Dennis Lundberg commented on MNG-4516:
--------------------------------------
If you read this:
http://maven.apache.org/guides/introduction/introduction-to-profiles.html
you will see:
"As of Maven 2.0.9, the tags <exists> and <missing> could be interpolated. Supported
variables are system properties like ${user.home} and enviroment variables like ${env.HOME}.
Please note that properties defined in the POM itself are not available for interpolation
here."
> Contradiction between the documentation and Maven's behavior related to profile-activation
with multiple criteria

> Key: MNG-4516
> URL: http://jira.codehaus.org/browse/MNG-4516
> Project: Maven 2 & 3
> Issue Type: Bug
> Components: Profiles
> Affects Versions: 2.2.1
> Reporter: Barnabas Bodnar
> Priority: Critical
> Attachments: debug_output.txt, output.txt, pom.xml

> The chapter 5.3.1 of the Maven Complete Reference (edition 0.2.1, Novemeber 2009) speaks
unambiguously about considering a logical "AND" between more activation-conditions of a profile
(cit.: "A profile is activated when all activation criteria has been satisfied. For example,
a profile could list an Operating System family of Windows, and a JDK version of 1.4, this
profile will only be activated when the build is executed on a Windows machine running Java
1.4.").
> Suprisingly, Maven's real behavior suggests, that the logical "OR" operator is used.
The attached demo project contains a profile with two activation-criteria: a property and
the existence of a file. As the output shows (attachement output.txt), the fulfillment of
a single criterion is enough for activating the profile. Also the corresponding implementation
in the Maven core expresses the intention to use an "OR" logic (maven-project/src/main/java/org/apache/maven/profiles/DefaultProfileManager.java
r813685 (branch 2.2.x), line 268):
> for ( Iterator activatorIterator = activators.iterator(); activatorIterator.hasNext();
)
> {
> ProfileActivator activator = (ProfileActivator) activatorIterator.next();
> if ( activator.canDetermineActivation( profile ) )
> {
> if ( activator.isActive( profile ) )
> {
> return true;
> }
> }
> }
> return false;
> As I'm considering the documentation's variant more reasonable, I'm reporting this as
a bug instead of a documentation-issue.
