如何使用bnd/maven-bundle-plugin从jar依赖项将资源文件包含在osgi捆绑包中?

问题描述：

我正在使用maven-bundle-plugin(实际上是bnd).

I'm using maven-bundle-plugin (bnd effectively).

从源代码中包含资源文件很简单.

It's straightforward to include a resource file from sources.

例如，在构建期间，资源文件(src/main/resources/some.xml)被移动到target目录(target/classes/some.xml)下，并且可以使用<Include-Resource>指令将其包含在捆绑软件中:

For example, a resource file (src/main/resources/some.xml) is moved under target directory (target/classes/some.xml) during build time and can be included into the bundle using <Include-Resource> instruction:

<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>

让我们有一个依存关系:

Let us have a dependency:

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

如何在从属jar内部引用资源文件?

How to reference resource file inside dependent jar?

换句话说，怎么做

指定类似这样的内容:

specify something like this:

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

代替此:

instead of this:

target/classes/some.xml

是来自依赖项之一的资源出现在输出束jar中吗?

so that resource from one of the dependency appeared in output bundle jar?

答

您可以使用maven-dependency-plugin解压缩依赖项jar，然后将资源包括在jar中.

You can use the maven-dependency-plugin to un-compress your dependencies jar and then include the resource in your jar.

<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>

Include-Resource指令应该是pom相对的，请参见

The Include-Resource instructions is supposed to be pom relative, see Include-Resource, you can probably replace targetwith ${project.build.directory}.
