Maven：在一个版本中对不同的模块使用不同的全局配置文件

Question

I am trying to build a multi-module POM project.

In my settings.xml I keep a number of profiles containing details for connecting to various servers. This are used by the persistence units of the modules.

What I need is to use two different profiles (one for one module and an other one for the rest of them) in the same build. Not build all profiles in once, as some other questions here on SO ask for.

My best case scenario would be to be able to set one profile as default, what I have now, and just assign the other profile to the one module that needs it, without having to define the profile again anywhere else.

Important, I have managed to get the functionality I need by using mvn with different profiles on the terminal but I want to be able to do this through the pom so that I can build the whole thing in Netbeans and Jenkins.

Is that even possible?

Answer 1

Initially i thought maybe some thing like this.

in settings.xml profile

    <activation>
    <property>
      <name>activator.one</name>
      <value>true</value>
    </property>
    </activation>

in pom.xml of a module

    <properties>
       <activator.one>true</activator.one>
    </properties>

maybe this will activate the profile with the activator only when the property is set to true. Which is then only in the pom of a certain module.

BUT http://maven.40175.n5.nabble.com/Activating-a-profile-in-settings-xml-based-on-a-property-set-in-pom-xml-td512562.html

Profiles can not be activated during build!

Thus

Is it not better to name the profiles different in your modules so that the names are totally different. And activate them all. Like connections_mysqldb_module_a, connections_hsqldb_module_b You'll have bunch of profiles but if you make sure the names do not overlap between modules you can always choose on a per module basis and still build everything at once.
