A default-activated profile in the profiles.xml file is not deactivated when
another profile is activated explicitly
--------------------------------------------------------------------------------------------------------------------
Key: MNG-4337
URL: http://jira.codehaus.org/browse/MNG-4337
Project: Maven 2
Issue Type: Bug
Components: Profiles
Affects Versions: 2.2.1, 2.1.0, 2.0.10
Environment: Java 1.6.0, Debian GNU/Linux 5.0
Reporter: Clemens Fuchslocher
Attachments: profiles.tar.gz
The behavior of the activeByDefault element inside a POM is documented in
[Introduction to Build
Profiles|http://maven.apache.org/guides/introduction/introduction-to-profiles.html]:
{quote}
All profiles that are active by default are automatically deactivated when a
profile in the pom is activated on the command line or through its activation
config.

And it also works this way:
{noformat}
$ tar -zxvf profiles.tar.gz
$ cd profiles/internal
$ mvn help:all-profiles
...
Profile Id: red (Active: true , Source: pom)
Profile Id: green (Active: false , Source: pom)
Profile Id: blue (Active: false , Source: pom)
...
$ mvn help:all-profiles -P blue
...
Profile Id: blue (Active: true , Source: pom)
Profile Id: red (Active: false , Source: pom)
Profile Id: green (Active: false , Source: pom)
...
$ mvn help:active-profiles
...
The following profiles are active:
- red (source: pom)
...
$ mvn help:active-profiles -P blue
...
The following profiles are active:
- blue (source: pom)
...
$ mvn help:effective-pom
...
<properties>
<color>red</color>
</properties>
...
$ mvn help:effective-pom -P blue
...
<properties>
<color>blue</color>
</properties>
...
{noformat}
But if the profiles are defined in the profiles.xml file, then the behavior of
the activeByDefault element is changed unexpectedly: The red profile and the
color property is always active and red:
{noformat}
$ tar -zxvf profiles.tar.gz
$ cd profiles/external
$ mvn help:all-profiles
...
Profile Id: red (Active: true , Source: profiles.xml)
Profile Id: green (Active: false , Source: profiles.xml)
Profile Id: blue (Active: false , Source: profiles.xml)
...
$ mvn help:all-profiles -P blue
...
Profile Id: blue (Active: true , Source: profiles.xml)
Profile Id: red (Active: true , Source: profiles.xml)
Profile Id: green (Active: false , Source: profiles.xml)
...
$ mvn help:active-profiles
...
The following profiles are active:
- red (source: profiles.xml)
...
$ mvn help:active-profiles -P blue
...
The following profiles are active:
- blue (source: profiles.xml)
- red (source: profiles.xml)
...
$ mvn help:effective-pom
...
<properties>
<color>red</color>
</properties>
...
$ mvn help:effective-pom -P blue
...
<properties>
<color>red</color>
</properties>
...
{noformat}
Principle of Least Surprise?
Maybe a bug.
