Maven如何从项目依赖中聚合源代码

Question

我使用 maven-bundle-plugin 从非 osgi 依赖创建 osgi 插件，我想将此依赖的源代码包含到 projet 构建中。

这是一个示例，我从 jfreechart 创建了一个 OSGI 包，当我发布它时，我想包含 jfreechart 源代码。

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>org.jfree.chart</groupId>
    <artifactId>com.netappsid.org.jfree.chart</artifactId>
    <version>1.0.13</version>
    <name>JFreeChart OSGI</name>
    <packaging>bundle</packaging>


    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.felix</groupId>
                <artifactId>maven-bundle-plugin</artifactId>
                <extensions>true</extensions>
                <configuration>
                    <instructions>
                        <Export-Package>org.jfree.chart.*;org.jfree.data.*</Export-Package>
                        <Bundle-SymbolicName>${pom.artifactId}</Bundle-SymbolicName>
                        <Embed-Dependency>jfreechart;inline=true</Embed-Dependency>
                    </instructions>
                </configuration>
            </plugin>
        </plugins>
    </build>

    <dependencies>
        <dependency>
            <groupId>jfree</groupId>
            <artifactId>jfreechart</artifactId>

我遇到了同样的问题。这是我最终做的：

1. 使用 maven-dependency-plugin 解压源代码

   <plugin>
     <artifactId>maven-dependency-plugin</artifactId>
     <executions>
       <execution>
         <id>unpack-sources</id>
         <goals>
           <goal>unpack</goal>
         </goals>
         <configuration>
           <outputDirectory>${project.build.directory}/sources</outputDirectory>
           <artifactItems>
             <artifactItem>
               <groupId>commons-httpclient</groupId>
               <artifactId>commons-httpclient</artifactId>
               <version>3.1</version>
               <classifier>sources</classifier>
             </artifactItem>
           </artifactItems>
         </configuration>
       </execution>
     </executions>
   </plugin>
   

2. 附加使用 maven-assembly-plugin 构建的源工件

   <plugin>
     <artifactId>maven-assembly-plugin</artifactId>
     <executions>
       <execution>
         <id>source-assembly</id>
         <phase>package</phase>
         <goals>
           <goal>single</goal>
         </goals>
         <configuration>
           <descriptors>
             <descriptor>src.xml</descriptor>
           </descriptors>
         </configuration>
       </execution>
     </executions>
   </plugin>
   

   带有以下描述符（注意描述符id用作分类器；工件默认附加）：

   <?xml version="1.0"?>
   <assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0 http://maven.apache.org/xsd/assembly-1.1.0.xsd">
     <id>sources</id>
     <includeBaseDirectory>false</includeBaseDirectory>
     <formats>
       <format>jar</format>
     </formats>
     <fileSets>
       <fileSet>
         <directory>${project.build.directory}/sources</directory>
         <outputDirectory>/</outputDirectory>
         <useDefaultExcludes>true</useDefaultExcludes>
       </fileSet>
     </fileSets>
   </assembly>
   

Answer 2

如果我理解正确的话......

我不得不自己打包许多无 osgi 的 JAR，以便在 OSGi 应用程序中使用。使用maven-bundle-plugin 时，如果您在清单（或osgi.bnd 文件）中使用Export-Package，则其类将包含在创建的包中。

例子：

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: ACME PostgreSQL Driver Bundle
Bundle-SymbolicName: com.acme.org.postgresql
Bundle-Version: 9.0.801.jdbc4

# NB: I've imported a little too much for what is required.
Import-Package: org.postgresql*;version="9.0-801.jdbc4", \
    javax*, \
    org.w3c.dom, \
    !org.ietf.jgss, \
    !org.dom.xml.views

Export-Package: org.postgresql*;version="9.0-801.jdbc4"

Private-Package: org.w3c.dom*, org.xml*, javax*

在这里，导出的包将包含在 POM 中我的 Maven 依赖项的 JAR 中。

如果你还想包含依赖JAR，那么你可以使用Embed-Dependency:

Embed-Dependency: org.postgresql*;version="9.0-801.jdbc4"
Embed-Transitive: true

如果这是您要找的东西？
