[jira] [Commented] (MSITE-873) The following plugins are not marked
@threadSafe in org.apache.maven.plugins:maven-site-plugin:3.9.1
[ https://issues.apache.org/jira/browse/MSITE-873?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17358680#comment-17358680 ]
Robert Krajewski commented on MSITE-873:
----------------------------------------
Site builds with recommended reports such as Javadoc, dependency checks, SpotBugs and so on, are roughly ten times slower than merely building Java projects and skipping tests. It's probably hard to speed up individual site report tasks, but allowing them to run in each module to run in parallel would really help.

> Hello Maven Site Plugin Team,
> This is my first post here, apologies in advanced if this post is not respecting conventions.
> There is currently an issue with the version 3.9.1 of maven-site-plugin when running in multithread environment.

> <plugin>
> <groupId>org.apache.maven.plugins</groupId>
> <artifactId>maven-site-plugin</artifactId>
> <version>3.9.1</version>
> </plugin>

> The setup is simple and reproducible 100%.
> Nowadays, maven multimode is very popular, especially among micro services pattern.
> For instance, within one maven project, possibility to have many multi module micro service.
>
> And often it makes sense to run maven commands on them in parallel.
>
> Unfortunately, the current maven multi module will yield this issue:
