问题描述



该软件包使用maven构建，它导入gson 。



我在maven中包含gson as required： 

 <依赖项> 
< groupId> com.google.code.gson< / groupId> 
< artifactId> gson< / artifactId> 
< version> 2.3.1< / version> 
< /依赖关系>

构建进行得很顺利。但是，在部署捆绑软件时，我收到Karaf发出的这个警告： 

  2015-05-27 12：45：07,371 |警告| 49-19-bin / deploy | fileinstall | 11  -  org.apache.felix.fileinstall  -  3.2.8 |启动bundle时出错：file：/Users/user/Documents/tools/MyBundle-1.0.0-SNAPSHOT.jar

未安装捆绑包。



Import-Package MANIFEST.MF 开始于：

  Import-包：com.google.gson; version =[2.3,3）

我试图更改它与：

 导入包：com.google.code.gson; version =[2.3,3）

但它给了我一个类似的错误：

 缺少需求[121.13] osgi.wiring.package; （&（osgi.wiring.package = com.google.code.gson）

Google GSON的 MANIFEST.MF 当我构建包时，maven会下载这个版本）：

现在依赖关系已被嵌入，但Karaf无法启动捆绑包。

如果您有 Import-在你的 MANIFEST.MF 中包：com.google.gson; version =[2.3,3]，这意味着你想要一些包要从已部署的包中导入，而不能从嵌入式jar导入。在这种情况下，您应该首先部署 gson-2.3.1.jar 捆绑包（将此文件复制到deploy文件夹），然后部署捆绑包。



如果要将gson库作为简单的非OSGi jar依赖项嵌入，也可以这样做，但是必须从 Import-包：

 < plugin> 
< groupId> org.apache.felix< / groupId> 
< artifactId> maven-bundle-plugin< / artifactId> 
< extensions> true< / extensions> 
<配置> 
<指令> 
< Bundle-SymbolicName> $ {project.artifactId}< / Bundle-SymbolicName> 
< Import-Package>！com.google.gson，*< / Import-Package> 
< Embed-Dependency> gson< / Embed-Dependency> 
< / instructions> 
< / configuration> 
< / plugin>


I am unable to start a bundle in Karaf (version 3.0.1).

The bundle is built using maven and it imports gson.

I included gson in maven as required:

<dependency>
     <groupId>com.google.code.gson</groupId>
     <artifactId>gson</artifactId>
     <version>2.3.1</version>
</dependency>

The build goes fine. However, when deploying the bundle I receive this Warning from Karaf:

2015-05-27 12:45:07,371 | WARN  | 49-19-bin/deploy | fileinstall                      | 11 - org.apache.felix.fileinstall - 3.2.8 | Error while starting bundle: file:/Users/user/Documents/tools/MyBundle-1.0.0-SNAPSHOT.jar

at org.apache.felix.fileinstall.internal.DirectoryWatcher.run(DirectoryWatcher.java:308)[11:org.apache.felix.fileinstall:3.2.8]

The bundle is not installed.

The Import-Package in the MANIFEST.MF begins with:

Import-Package: com.google.gson;version="[2.3,3)"

I tried to change it with:

Import-Package: com.google.code.gson;version="[2.3,3)"

But it gives me a similar error:

missing requirement [121.13] osgi.wiring.package; (&(osgi.wiring.package=com.google.code.gson)

The MANIFEST.MF of Google GSON (the version maven downloads when I build the bundle) is:

I also tried with

<build>
    <plugins>

            <artifactId>maven-bundle-plugin</artifactId>

            <configuration>
                <instructions>
                    <Bundle-SymbolicName>${project.artifactId}</Bundle-SymbolicName>
                    <Import-Package>*;resolution:=optional</Import-Package>
                    <Embed-Dependency>*</Embed-Dependency>
                    <Embed-Transitive>true</Embed-Transitive>
                </instructions>
            </configuration>
        </plugin>
          <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <configuration>
                <skipTests>${skipTests}</skipTests>
            </configuration>
          </plugin>
    </plugins>
</build>

Now the dependencies are embedded but Karaf cannot start the bundle.

解决方案

I believe you have two options here.

If you have Import-Package: com.google.gson;version="[2.3,3)" in your MANIFEST.MF, this means that you want some package to be imported from a deployed bundle, not from an embedded jar. In this case, you should first deploy gson-2.3.1.jar bundle (copy this file to the deploy folder), and then deploy your bundle.

If you want to embed the gson library as a simple non-OSGi jar dependency, this also can be done, but then you have to exclude its packages from Import-Package:

    <plugin>
        <groupId>org.apache.felix</groupId>
        <artifactId>maven-bundle-plugin</artifactId>
        <extensions>true</extensions>
        <configuration>
            <instructions>
                <Bundle-SymbolicName>${project.artifactId}</Bundle-SymbolicName>
                <Import-Package>!com.google.gson,*</Import-Package>
                <Embed-Dependency>gson</Embed-Dependency>
            </instructions>
        </configuration>
    </plugin>
