Subject [jira] Updated: (MNG-4441) Profile Activation Regression in Maven3
Date Sat, 02 Jan 2010 15:45:55 GMT

     [ http://jira.codehaus.org/browse/MNG-4441?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Benjamin Bentmann updated MNG-4441:
-----------------------------------

    Attachment: pom.xml

Based on the little information given, I created this example project. This works the same
with Maven 2 and 3, i.e. the profile is not activated when the output directory exists before
the invocation of "mvn clean generate-sources".

I also checked the Maven 2 sources and didn't see any spots that would reevaluate profiles
in the middle of the build. In other words, both Maven 2 and Maven 3 evaluate profiles only
once, namely before any build operation is performed.

I have a problem with profile activation in Maven3.
> I have a profile that activates if target/generated-sources/castor is missing and includes
castor in the build process that will create that directory and generate the sources into
it.
> If the directory exists and I do mvn clean install, the build fails with maven 3. Maven
does not activate the profile since the directory exists at the beginning. But the clean step
will delete it of course and so the sources are missing and the build fails. With maven 2
this works.
