Maven 2 将非OSGI jar依赖项添加到Liferay 7 CE中基于maven的MVC portlet中

我已经为Liferay 7 CE创建了一个MVC Portlet，它具有相应的maven原型（如所述）。我在项目的POM文件中添加了一些额外的非OSGI jar文件作为项目依赖项。当我在liferay portal server上部署该项目时，OSGI容器无法解析所创建模块的依赖关系，捆绑包仍处于安装阶段。我想以自动方式将非OSGI jar文件及其可传递依赖项添加到to包中。我该怎么办？本模块的内容如下：

如果com.livitSolutions.jts未准备好OSGi，您可以通过或SpringRoo将其包装起来，这里是Liferay社区博客，用于添加对OSGi模块的依赖关系：

---

看看这些选项是否符合您的要求。你应该选择这个博客中提到的第三个或第四个选项。这在我的情况下是有效的。

在我们的一个项目中，我们也遇到了类似的问题。我注意到最后一个答案是从1月15日开始的，我认为最好在Liferay的博客文章中加入一个有用的回复。这让我们意识到，我们必须从博客中选择选项3或4，如前一个答案所述

因此，这实际上是一个常见的误解——使用依赖关系管理器在gradle中构建与没有类似依赖关系管理器的OSGi运行时环境之间存在差异

OSGi故意不下载依赖项，特别是可传递依赖项，因为这会导致环境不稳定

编译代码时，构建过程将包含可传递的依赖项，但BND不是编译器，它只是构建jar文件并包含您告诉它的内容

所以，是的，在正常情况下，您必须自己包含所有依赖项和可传递依赖项。这就是说，一些项目在其可传递依赖项中不使用“可选”标记，因此OSGi将其视为必须使用的标记。您必须在BND文件中添加classpath声明，以强制排除那些您确实不想要的包

这绝对是一个皮塔，但这样做是有原因的。OSGi环境是您的运行时环境，您希望主动管理并了解它。作为管理员，您希望了解您的模块正在使用什么，并适当地管理部署。从管理的角度来看，您不希望环境自己下载东西（通常情况下，这在生产环境中是不可能的）

谢谢，我读了那篇文章。但我想将Maven依赖项及其可传递依赖项自动添加到最终jar文件包的Manifest.MF中。你有什么建议吗？对不起，我现在还不知道。如果我遇到任何与你的要求有关的事情，我会告诉你的。
