Problem with site generation - maven-site-plugin
Hi to all,
I've stumbled upon the following problem during the site generation
mojo-parent (issue-105)$ mvn site site:stage
..

This can be reproduced with 3.0.5 up to 3.6.1.
Versions 3.6.2 and 3.6.3 are working fine.
This means using maven-site-plugin 3.9.0 only working with Maven 3.6.2+
...in contradiction to the site[1] which says it is requirement 3.0..
Or has someone a different explanation for this?
Kind regards

Yes, but there's an explicit dependency on classorlds in this plugin
that might be conflicting with the one we pull in transitively. The
stack trace here smells like a dependency conflict to me.

removing Maven 2 code is a good simplification
but FYI it won't remove dependency on plexus-classworld: it's the core of all
plugins classloading mechanism to have independant plugins
didn't yet have time yet to dig, but perhaps the way maven-site-plugin invokes
reporting plugins causes some dependencies on classloaders: really need the
stacktrace, because I know that the way such low level reporting plugin
classloading exceptions are reported are reported at the end against maven-
site-plugin by Maven core, even if it was the reporting plugin that reported
an issue to the maven-site-plugin

I still don't have full grasp of the cause, but I think we can remove
our dependency on plexus-classworlds completely by ripping out some
Maven 2 support. See

Re: Problem with site generation - maven-site-plugin
Posted by Elliotte Rusty Harold <el...@ibiblio.org>.
getInputLocation seems to have been added in plexus-utils 3.2.0.
The reproducible builds work for maven-site-plugin upgraded from
plexus 3.0.x to 3.3.0 in
https://github.com/apache/maven-site-plugin/commit/19be00a9bf2a410abb7132487dc24055060b2c70#diff-600376dffeb79835ede4a0b285078036
It's not immediately clear to me how the classpath for all this is
pulling in an earlier version of plexus-utils since maven-site-plugin
declares that dependency directly, but that's what seems to be
happening.

Re: Problem with site generation - maven-site-plugin
Posted by Hervé BOUTEMY <he...@free.fr>.
TLDR; issue fixed :)
tracked in https://issues.apache.org/jira/browse/MSITE-863
fixed in maven-reporting-exec 1.5-SNAPSHOT https://issues.apache.org/jira/browse/MSHARED-921
this is caused by Xpp3Dom class incompatibility with Xpp3DomUtils.mergeXpp3Dom(...):
- Xpp3Dom version is taken from Maven core classloader as exported: see http://maven.apache.org/ref/3.6.3/maven-core/core-extensions.html
- Xpp3DomUtils is taken from current plugin classloader
with recent upgrade of plexus-utils in maven-site-plugin 3.9.0, Xpp3DomUtils is a recent version (plexus-utils >= 3.2.0) that expects to merge the input location (see https://github.com/codehaus-plexus/plexus-utils/issues/61)
but older Maven core versions don't have this input location field in Xpp3Dom, since they provide older plexus-utils that was upgraded to add location tracking in MNG-6597 for Maven 3.6.1
I fixed the issue by shading and older Xpp3DomUtils class into maven-reporting-exec
I'll release Maven Reporting Exec 1.5 soon, then Maven Site Plugin 3.9.1

Hervé

Hi Hervé,
you can reproduce the issue on mojohaus parent repository
(github.com:mojohaus/mojo-parent.git) and using the branch "issue-105"
and just:
mvn site site:stage
Using Maven 3.5.2 fails with the described issue.
