------------------------------------------
save the following script as gen-bug.sh, the you can compare the two command
result:
- ./gen-bug.sh # ok, output 100%
- ./gen-bug.sh -Daggregate # error, cannot find 100%
{code:bash}
#!/bin/sh
set -e
bug=$(mktemp -d)
trap 'rm -rf "$bug"' EXIT
mkdir -p "$bug/src/main/java" "$bug/src/test/java"

> Empty report for single-module project with 'aggregate=true'
> ------------------------------------------------------------
>
> Key: SUREFIRE-2004
> URL: https://issues.apache.org/jira/browse/SUREFIRE-2004
> Project: Maven Surefire
> Issue Type: Bug
> Components: Maven Surefire Report Plugin
> Affects Versions: 2.4, 3.0.0-M5
> Reporter: Alexander Kriegisch
> Priority: Major
>
> 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.
