Grails-使用maven构建模块化项目

我正在开发Grails2.3.4应用程序，并试图为构建目的添加maven（3.1.1）。我这样做是因为我的项目是模块化的（2个插件，1个应用程序-现在，以后会有更多插件），我希望有支持它的工具（我没有使用Gradle，但那完全是另一个主题）。最近我发现了一些我不理解的问题，这让我的大脑受伤。我将非常感谢对他们的任何帮助

我的项目结构如下所示：

my_project/
 my_project-domain/ (plugin)
  pom.xml
 my_project-services/ (plugin)
  pom.xml
 my_project-webap/ (app)
  pom.xml
 pom.xml

我的父母pom.xml：

为什么由

mvn grails:test app执行的集成测试失败，以及如何修复它？我需要exec命令用于某些特定目的，我希望能够依赖它。这是我最大的问题，我完全不明白原因是什么

为什么

mvn grails:tests应用程序
会导致双重测试执行

为什么我需要为tomcat添加h2依赖项？在我的数据源中，我只有mongodb配置，我只想坚持使用它，并且每次执行集成测试时都不会看到以下错误：
