Ok, turns out reproducing this locally is a little more complicated.
# A. Preparation
1. You need to use .mvn/maven.config in order to block Maven subprocesses
(`build-drools-test-coverage-jars` invocation of `maven-invoker-plugin` on
`drools-test-suite`) from downloading content from apache.snapshots.
2. You gotta make sure that there are no JARs inside the
`drools-test-coverage/test-suite/src/test/resources/kjar/` folder. Otherwise
the `maven-invoker-plugin` execution mentioned above doesn't kick in.
3. You gotta build BOMs first so that they get installed in the local Maven
repository and therefore can be seen by the Maven subprocesses mentioned in 1.
- `mvn install -f bom && mvn install -f build-parent`
After performing all those steps, build the tree skipping all tests (just so
it's quick):
# B. Build
```
mvn clean install -pl :drools-test-suite -am -DskipTests
```
Then, to reproduce the original issue, run:
```
mvn clean install -pl :drools-test-suite
```
Which will give you these logs:
```
