如何使用 bnd/maven-bundle-plugin 将资源文件从 jar 依赖项包含到 osgi 包中？

我在用着maven-bundle-plugin (bnd有效地）。

从源中包含资源文件很简单。

例如，资源文件（src/main/resources/some.xml) 移至下面target目录 （target/classes/some.xml）在构建期间，可以使用以下命令将其包含到捆绑包中<Include-Resource>操作说明：

<plugin>
    <groupId>org.apache.felix</groupId>
    <artifactId>maven-bundle-plugin</artifactId>
    <version>3.0.1</version>
    <extensions>true</extensions>
    <configuration>
        <instructions>
            <Include-Resource>
                some.xml=target/classes/some.xml,
            </Include-Resource>
        </instructions>
    </configuration>
</plugin>

让我们有一个依赖：

<dependency>
    <groupId>com.example</groupId>
    <artifactId>library</artifactId>
    <version>1.0.0</version>
</dependency>

如何引用依赖内部的资源文件jar?

换句话说，如何

• 指定这样的内容：

  com.example:library:1.0.0:jar/some.xml
  

• 而不是这个：

  target/classes/some.xml
  

以便来自依赖项之一的资源出现在输出包中jar?

您可以使用maven-dependency-plugin解压缩您的依赖项 jar，然后将资源包含在您的 jar 中。

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>
    <executions>
        <execution>
            <id>unpack-dependencies</id>
            <phase>generate-resources</phase>
            <goals>
                <goal>unpack</goal>
            </goals>
            <configuration>
                <markersDirectory>${project.build.directory}/dependencies/dependency-maven-plugin-markers</markersDirectory>
                <artifactItems>
                    <artifactItem>
                        <groupId>DEPENDENCY_GROUPID</groupId>
                        <artifactId>DEPENDENCY_ARTIFACTID</artifactId>
                        <type>OPTIONAL_DEPENCENCY_TYPE</type>
                        <outputDirectory>${project.build.directory}/dependencies/DEPENDENCY_ARTIFACTID</outputDirectory>
                    </artifactItem>
                </artifactItems>
            </configuration>
        </execution>
    </executions>
</plugin>
...
<plugin>
    <groupId>org.apache.felix</groupId>
    <artifactId>maven-bundle-plugin</artifactId>
    <configuration>
        ...
        <instructions>
            ...
            <Include-Resource>target/dependencies/DEPENDENCY_ARTIFACTID/some.xml</Bundle-Activator>
        </instructions>
    </configuration>
</plugin>

The Include-Resource说明应该是 pom 相关的，请参阅包含资源 http://felix.apache.org/documentation/subprojects/apache-felix-maven-bundle-plugin-bnd.html#include-resource，你也许可以替换targetwith ${project.build.directory}.
