Грешка при компилиране на Maven поради липсващи генерирани класове

Преминах към нова настройка и сега командата mvn clean compile се проваля с това:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default-compile) on project OpenPatricianModel: Compilation failure: Compilation failure:

От грешката става ясно, че не могат да бъдат намерени класове. Тези класове са генерирани по време на фазата generate-sources и след това са добавени към ресурсите с build-helper-maven-plugin. Следователно това изглежда различно от Защо Maven генерираните източници не се компилират?

Изпълнението на командата maven с -X показва, че изходната папка на генерираните java източници всъщност е на класовата пътека и файловете дори се откриват като остарели (защото са новосъздадени):

[DEBUG] Using compiler 'javac'.
[DEBUG] Adding /home/andi/development/intellij/OpenPatrician/OpenPatricianModel/target/generated-sources/annotations to compile source roots:

  /home/andi/development/intellij/OpenPatrician/OpenPatricianModel/target/generated/src/main/java
  /home/andi/development/intellij/OpenPatrician/OpenPatricianModel/target/generated-sources/annotations

Изглежда обаче, че тези източници не са компилирани.

Ето части от файла effictve pom:

Проектът може да бъде компилиран от IDE (IntelliJ) и приложението се изпълнява.
