如何在jQAssistant中聚合具有复杂父结构的多模块maven项目的扫描结果？

Question

关于使用-Djqassistant.useExecutionRootAsProjectRoot=true在单个存储目录中聚合多模块maven项目的数据，我遇到了一个问题。

下面是我的项目的结构

root-project [NO PARENT]
----/project-A [PARENT company-parent-pom-A]
----/project-B [PARENT company-parent-pom-B]

我在根项目上运行以下代码

mvn clean install -DskipTests=true com.buschmais.jqassistant:jqassistant-maven-plugin:1.2.0:scan -Djqassistant.useExecutionRootAsProjectRoot=true

但它显示以下错误。

Failed to execute goal com.buschmais.jqassistant:jqassistant-maven-plugin:1.2.0:scan (default-cli) on project root-project: Cannot re-use store instance from reactor. Either declare the plugin as extension or execute Maven using the property -Djqassistant.store.lifecycle=MODULE on the command line.

因此，我添加了-Djqassistant.store.lifecycle=MODULE并运行以下命令

mvn clean install -DskipTests=true com.buschmais.jqassistant:jqassistant-maven-plugin:1.2.0:scan -Djqassistant.useExecutionRootAsProjectRoot=true -Djqassistant.store.lifecycle=MODULE

现在构建成功了。但在扫描root-project时，插件最终会重置存储目录。所以之前收集的所有数据都被删除了。这是jqa-maven-plugin的问题，还是我做错了什么？

您所描述的设置应该可以正常工作，很可能您发现了一个bug。你能在https://github.com/buschmais/jqa-maven-plugin上报道这件事吗？
