获取Apache httpcomponents的问题HttpClient 4.3.x OSGi包在Apache Karaf 2.3.x上工作

Question

当试图安装httpclient-osgi 4.3.2软件包（org.apache.httpcomponents：httpclient-osgi：bundle：4.3 .2在的Apache Karaf OSGi容器在HC Site指定的），我收到以下错误报告：

karaf@root> install mvn:org.apache.httpcomponents/httpclient-osgi/4.3.2 
Bundle ID: 60 
karaf@root> start 60 
Error executing command: Error starting bundles: 
    Unable to start bundle 60: Unresolved constraint in bundle 
    org.apache.httpcomponents.httpclient [60]: Unable to resolve 60.0: 
    missing requirement [60.0] osgi.wiring.package; 
    (&(osgi.wiring.package=org.apache.http.concurrent)(version>=4.3.0) 
    (!(version>=4.4.0))) 

当检查头，似乎它会尝试加载的依赖被标记为私人包裹和类可以在包JAR中找到：

karaf@root> headers 60 

=>

... 
Private-Package = 
org.apache.commons.codec, 
    org.apache.commons.codec.binary, 
    org.apache.commons.codec.digest, 
    org.apache.commons.codec.language, 
    org.apache.commons.codec.language.bm, 
    org.apache.commons.codec.net, 
    org.apache.http, 
    org.apache.http.annotation, 
    org.apache.http.concurrent, 
    org.apache.http.config, 
    org.apache.http.entity, 
    org.apache.http.impl, 
    org.apache.http.impl.entity, 
    org.apache.http.impl.io, 
    org.apache.http.impl.pool, 
    org.apache.http.io, 
    org.apache.http.message, 
    org.apache.http.osgi.impl, 
    org.apache.http.params, 
    org.apache.http.pool, 
    org.apache.http.protocol, 
    org.apache.http.util 

与此同时，该org.apache.http *也被定义为进口包装包：

... 
Import-Package = 
    javax.crypto, 
    javax.crypto.spec, 
    javax.net, 
    javax.net.ssl, 
    javax.security.auth.x500, 
    org.ietf.jgss, 
    org.osgi.framework;version="[1.5,2)", 
    org.osgi.service.cm;version="[1.3,2)", 
    org.apache.commons.logging;version="[1.1.0,1.2.0)", 
    net.sf.ehcache;resolution:=optional, 
    net.spy.memcached;resolution:=optional, 
    org.apache.http.concurrent;version="[4.3.0,4.4.0)", 
    org.apache.http.message;version="[4.3.0,4.4.0)", 
    org.apache.http.impl.entity;version="[4.3.0,4.4.0)", 
    org.apache.http.entity;version="[4.3.0,4.4.0)", 
    org.apache.http.protocol;version="[4.3.0,4.4.0)", 
    org.apache.http.impl.pool;version="[4.3.0,4.4.0)", 
    org.apache.http;version="[4.3.0,4.4.0)", 
    org.apache.http.params;version="[4.3.0,4.4.0)", 
    org.apache.http.util;version="[4.3.0,4.4.0)", 
    org.apache.http.io;version="[4.3.0,4.4.0)", 
    org.apache.http.impl.io;version="[4.3.0,4.4.0)", 
    org.apache.http.config;version="[4.3.0,4.4.0)", 
    org.apache.http.pool;version="[4.3.0,4.4.0)", 
    org.apache.http.impl;version="[4.3.0,4.4.0)" 

这似乎导致在卡拉夫试图找到出口的包裹，并没有激活捆绑。

这个包清单有什么问题吗？或者我错过了什么？ PS：我尝试了老4.3.x和Karaf 2.3.x版本 - 相同的结果。

您需要HttpCore OSGi包和导出Commons Logging API的包以满足HttpClient OSGi包的必需依赖性。
