Question

关注this问题。
我使用Bundle-NativeCode标头来指定应该由插件加载的本机库当库与加载它们的代码（System.loadLibrary）位于同一个插件中时，它可以正常工作。但是，当我尝试将库放在单独的插件片段中时，System.loadLibrary会失败并显示UnsatisfiedLinkError。

主机插件的清单（当主机插件中的库时）：

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: Jni
Bundle-SymbolicName: com.ebar.workmode.jni
Bundle-Version: 1.0.0.qualifier
Bundle-Activator: com.ebar.workmode.jni.Activator
Bundle-Vendor: EBAR
Require-Bundle: org.eclipse.core.runtime,
 org.slf4j.api,
 javax.inject;bundle-version="1.0.0",
 com.ebar.workmode.contracts;bundle-version="1.0.0"
Bundle-RequiredExecutionEnvironment: JavaSE-1.8
Bundle-ActivationPolicy: lazy
Export-Package: com.ebar.workmode.jni
Eclipse-ExtensibleAPI: true
Bundle-NativeCode: native/ipcs.dll ; native/ipcs_tcpip_plugin.dll ; osname=win32

插件片段的清单：

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: workmode JNI win x86
Bundle-SymbolicName: com.ebar.workmode.jni.windows.x32;singleton:=true
Bundle-Version: 1.0.0.qualifier
Bundle-Vendor: EBAR
Fragment-Host: com.ebar.workmode.jni;bundle-version="1.0.0"
Bundle-RequiredExecutionEnvironment: JavaSE-1.8
Bundle-NativeCode: native/ipcs_tcpip_plugin.dll ; native/ipcs.dll ; osname=win32

Activator.start主机插件：

@Override
public void start(BundleContext bundleContext) throws Exception { 
        System.loadLibrary("ipcs");      
        System.loadLibrary("ipcs_tcpip_plugin");            
}

从主机插件中删除Bundle-NativeCode标头时出现的错误：

java.lang.UnsatisfiedLinkError: no ipcs in java.library.path
    at java.lang.ClassLoader.loadLibrary(Unknown Source)
    at java.lang.Runtime.loadLibrary0(Unknown Source)

插件片段已添加到产品
插件片段未在目标平台状态选项卡中显示任何错误
插件片段的本机文件夹包含在二进制构建（build.properties）

为什么它没有工作以及如何使主机插件从插件片段加载本机库？或者，有没有办法让插件片段加载其库？
