我不想将我的服务版本硬编码到 metainfo.xml 中，我可以这样做吗？
<service>
<name>DUMMY_APP</name>
<displayName>My Dummy APP</displayName>
<comment>This is a distributed app.</comment>
<version>0.1</version> --------------This I don't want to hardcode, Can I doit?
<components>
...
</components>
</service>
我使用 maven 作为我的构建工具。
这可以通过使用 maven 的资源过滤来完成。需要三个步骤：
例如，假设您想使用与项目 maven 版本标识符相同的版本${project.version}，作为 metainfo.xml 文件中的版本。您将替换<version>0.1</version>为<version>${project.version}</version>. 然后在您的 pom 文件中，您需要列出需要过滤的 metainfo.xml 文件。此步骤的过程将根据您捆绑自定义 Ambari 服务（rpm、程序集等）的方式而有所不同。通常，在列出源（要包含在包中的内容）时，无论您使用哪个插件，您都需要指定 metainfo.xml 文件的路径并确保过滤设置为 true。
现在让我们假设您要创建一个 rpm 来安装您的工件。它看起来像这样：
您的项目结构应如下所示：
--src
--main
--resources
--configuration
--scripts
metainfo.xml
您的 pom 文件将如下所示：
<?xml version="1.0"?>

这将创建一个 rpm，安装后会将您的服务添加到 HDP 2.3 堆栈。安装 rpm 后，您必须重新启动 ambari-server 以确保选择新的服务定义。
更新：要为其他堆栈创建额外的 RPM，您需要：
