HI My project structure is like this
parentPrj
pom.xml
childModule1
pom.xml
ChildModule2
pom.xml
ChildModule2
pom.xml
I dont want to build all the child builds so I am building each module based on the profile (something like below)
// here is the some sample code
<profiles>
<profile>
<id>child1</id>
<activation>
<activeByDefault>false</activeByDefault>
</activation>
<modules>
<module>childModule1</module>
</modules>
</profile>
<profile>
<id>child2</id>
<activation>
<activeByDefault>false</activeByDefault>
</activation>
<modules>
<module>childModule2</module>
</modules>
</profile>
<profile>
<id>child3</id>
<activation>
<activeByDefault>false</activeByDefault>
</activation>
<modules>
<module>childModule3</module>
</modules>
</profile>
</profiles>
// end of the sample code
My goal is when I run child1 profile I wanted to build childModule1 project and update the parent version of the pom in all three child modules .. Can you help me how to do that? I have tried many options like
release:update-versions -DautoVersionSubmodules=true ,mvn versions:set etc..

This question already has answers here:
Activating a Child Profile from a Parent Profile
(2 answers)
Closed 5 years ago.
I have two pom's an aggregate and a child, the child has a profile I would like to be activated based upon a property set in the parents profile eg.
parent pom.xml
<profiles>
<profile>
<id>emptyModules</id>
<modules>
<module>child</module>
</modules>
<properties>
<emptyModules>true</emptyModules>
</properties>
</profile>
</profiles>
The child has two profiles one with some modules the other without
<profiles>
<profile>
<id>modules</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<modules>
<module>module1</module>
<module>module2</module>
</modules>
</profile>
<profile>
<id>emptyModules</id>
<activation>
<property>
<name>emptyModules</name>
<value>true</value>
</property>
</activation>
</profile>
</profiles>
When I activate the parent emptyModules profile I want the child emptyModule profile to activate, however the default profile is used instead! Any ideas?
You can activate profiles based on properties:
<profiles>
<profile>
<activation>
<property>
<name>someprop</name>
</property>
</activation>
...
</profile>
</profiles>
This could be used to activate a parent and child profile at once.
Using maven 3.1.1
In my parent pom I have:
<groupId>com.samples</groupId>
<artifactId>parent</artifactId>
<version>1.0.0-SNAPSHOT</version>
<packaging>pom</packaging>
<name>Parent</name>
<modules>
<module>a</module>
<module>b</module>
<module>c</module>
</modules>
<profiles>
<profile>
<id>skip-c</id>
<modules>
<module>a</module>
<module>b</module>
</modules>
</profile>
...
But module c is still build with I build with:
mvn clean package -Pskip-c
How do I skip a submodule when building my parent project?
Your problem is that your complete module list is always active. You could use a default profile instead.
<groupId>com.samples</groupId>
<artifactId>parent</artifactId>
<version>1.0.0-SNAPSHOT</version>
<packaging>pom</packaging>
<name>Parent</name>
<profiles>
<profile>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<modules>
<module>a</module>
<module>b</module>
<module>c</module>
</modules>
</profile>
<profile>
<id>skip-c</id>
<modules>
<module>a</module>
<module>b</module>
</modules>
</profile>
</profiles>
In addition to julschis comment some details:
Profiles do not replace the normal non profile content of the pom. Therefore, when using your profile, you get a, b and c from the normal pom, and a and b from the profile, therefore your profile is useless.
You need to remove your conditional modules from the main part and put it only into profiles (usually an activeByDefault Profile).
<profile>
<id>default</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<modules>
<module>a</module>
<module>b</module>
</modules>
</profile>
<profile>
<id>add-c</id>
<modules>
<module>a</module>
<module>b</module>
<module>c</module>
</modules>
</profile>
So it is the other way around, profiles cannot remove anything, but only add or override content.
This technique is called reactor pruning and described here: http://www.blackbuild.com/how-to-really-use-maven-profiles-without-endangering-your-karma/
Your could also use the new functionality from https://jira.codehaus.org/browse/MNG-5230, and simply call (this requires Maven 3.2.1+)
mvn clean package -pl !c
Deactivation of profiles can be done using Maven 2.0.10 + .
http://maven.apache.org/guides/introduction/introduction-to-profiles.html
Deactivating a profile
Starting with Maven 2.0.10, one or more profiles can be deactivated using the command line by prefixing their identifier with either the character '!' or '-' as shown below:
mvn groupId:artifactId:goal -P !profile-1,!profile-2
This can be used to deactivate profiles marked as activeByDefault or profiles that would otherwise be activated through their activation config.
I have the following profile in parent POM :
<profile>
<id>myprofile</id>
<activation>
<activeByDefault>false</activeByDefault>
</activation>
<modules>
<module>module1</module>
<module>module2</module>
</modules>
</profile>
Now in my child POM of module2 I have the following profile :
<profiles>
<profile>
<id>module2profile</id>
<build>
<finalName>mywar</finalName>
<plugins>
....
</plugins>
</build>
</profile>
</profiles>
My requirement is that from the parent POM profile, instead of referring "module2", I want to refer to profile "module2profile".
I need this because in my module2 I am creating 2 different war files (one that is created normally while the other is created by "module2profile").
I have the following XML in my maven POM.xml:
<profiles>
<profile>
<id>default</id>
<activation>
<activeByDefault>true</activeByDefault>
<property>
<name>default</name>
<value>!disabled</value>
</property>
</activation>
<modules>
<module>m1</module>
<module>m2</module>
<module>m3</module>
</modules>
</profile>
<profile>
<id>x</id>
<modules>
<module>m1</module>
</modules>
</profile>
</profiles>
What I'm trying to achieve is this:
When I run mvn install, I want it to build m1, m2 and m3 projects.
When I run mvn install -Px, I want it to only build m1.
My current problem is that with the code above, option 2 builds all m1, m2 and m3.
Found the solution guys, define 'x' profile first and the 'default' and it works fine (insane Maven!!). Here's the final result:
<profiles>
<!-- DO NOT CHANGE THE *ORDER* IN WHICH THESE PROFILES ARE DEFINED! -->
<profile>
<id>x</id>
<modules>
<module>m1</module>
</modules>
</profile>
<profile>
<id>default</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<modules>
<module>m1</module>
<module>m2</module>
<module>m3</module>
</modules>
</profile>
</profiles>
You can disable maven profiles that have runByDefault set to true from the command line like so:
mvn install -P !default
Note, this requires Maven version 2.0.10.
Just add a space after -P the sintax of the command is
mvn install -P x
And not like you are using
mvn install -Px
Take a look at Maven - Introduction to profiles
In maven, once you define your modules in you pom.xml all profiles aggregate the modules defined in them: (relevant part only)
<project>
<modules>
<module>module1</module>
</modules>
<profiles>
<profile>
<id>pr1</id>
<modules>
<moudule>module2</module>
</modules>
If you perform a mvn clean it will pass the command to module1.
If you issue mvn clean -Ppr1 it will pass along to module1 and module2.
I wonder if in maven 3 it is possible to have a pom.xml with submodules and override this. I mean to execute a profile that instead of add their own modules to the build force those like:
<project>
<!-- omitted -->
<modules>
<!-- modules -->
</modules>
<build>
<!-- build -->
</build>
<profiles>
<profile>
<!-- This profile with no modules -->
</profile>
</profiles>
</project>
The requirement might sound silly, but I just want to know if there is a mechanism like in plugin configuration.
<configuration self.combine="override"

It's not possible. Profile configuration is always merged with main configuration, so you only can add modules in your case.
What you can do instead, however, is to create a some kind of "default" profile (by <activeByDefault>true</activeByDefault> in <activation> section) that is enabled when no other profiles are invoked and put your default modules' list there. Then, when no profile is specified on Maven build call, this "default" profile is used, but when you call explicitly at least one profile, it's not, so you can this way define modules' list from scratch.
While the question is old, Google still ranks it highly, so it makes sense to add a new answer.
You can use the activation by absence of a property trick to achieve what you want.
<profiles>
<!-- By default, include the modules -->
<profile>
<id>full-build</id>
<activation>
<!-- Activation by absence of a property. Run normally, without -Dskip-modules -->
<property>
<name>!skip-modules</name>
</property>
</activation>
<modules>
<module>module1</module>
<module>module2</module>
<module>module3</module>
</modules>
</profile>
<!-- No-modules build -->
<profile>
<id>no-modules</id>
<activation>
<!-- Activation by a property. Run with -Dskip-modules to activate -->
<property>
<name>skip-modules</name>
</property>
</activation>
<modules>
</modules>
</profile>
</profiles>
You can do things like this:
<profiles>
<profile>
<id>run-xyz</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<modules>
<module>www-ab</module>
<module>www-cd</module>
</modules>
</profile>
<profile>
<id>run-its</id>
<activation>
<activeByDefault>false</activeByDefault>
</activation>
<modules>
<module>www-db</module>
<module>www-it</module>
</modules>
</profile>
</profiles>
If you are talking about such things. But i would recommend to be very carefull about such things.
It's only the question how you set activeByDefault. With this it's possible to create more or less any combination.
