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.
