安装 org.fusesource.leveldbjni 时抛出 Karaf 异常

Karaf exception is thrown while installing org.fusesource.leveldbjni

您好,我正在尝试在 karaf 中安装以下依赖项

<dependency>
    <groupId>org.fusesource.leveldbjni</groupId>
    <artifactId>leveldbjni-all</artifactId>
    <version>1.8</version>
</dependency>

我遇到以下异常

我正在尝试安装一些 opendaylight 功能,其中一个功能在内部使用了此依赖项。我是不是遗漏了什么,请帮忙。

包 "leveldbjni" 依赖于 "native" 库。原生如 "os dependent"。在 OSGi 中,一个 bundle 可以声明多个本地库,并为每个库指定何时可以加载该库。

在你的错误中,你可以看到这个包可以加载哪个库:

  • windows32/leveldbjni.dll 如果处理器=x86; os名称=Win32
  • windows64/leveldbjni.dll 如果处理器=x86-64; os名称=Win32
  • osx/libleveldbjni.jnilib 如果处理器=x86; os名字=macosx
  • osx/libleveldbjni.jnilib 如果处理器=x86-64; os名字=macosx
  • linux32/libleveldbjni.so 如果处理器=x86; os姓名=Linux
  • linux64/libleveldbjni.so 如果处理器=x86-64; os姓名=Linux

在你的例子中,osname="Windows 8.1",所以没有匹配这个名字的库,需求失败。

每个 OSGi 框架都有一个 "alias" 列表用于映射 osname-s。这取决于您的实施(和版本)。例如,latest version of Equinox 有这样的配置:

Windows8 "Windows 8" "Windows 8.1" "Windows 8.2" "Windows 8.3" Win8 Win32 # Microsoft

Felix 中:

felix.native.osname.alias.windows8=windows 8,win32

我不知道你用的是哪个框架,哪个版本,但是如果你用的是Felix(默认的),你可以尝试在文件中添加,etc/system.properties :

felix.native.osname.alias.windows8=windows 8,windows 8.1,win32

在 Equinox 中,此问题已在 Bug 423970 上得到跟踪。我不知道如何覆盖这些属性。 Karaf 4 有一个应该可以工作的 Equinox 版本。

也许您可以尝试在 etc/system.properties 中覆盖 os 的值(老实说,我不知道它是否有效,因为这个值应该被发现 - 这是一个丑陋的黑客硬编码这个值)

org.osgi.framework.os.name = Win32

作为解决方法,通过向 org.osgi.framework.os.name = Win32 添加 org.osgi.framework.os.name = Win32 来硬编码 etc/system.properties 中的 OS。这是 Jeremie B 的回答的最终建议,确实为我解决了这个问题。
