the "generate-sources" (And to the "compile" phase, too) phase, but it does not work.

How can I configure the plugin, so that when I run "mvn package" all the generated classes are packaged into the jar?
Greetings,
lerad
If you configure the plugin under pluginManagement, you still need to declare it under plugins. To simplify, I'm not using the pluginManagement in the pom.xml below:
<project>
...
<dependencies>
...
<dependency>
<groupId>org.apache.xmlbeans</groupId>
<artifactId>xmlbeans</artifactId>
<version>2.4.0</version>
<scope>compile</scope>
</dependency>
</dependencies>
<build>
<plugins>
...
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>xmlbeans-maven-plugin</artifactId>
<version>2.3.3</version>
<executions>
<execution>
<phase>generate-sources</phase>
<goals>
<goal>xmlbeans</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
</project>
With this POM (and some XSD in src/main/xsd which is the default location), running mvn clean package just works (i.e. sources are generated from the XSD, compiled and packaged as part of the build).
Try this.
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>xmlbeans-maven-plugin</artifactId>
<version>2.3.2</version>
<executions>
<execution>
<id />
<phase>generate-sources</phase>

</goals>
</execution>
</executions>

<staleFile>${project.build.directory}/generated-sources/xmlbeans/.staleFlag</staleFile>

<quiet>false</quiet>

Problems with maven output directory

I'm using almost same POM for both my projects, they are on the same workspace but they are not related at all, they are related however because in both I use spring and jboss. Here is the pom :
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<configuration>
<warName>spring-book</warName>
<outputDirectory>${jboss.ome}</outputDirectory>
</configuration>
</plugin>
</plugins>
</build>
</project>
What I want to achieve with this POM is that I want to name my war when built spring-book.war and copy it to Jboss location I specified. Now in my first project this works it does exactly what I requested but in other it does not. I changed springversion and jboss home properties variable but everything remains the same, what can I do ? The project builds and all, everything is working perfectly just I don't want to copy everytime in my jboss dir and previously remove the old war, it takes about 20sec on each source code change its a lot
Problem spotted at this line:
<packaging>jar</packaging>
You're not using the right packaging, it should be:
<packaging>war</packaging>
After this change the war plugin should get called and things should work like in the other project :)
You could leave the output directory at its default, and use a profile instead with the maven jboss plugin. It has a hard-deploy target which copies your artifact to the deploy directory. If it's in a profile, you can activate it when (and only when) you want.
Moreover, with the antrun plugin, you can also delete the old war file before copying over the new one (this is useful when the war filename includes the version, but in your case may not be needed).
<profiles>
<profile>
<id>deploy</id>
<build>
<plugins>
<plugin>

<goals>
<goal>hard-deploy</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
</profile>
</profiles>
You can then activate the profile with
mvn -Pdeploy install

How do I link a plugin execution to a phase in maven without forcing me to specify plugin on command line

I have a simple pom and added an ant-run to the compile but it only executes then when I do the following:
mvn install antrun:run
mvn install -- doesn't process the ant-run
mvn antrun:run -- doesn't process the ant-run
I thought that be linking the plugin to the lifecyce phase that the plugin would be executed when I try to achieve that phase. This is not what is happening.
Am I missing some nuance, do I need to have a profile which enables the plugin?
Thanks for the help (pom below)

You've specified the plugin below the <pluginManagement> section. This means that this configuration will be used if the plugin is also declared directly under build/plugins, for example in a child POM.
To make it work in this instance remove the <pluginManagement> tags so that <plugins> is directly below <build> like this:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
...
</plugin>
</plugins>
</build>
You need to add a phase.
e.g.:
<executions>
<execution>
<id>xml2fastinfoset</id>
<phase>generate-sources</phase>
<goals>
<goal>xml2fastinfoset</goal>
</goals>
</execution>
</executions>

compiling project with jdk1.5 using maven2

i managed to create my project structure using maven2.
but when am compiling my project using mvn install
getting error
generics are not supported in -source 1.3
googled to build my project using jdk1.5 and added build tag

but this is not working.
Any hints?
Add the maven-compiler-plugin to your build:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.0.2</version>
<configuration>
<source>1.5</source>
<target>1.5</target>
</configuration>
</plugin>
</plugins>
</build>
There's an "easier" way to accomplish this, without having to paste the same snippet all over your modules. You can set up a reactor and then you refer to it from all the other modules, like this:
<parent>
<groupId>com.foo.bar</groupId>
<artifactId>reactor</artifactId>
<version>1.0-SNAPSHOT</version>
</parent>
In the pom file of your reactor you have to put this:
<packaging>pom</packaging>
To let maven know that it's not a jar/war, etc.
Hope it helps
