When trying to use an embedded launcher created from the classpath
(https://github.com/apache/maven-verifier/blob/17ebffa2467caa59f1e47c302ac03d9e00d8c314/src/main/java/org/apache/maven/it/Embedded3xLauncher.java#L124),
launching fails with
{code}
-Dmaven.multiModuleProjectDirectory system property is not set
{code}
A similar issue was once reported and fixed for m2e at
https://bugs.eclipse.org/bugs/show_bug.cgi?id=462944.
The reason is
https://github.com/apache/maven/blob/706d9319f14b507f3c3deeba4eeda1a51a531c9b/maven-embedder/src/main/java/org/apache/maven/cli/MavenCli.java#L351
which now requires this property to be set. This has been introduced by
https://issues.apache.org/jira/browse/MNG-5767 in Maven 3.3.1
