Alexander Kriegisch updated SUREFIRE-2004:
------------------------------------------
    Description: 
Using either {{-Daggregate=true}} on CLI or {{<aggregate>true</aggregate>}} in 
the plugin configuration leads to an empty report (i.e. zero tests reported) 
when e.g. executing

{code:none}
mvn -Dmaven.test.failure.ignore=true -Daggregate=true clean verify 
surefire-report:report-only
{code}

in the context of a single-module project. As soon as I make the root module 
pom-packaged and move the tests to into a child module, the aggregate report 
works.

FYI, if I do not define the plugin and its version in my POM at all, the 
default version 2.4 used by Maven on my workstation has the same problem, so 
this does not seem to be a 3.0.0-M5 issue only.

----

Background info about how and why I actually stumbled across this problem: I 
have an OSS multi-module project with lots of expensive UI tests. The full 
build can take 2.5 hours. I wanted to test a few CLI settings before creating 
an additional GitHub CI build workflow which can be run on demand and always 
runs all tests in all modules (ignoring errors and failures), no matter what. 
In the end, it is supposed to create a single-file aggregate HTML report which 
can easily be attached to the build and later is available for download, if the 
user so chooses in order to analyse failing tests comfortable and without 
having to scroll through build logs.  You get the picture, I guess. In the 
original project, there is a pom-packaged root POM, so the problem described in 
this issue does not occur there. I simply created a single-module dummy project 
in order to verify the effect of certain build options quickly and not having 
to wait for the slow original build to finish. Eventually, I noticed the issue 
described above.
