Lukas Theussl commented on MSITE-621:
-------------------------------------
Shouldn't this be reported to MNG as well? If m2 does nothing and m3 removes
everything, then this is a dangerous regression IMO.

> Key: MSITE-621
> URL: https://jira.codehaus.org/browse/MSITE-621
> Project: Maven 2.x and 3.x Site Plugin
> Issue Type: Bug
> Components: documentation
> Affects Versions: 3.0
> Environment: Apache Maven 3.0.3 (r1075438; 2011-02-28 11:31:09-0600)
> Maven home: D:\maven\apache-maven-3.0.3\bin\..
> Java version: 1.6.0_24, vendor: Sun Microsystems Inc.
> Java home: D:\j2sdk1.6.0_24\jre
> Default locale: en_US, platform encoding: Cp1252

>
>
> On this page:
> http://maven.apache.org/plugins/maven-site-plugin/maven-3.html#Old_configuration_Maven_2__3
> There is this little code snippet:
> {code}
> <reporting>
> <excludeDefaults>true</excludeDefaults>
> <outputDirectory></outputDirectory>
> <plugins>
> {code}
> Notice the empty outputDirectory property? Well, in Maven 2.2.1 that appears
> to be ignored. In Maven 3.0.3 however, it deletes the entire project! The
> documentation for this should be changed as soon as possible. We lost a bit
> of work because of this.
