I'm writing a pom file to conditionally checkout or update a subdirectory from git. However, it always does a clean checkout. I'm doing this to wrap CI scripts around existing projects without having to change them.
Here's the code (slightly censored, and with the update ommitted):
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>com.example</groupId>
<artifactId>standard-php-project</artifactId>
<version>1.0</version>
<properties>
<git.project>Test/Project</git.project>
<git.project.checkout.directory>${basedir}/src/php/main/${git.project}</git.project.checkout.directory>
<git.project.checkout.exists.file>${git.project.checkout.directory}/.git/index</git.project.checkout.exists.file>

<!-- And another profile for when the file exists, not shown for brevity -->

I've run mvn compile which tells me the file it tests for, done ls -l on the file to verify it exists, and then run again. For some reason, the test fails.
Help!
Profiles are determined prior to applying properties from the pom
<missing>${git.project.checkout.exists.file}</missing> won't work from the value in your pom.xml
If it was provided on commandline then I believe it would work
Otherwise you need to include the value directly
<missing>/src/php/main/Test/Project/.git/index</missing>

i have main pom.xml
i like to change from the main mvn command line cli which I'm using and change the :
<argument>${docker.image}</argument>
argument in only in the submodule :
module_y profile NOT module_x
this is the command I'm executing now :
mvn clean install -Ddocker_build=build
<artifactId>foo</artifactId>
<version>b1</version>
<packaging>pom</packaging>

<modules>
<module>module_x</module>
<module>module_y</module>
</modules>
this is the section in the module_x and module_y
<profiles>
<profile>

in short, how do i change only the property value ${docker.image} in profile docker_build in module_y from main mvn run?
If you cannot change the POMs, this cannot be done.
The only possible approach would be to build the modules separately (by using -pl module_x -am or something like that) and use different command line parameters in both cases.
I'm trying to print the current profile that is active running a build of a Maven Project.
I'm using the maven-antrun-plugin in order to print messages on the console, in combination with a property that refers to the current profile.
I have tried the following properties:
${project.activeProfiles[0].id}
${project.profiles[0].id}
But in both cases it prints the "string" as it is written, without resolving the variable.
This is my test:
<build>
<plugins>
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<phase>generate-resources</phase>
<goals>
<goal>run</goal>
</goals>
<configuration>
<tasks>
<echo>current active profile: ${project.activeProfiles[0].id}</echo>
</tasks>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
But this is the result that I obtain:
main:
[echo] current active profile: ${project.activeProfiles[0].id}
Any suggestion will be appreciated.
Thanks.
The maven-help-plugin offers what you need. It has an active-profiles goal.
You can add it to your pom or even call it from the command line (include it in your maven build call). The How can I tell which profiles are in effect during a build? section of the Maven profile introduction page will show you how. In short:
mvn help:active-profiles
As this does not work for you (see comments) here is another solution:
I think the active profiles (there can be more than one!) are not propagated as available variables - but properties are.
So set a custom property in the profile section and use that, like
<profiles>
<profile>
<id>default</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<properties>
<myProfile>default</myProfile>
</properties>
</profile>
<profile>
<id>debug</id>
<activation>
<property>
<name>debug</name>
</property>
</activation>
<properties>
<myProfile>debug</myProfile>
</properties>
</profile>
</profiles>

<configuration>
<tasks>
<echo>current active profile: ${myProfile}</echo>
</tasks>
</configuration>
</execution>
</executions>
</plugin>
</plugins>

you can add the maven-help-plugin in your pom to display always the active profile
<build>

I have numerous projects in IntelliJ, each of which has a pom.xml, and each of the projects' poms inherit from the master pom.xml. One profile (called test1) is present in two of the poms (for project2 and project4). When I run maven from the command line, specifying one project and the profile name, it works (the tests in that project are executed once) Here is the commmand:
mvn test -pl project2 -am -P test1
When I specify both projects (both of which have the same profile present), the tests in project4 are executed twice. Here is the command:
mvn test -pl project2,project4 -am -P test1
I would like the tests only to be executed once. I am running maven 3.1.1.
As a further complication, when I specify just project4, the tests in project2 get executed once, and the tests in project4 don't get executed at all. Here is the command:
mvn test -pl project4 -am -P test1
Here is pom.xml for project2:
<?xml version="1.0" encoding="UTF-8"?>

I figured out the answer to my own question (by looking carefully at some of our other projects' Maven test setup). I had to do two things:
Include a <skip>false</skip> element in the <configuration> aggregate in the surefire plugin.
Include a generic surefire <plugins> aggregate outside of the <profiles> section. This one has <skip> set to true and prevents tests being run unless they are in a profile. Here is what the section looks like:
<build>
<plugins>
<!-- We don't want to run any tests without an active profile -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.9</version>
<configuration>
<skip>true</skip>
</configuration>
</plugin>
</plugins>
</build>
The problem was that the tests were running the default-test lifecycle phase and then they were running again in the test phase. After I made the change they only ran in the test phase.
I have question about maven. How can I disable buildnumber-maven-plugin through command line option. I want to run "mvn test" command on our continuous integration server, but this cmd failed because it trying to build a version and haven't access permission to our vcs (which is configured in tag). So it is possible disable it through cmd option or run only the tests without building new release version? Thanks for any help.
Use a profile to control which plug-ins are enabled during the build:
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>com.me.test</groupId>
<artifactId>demo</artifactId>
<version>1.0</version>
..
..
<profiles>
<profile>
<id>with-scm</id>
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>buildnumber-maven-plugin</artifactId>
<version>1.0</version>
<executions>
<execution>
<phase>validate</phase>
<goals>
<goal>create</goal>
</goals>
</execution>
</executions>
<configuration>
<doCheck>true</doCheck>
<doUpdate>true</doUpdate>
</configuration>
</plugin>
</plugins>
</build>
</profile>
</profiles>
</project>
The profile can be enabled by running Maven as follows:
mvn -Pwith-scm package
One approach would be to use a property in your pom to specify the execution phase of the build number plugin, as shown below.
<project>
..
<properties>
<buildnumber.plugin.phase>validate</buildnumber.plugin.phase>
..
</properties>
..
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>buildnumber-maven-plugin</artifactId>
<version>1.2</version>
<executions>
<execution>
<phase>${buildnumber.plugin.phase}</phase>
<goals>
<goal>create</goal>
</goals>
</execution>
</executions>
<configuration>
..
</configuration>
</plugin>
</plugins>
..
</project>
Then provide the property on the command line to disable the plugin, as shown in the following example.
mvn install -Dbuildnumber.plugin.phase=none
mvn clean install deploy -Dbuildnumber.phase=none
You may skip failure without change pom.xml in project. Please look at my answer at Disable maven build number plugin
I'm looking into the Maven Wagon Plugin to attempt uploading some artifacts to remote UNC Server shares (\\servername\share\directory\to\put\to), and I have gotten it configured to work like so in the POM:
<build>
<extensions>
<extension>
<groupId>org.apache.maven.wagon</groupId>
<artifactId>wagon-file</artifactId>
<version>1.0-beta-7</version>
</extension>
</extensions>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>wagon-maven-plugin</artifactId>
<version>1.0-beta-3</version>
<executions>
<execution>
<id>upload-jar-to-folder</id>
<phase>deploy</phase>
<goals>
<goal>upload</goal>
</goals>
</execution>
</executions>
<configuration>
<fromDir>${project.build.directory}</fromDir>
<includes>*</includes>
<url>file://localhost///${servername}/${sharename}</url>
<toDir>directory/to/put/artifact</toDir>
</configuration>
</plugin>
...
</build>
This works great for one server when I pass in -Dservername=x -Dsharename=y, but how can I scale it out so I can run a deploy for QA or Prod where I have multiple servers to deploy to?
I've considered (and written) a script to run mvn wagon:upload -Penvironment# multiple times--once for each server--but this seems flawed to me. If I'm shelling out to a script to handle this process, I could just as well script out the entire deploy, too. However, this takes away from the usefulness of Wagon (and Maven)...
Is there a way to run multiple <executions> for one goal? For instance, running multiple profile configured wagon:upload tasks when I just run mvn deploy -Pqa?
If you want to use multiple profiles you could just use: mvn deploy -Denv=qa and trigger some profiles on this property and define the configuration for your severs in the profiles. For this kind of profile activation look at
http://maven.apache.org/guides/introduction/introduction-to-profiles.html
and search for
-Denvironment=test
