[jira] Commented: (MRELEASE-271) perform goal sometimes fails with multi-module projects

["Benjamin Bentmann (JIRA)" <ji...@codehaus.org>]

    [ http://jira.codehaus.org/browse/MRELEASE-271?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=159677#action_159677 ] 

Benjamin Bentmann commented on MRELEASE-271:
--------------------------------------------

bq. This behaviour is back when using the release plugin in tandem with maven-javadoc-plugin 2.5. 
Owen, can you be more specific about the exact point of the build that fails, maybe provide a log? For instance, does it fail during the site generation or during the normal build?

My guess is that is breaks during the site generation. If so, have you tried to exclude the new {{javadoc:*aggregate}} mojos introduced in version 2.5 of the Javadoc plugin as outlined in [Selective Javadocs Reports|http://maven.apache.org/plugins/maven-javadoc-plugin/examples/selective-javadocs-report.html]?

>    Affects Versions: 2.0-beta-4, 2.0-beta-6

> We have a multi-module maven project that has recently started failing in the release:perform goal.  
> We have just added a couple more modules but do not know if that is the cause of the failure.  It seems that the release:perform fails to compile the source after the SCM tag and checkout.  The failure says that it cannot find a dependent jar but it is that jar that it is supposed to be building and releasing!  I updated to use the latest 2.0-beta-6 release plugin version but this did not help. 
> Upon receiving feedback in the maven users group that others have seen this behavior I followed their advise and added <configuration> <preparationGoals>clean install</preparationGoals></configuration> to my parent pom which did fix the problem.
> Why is the release goal failing now?  When do I and when do I not need these changes to my pom?  I will attach pom and build logs in hopes this can be fixed soon, let me know if you need additional information.
