Anyone familiar with a way how can I can i write something to the stdout from maven.
For instance i would like to write a line everytime i start a new module.
I would use the Maven AntRun plugin to echo the message and bind it on the validate phase (the first phase) of the default lifecyle in the parent pom:
<project>
...
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.3</version>
<executions>
<execution>
<id>entering-module</id>
<phase>validate</phase>
<configuration>
<tasks>
<echo>Entering module: ${pom.artifactId}</echo>
</tasks>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
</project>
This is just an example of course, the message I'm writing here doesn't really add value to what Maven is already providing/doing.

I have been trying to figure out why yuicompressor-maven-plugin is not executed during "mvn package". I can execute it in an independent task as described in the link below but somehow the plugin does not get called from maven life cycle.
http://davidb.github.com/yuicompressor-maven-plugin/usage_compress.html
and here is the sample pom.xml I use,
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
<!-- yuicompressor-maven-plugin -->
<plugin>

I have read similar posts but could not figure out why it's not bounded to "process-resources". Phase and Goal are explicitly set so not sure why it's not called. Is there a way to debug why yuicompressor-maven-plugin is not called during "mvn package"? I use maven 2.2.1. Perhaps the version of my Maven won't work with the plugin?
thanks for your help,

You simply need to put the running out of the pluginManagement area into the usual plugins area like:
<build>
<plugins>
<plugin>
<groupId>net.alchim31.maven</groupId>
<artifactId>yuicompressor-maven-plugin</artifactId>
<version>1.3.0</version>
....
</plugin>
</plugins>
</build>
In pluginManagement you define only the default for plugin in particular the verison but you really don't bound to real execution. For other plugins etc. this works cause the are alreay defined in the build area of the supoer pom so this give you the opportunity to redefine them via pluginManagement but not with a plugin which never has been part of any build area.
Is it possible to add a task to the pom.xml file that will create a tar.gz / .zip file.
for eample:
<tar type="tar.gz" source="resources/sql" tofile="target/sql.tar.gz"/>
Thanks
Use the maven-assembly-plugin
Create a src/main/assembly/bin.xml as detailed at http://maven.apache.org/plugin-developers/cookbook/generate-assembly.html and http://maven.apache.org/plugins/maven-assembly-plugin/descriptor-refs.html#bin
Put your resources sql files in the includes and give the format of output as tar.gz
Next, in your pom.xml put the reference to this plugin
<project>
[...]
<build>
[...]
<plugins>
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.2-beta-5</version>
<configuration>
<descriptors>
<descriptor>src/main/assembly/bin.xml</descriptor>
</descriptors>
</configuration>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</phase>
</execution>
</executions>
</plugin>
</plugins>
</build>
</project>
http://maven.apache.org/plugins/maven-assembly-plugin/usage.html
Last, call this using
mvn package
I'm trying to execute with Maven some test written using Ant tasks. I generated the files required to import the task into Maven, but I can't execute them.
My POM is defined this way:
<build>
<plugins>
<plugin>
<artifactId>maven-ant-plugin</artifactId>
<version>2.1</version>
<executions>
<execution>
<phase>generate-sources</phase>
<configuration>
<tasks>
<echo message="Hello, maven"/>
</tasks>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
I try to execute that message, but I get an error with run:
[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------
[INFO] 'run' was specified in an execution, but not found in the plugin
But, if I run: "mvn antrun:run", I know that this can not run the task.
An if I've different targets, how do I call them from Maven? I've the pom.xml, and build.xml with the ant tasks.
Thanks.

To run Ant tasks from within Maven 2, you need to use the Maven AntRun Plugin:
<build>
<plugins>
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.3</version>
<executions>
<execution>
<phase>generate-sources</phase>
<configuration>
<tasks>
<echo message="Hello, maven"/>
</tasks>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
The Maven Ant Plugin is something else, it is used to generate build files for Ant from the POM.
Try this one..This will be on the validate phase.
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.1</version>
<executions>
<execution>
<phase>validate</phase>
<goals>
<goal>run</goal>
</goals>
<configuration>
<tasks>
<echo message="Hello world" />
<echo message="${env.M2_HOME}" ></echo>
</tasks>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
I have a Maven build with three modules.
Module A exports a jar.
Module B depends on A and exports a jar.
Module C is a set of regression tests that depend on A and B.
The reason the regression tests aren't just part of module B is that they should be able to run against multiple versions of A and B to ensure backwards compatibility. I want to be able to run deploy from the top level build to create A.jar and B.jar, but not C.jar. Is this possible?
<properties>
<maven.deploy.skip>true</maven.deploy.skip>
</properties>
If you don't need to create a JAR at all, you might want to add two more properties:
<jar.skipIfEmpty>true</jar.skipIfEmpty>
<maven.install.skip>true</maven.install.skip>
Note that you still need maven.deploy.skip, otherwise the build will fail during deployment.
The maven deploy plugin includes a skip options that prevents artifact deployment.
<plugin>
<artifactId>maven-deploy-plugin</artifactId>
<configuration>
<skip>true</skip>
</configuration>
</plugin>
You can try adding that to project C.
Use below for module C:
<packaging>pom</packaging>
Use a packaging of type pom for C and rebind all required plugins:
<project>
...
<packaging>pom</packaging>
...

I've some test resources (that are specific for a particular task) zipped in /test/resources/my.zip.
I want to extract the zip content to /target during the maven Test Phase.
Do you know what should I specify in the pom.xml to achieve this?
One solution is to use the maven-antrun-plugin to run the unzip Ant task. The following configuration in the build section of your POM should be pretty much what you need (but I haven't tested it):
<build>
<plugins>
<!-- ... -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<phase>process-test-resources</phase>
<goals>
<goal>run</goal>
</goals>
<configuration>
<tasks>
<unzip src="test/resources/my.zip" dest="target/" overwrite="true"/>
</tasks>
</configuration>
</execution>
</executions>
</plugin>
<!-- ... -->
</plugins>
</build>
