> Modules in multi-module projects are "built" too often

> Key: MJAVADOC-171
> URL: https://jira.codehaus.org/browse/MJAVADOC-171
> Project: Maven 2.x Javadoc Plugin
> Issue Type: Bug
> Affects Versions: 2.3
> Environment: Maven 2.0.8, Linux
> Reporter: Stefan Seidel
> Assignee: Herve Boutemy
> Priority: Critical
> Fix For: 2.8
>
> Attachments: 2.2.log, 2.3.log, mjavadoc171.patch, mvnexec.zip
>
>
> In a multi-module project, all modules are "built" twice for each module.
> This leads to huge performance problems when many modules are in a project.
> In the attached sample project, the xmlbeans plugin is executed 27 times for
> a project with one parent module and two submodules. 18 of these executions
> can be attributed to the javadoc plugin. With version 2.2, only 3 invocations
> (once for each project) are caused by the javadoc plugin.
