我无法在Karaf(版本3.0.1)中启动一个bundle。
该bundle是使用maven构建的,并且导入了gson。
我按要求在maven中包含了gson:
<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
<version>2.3.1</version>
</dependency>
编译过程顺利完成。然而,在部署捆绑包时,我收到了 Karaf 发出的警告:
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

捆绑包未安装。MANIFEST.MF
中的Import-Package
以以下内容开头:Import-Package: com.google.gson;version="[2.3,3)"
我尝试使用以下方式进行更改:
Import-Package: com.google.code.gson;version="[2.3,3)"
但是它给了我一个类似的错误:
missing requirement [121.13] osgi.wiring.package; (&(osgi.wiring.package=com.google.code.gson)

当我构建捆绑包时,Maven下载的Google GSON的MANIFEST.MF
版本为:
Manifest-Version: 1.0
Export-Package: com.google.gson;version=2.3.1, com.google.gson.annotat
ions;version=2.3.1, com.google.gson.reflect;version=2.3.1, com.google
.gson.stream;version=2.3.1, com.google.gson.internal;version=2.3.1, c
om.google.gson.internal.bind;version=2.3.1
Bundle-ClassPath: .

Bundle-Name: Gson

我也尝试了

</build>
现在依赖项已经嵌入,但是Karaf无法启动该捆绑包。
<groupId>com.google.code.gson</groupId>
和osgi.wiring.package=com.google.gson
之间的包不匹配? - javabrettcom.google.gson
包,但据我所知只有com.google.code.gson
。然而,我不知道所需的包为什么是com.google.gson
。 有任何线索吗? - gc5Import-Package
等内容? - javabrett
