Aggregate goal without a pom

[lionelve]

I'm trying to aggregate the tests results from multiple projects. Each of those projects have their own pom and run fine. There is no project really aggregating them all so I figured I could run the goal without a pom.

The aggregator mojo has the requiresProject property set to false:

serenity-maven-plugin/src/main/java/net/serenitybdd/maven/plugins/SerenityAggregatorMojo.java

Line 33 in b8e1273

@Mojo(name = "aggregate", requiresProject = false, requiresDependencyResolution = ResolutionScope.RUNTIME, aggregator = true)

If I understand things correctly this implies that the goal can be executed without having a pom file. However, this fails with a NullPointerException from:

serenity-maven-plugin/src/main/java/net/serenitybdd/maven/plugins/MavenProjectHelper.java

Line 25 in b8e1273

System.setProperty("project.build.directory", session.getCurrentProject().getBasedir().getAbsolutePath());

.

I'm executing the goal like this

mvn -B -Dserenity.outputDirectory=target/site/serenity -X net.serenity-bdd.maven.plugins:serenity-maven-plugin:aggregate

The full error is this:

[ERROR] Failed to execute goal net.serenity-bdd.maven.plugins:serenity-maven-plugin:2.6.0:aggregate (default-cli) on project standalone-pom: Execution default-cli of goal net.serenity-bdd.maven.plugins:serenity-maven-plugin:2.6.0:aggregate failed. NullPointerException -> [Help 1]

If this is not meant to work without a pom should requiresProject be true?
