带有 Apache Felix 插件的 Maven Web 项目

Question

使用 maven 创建一个简单的 osgi（部署到 virgo 服务器）项目的最佳方法是什么，用 pom 创建一个战争结构.xml Maven 描述符？

结构目标是

*.jsp
*.html
META-INF
MANIFEST (OSGI-CONFIG)
WEB-INF
  classes
  lib
  web.xml

然后当我创建一个项目时

这是我的 pom.xml

<packaging>war</packaging>

Felix 插件

<plugin>
    <groupId>org.apache.felix</groupId>
    <artifactId>maven-bundle-plugin</artifactId>
    <extensions>true</extensions>
    <configuration>
        <supportedProjectTypes>
            <supportedProjectType>war</supportedProjectType>
        </supportedProjectTypes>
        <instructions>
            <Export-Package>com.roshka.servlet</Export-Package>
            <Bundle-SymbolicName>${project.artifactId}</Bundle-SymbolicName>
            <Bundle-ClassPath>.,WEB-INF/classes,{maven-dependencies}</Bundle-ClassPath>
            <Embed-Directory>WEB-INF/lib</Embed-Directory>
            <Embed-Dependency>*;scope=compile|runtime;</Embed-Dependency>
            <Embed-Transitive>true</Embed-Transitive>
            <Web-ContextPath>/hello</Web-ContextPath>
            <Webapp-Context>hello</Webapp-Context>
        </instructions>
    </configuration>
</plugin>

但是，当我执行mvn install 时，该包不会创建MANIFEST 文件，以打包到METAINF 文件夹中。

我的 felix 项目有什么问题？创建 OSGI BUNDLE 和 WAR OSGI BUNDLE 的典型 pom.xml 模板是什么？

附言如果我将 WAR TO BUNDLE 更改为 Packaging Maven 描述符，生成的 JAR 工作正常，生成的清单正常。但它不是WEB结构。

Answer 1

可以找到来自 IBM 的答案here，它逐步描述了该过程。可以开发一个脚本来创建一个给定战争的捆绑包，我用 java 编写了一个脚本，作为构建步骤调用。

一个关键的区别是，IBM 步骤将成品保留为 jar，而 jrey 将其保留为 war 文件。这可能是因为 IBM 步骤可能会导致进一步的 CICS 捆绑，据我所知，这需要 jar，至少在使用 RAD 环境时是这样。

Answer 2

我的问题已经用下一个 pom.xml 解决了
