Felix GoGo Shell 抛出 MalformedURLException:未知协议:Equinox 中的 bundleresource

Felix GoGo Shell throws MalformedURLException: unknown protocol: bundleresource in Equinox

我在写an extension to a Java application called ZAP. The extension is a fat/uber jar that has the Equinox bundle (org.eclipse.osgi) inlined. Additional bundles are also included in this jar, within a sub-directory bundles. The OSGi framework is being launched as outlined in How To Embed OSGi.

我正在尝试让 Felix GoGo shell 工作,遵循 the steps outlined 通过 Eclipse 的 "Console Shell" 文档。它指定了以下必需的包:

除了 Equinox / org.eclipse.osgi。由于 Equinox 不在 class 路径上,我将 org.osgi.framework.system.packages.extra 配置设置为 Equinox 的包指定的 Export-Package 值,可见 here.

框架处于活动状态后,我在 Eclipse 中(或通过 Eclipse 外部的命令行)看到以下堆栈跟踪:

GoGo 似乎没有使用 Equinox URL 处理程序。我注意到以下与它们相关的包不在 Equinox 的 Export-Package:

所以我也将它们包含在 org.osgi.framework.system.packages.extra 包列表中。那没有帮助。

包已安装并启动,没有任何明显错误。

如何让 GoGo 使用 Equinox 的自定义 URL 处理程序?

更新 1:可能是红鲱鱼

在随机故障排除中,我想执行概述的最终着色 jar here。我在同一目录中复制了原始 org.eclipse.osgi 包和阴影 jar。有一个 configuration/config.ini 指定要加载的包。

执行库存包会调出控制台:

$ java -cp ~/.p2/pool/plugins/org.eclipse.osgi_3.11.0.v20160121-2005.jar org.eclipse.core.runtime.adaptor.EclipseStarter -console
osgi> ss
"Framework is launched."


id  State       Bundle
0 ACTIVE      org.eclipse.osgi_3.11.0.v20160121-2005
1 ACTIVE      org.apache.felix.gogo.runtime_0.10.0.v201209301036
2 ACTIVE      org.apache.felix.gogo.command_0.10.0.v201209301215
3 ACTIVE      org.apache.felix.gogo.shell_0.10.0.v201212101605
4 ACTIVE      org.eclipse.equinox.console_1.1.200.v20150929-1405
osgi> exit
Really want to stop Equinox? (y/n; default=y)

正在执行阴影 jar,没那么多:

java -cp semiotics-alpha-1.zap org.eclipse.core.runtime.adaptor.EclipseStarter -console
java.lang.NullPointerException: A null service reference is not allowed.
  at org.eclipse.osgi.internal.framework.BundleContextImpl.getService(BundleContextImpl.java:617)

  at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:231)
  at org.eclipse.core.runtime.adaptor.EclipseStarter.main(EclipseStarter.java:208)

这可能完全是在转移注意力...我对 OSGi 非常无知,这是我第一次 hands-on 使用它。但是,我希望阴影罐的执行方式与库存 Equinox 罐没有什么不同。由于我不明白为什么会有差异,我会在那里挖掘,因为没有更好的挖掘点......

更新 2:类路径上的 Equinox 解决问题

我通过其 lib 目录将 Equinox 包添加到 ZAP 的 class 路径,并将其从内联到扩展 jar 中删除。这样做并调整 ServiceLoader.load 调用以不包含 class 加载程序(默认为系统 class 加载程序)有效:

Starting bundle: org.apache.felix.gogo.shell_0.10.0.v201212101605 [1]
Starting bundle: org.eclipse.equinox.console_1.1.100.v20141023-1406 [2]

osgi> 

根本问题可能是 jar 的内联方式,可能与 MANIFEST.MF 文件有关。可能相关,我现在不需要为 org.osgi.framework.system.packages.extra.

提供值

我将不回答这个问题,因为最初的目的是将 OSGi 库作为阴影工件包含在内。也许 bndtools 可以提供帮助?

好的,似乎缺少描述性 META-INF/MANIFEST.MF 是罪魁祸首:

  • 删除(jar uM...)然后更新(jar um...)阴影罐的 MANIFEST.MF 成为 Equinox 清单的副本,修改 Bundle-Version 数字以 17661700.
  • 从 ZAP 的类路径中删除了 Equinox

然后我按原样加载了扩展程序。 GoGo shell 开始:

osgi> 13177 [AWT-EventQueue-0] INFO org.parosproxy.paros.control.Control  - New Session
ss
"Framework is launched."


id  State       Bundle
0 ACTIVE      org.eclipse.osgi_3.10.102.v20160118-1766
1 ACTIVE      org.apache.felix.gogo.runtime_0.10.0.v201209301036
2 ACTIVE      org.eclipse.emf.common_2.11.1.v20160208-0816
3 ACTIVE      org.apache.felix.gogo.shell_0.10.0.v201212101605

6 ACTIVE      org.eclipse.emf.ecore_2.11.2.v20160208-0816
osgi> 

我看到系统包以相同的修改版本号结尾,因此它对添加的 MANIFEST.MF 表示敬意。所以潜在的问题是一个不完整的系统包清单。复制现有的(Equinox 的)效果很好。它也适用于直接命令行测试:

$ java -cp semiotics-alpha-1.zap org.eclipse.core.runtime.adaptor.EclipseStarter -console
osgi> exit
Really want to stop Equinox? (y/n; default=y)  y

不知道我是否会使用这种方法。至少我知道我需要做什么如果我想使用这种方法
