在 apache karaf 启动时安装预编程功能
Pre-programmed feature installs at apache karaf launch
我正在开发一个使用 apache karaf 的 opendaylight 项目。在程序开始时，我需要 karaf 安装一些功能。目前（这有效）我手动将其输入 shell 并安装功能：
$ bin/karaf
Apache Karaf starting up. Press Enter to open the shell now...

Hit '<ctrl-d>' or type 'system:shutdown' or 'logout' to shutdown OpenDaylight.

opendaylight-user@root>
这一切都有效。但是，我需要的是在开始时自动安装此功能。我知道有一个 shell.init.script 文件，我试图将这一行添加到它的底部：
feature:install odl-restconf odl-mdsal-apidocs odl-openflowplugin-flow-services-rest odl-openflowplugin-app-table-miss-enforcer odl-openflowplugin-nxm-extensions odl-restconf-all odl-openflowplugin-flow-services
但是当我这样做时，出现以下错误：
/opt/opendaylight-0.11.0/etc/shell.init.script: Command not found: feature:install
我也知道将 featuresBoot 元素添加到 org.apache.karaf.features.cfg
featuresBoot = odl-restconf（为了便于测试，我将其缩短为只有一个功能）
我得到这个错误：
org.apache.felix.resolver.reason.ReasonException: Unable to resolve root: missing requirement [root] osgi.identity; osgi.identity=odl-restconf; type=karaf.feature; version="[1.10.0,1.10.0]"; filter:="(&(osgi.identity=odl-restconf)(type=karaf.feature)(version>=1.10.0)(version<=1.10.0))" [caused by: Unable to resolve odl-restconf/1.10.0: missing requirement [odl-restconf/1.10.0] osgi.identity; osgi.identity=odl-restconf-nb-rfc8040; type=karaf.feature; version="[1.10.0,1.10.0]" [caused by: Unable to resolve odl-restconf-nb-rfc8040/1.10.0: missing requirement [odl-restconf-nb-rfc8040/1.10.0] osgi.identity; osgi.identity=odl-restconf-common; type=karaf.feature; version="[1.10.0,1.10.0]" [caused by: Unable to resolve odl-restconf-common/1.10.0: missing requirement [odl-restconf-common/1.10.0] osgi.identity; osgi.identity=odl-mdsal-broker; type=karaf.feature; version="[1.10.0,1.10.0]" [caused by: Unable to resolve odl-mdsal-broker/1.10.0: missing requirement [odl-mdsal-broker/1.10.0] osgi.identity; osgi.identity=org.opendaylight.controller.sal-binding-broker-impl; type=osgi.bundle; version="[1.10.0,1.10.0]"; resolution:=mandatory [caused by: Unable to resolve org.opendaylight.controller.sal-binding-broker-impl/1.10.0: missing requirement [org.opendaylight.controller.sal-binding-broker-impl/1.10.0] osgi.wiring.package; filter:="(&(osgi.wiring.package=org.osgi.service.blueprint)(version>=1.0.0)(!(version>=2.0.0)))"]]]]]
所以，我可以看出 karaf 至少承认 shell.init.script 和 org.apache.karaf.features.cfg，但是我显然使用了错误的语法。我已经用尽了我的谷歌搜索来寻找正确的语法或寻找这样的例子。事实上，当我为这个问题做 google 时，我得到的建议是 "use the shell.init.script" 文件，没有示例或 link 文档来说明如何使用它。
例如，这里有一个类似的问题 ，但答案并不完整。我不知道把建议的命令放在哪里。
无论如何，我希望这里有人能告诉我在 shell.init.script 或 org.apache.karaf.features.cfg 中使用什么具体命令来实现这个目标。 （目标是等效的初始化命令来完成我可以手动成功完成的操作，如顶部所述）
更新：
我也试过这种类型的命令：
echo "feature:install odl-restconf odl-mdsal-apidocs odl-openflowplugin-flow-services-rest odl-openflowplugin-app-table-miss-enforcer odl-openflowplugin-nxm-extensions odl-restconf-all odl-openflowplugin-flow-services" | /opt/opendaylight-0.11.0/bin/karaf
这也没有用。我没有收到任何错误消息，我只知道我的 restconf 不工作。有趣的是，我确实看到所有功能都通过管道传输到 karaf shell 中，并且 shell 确实似乎冻结了（看起来就像它正在处理命令）但是在光标返回给我后没有继续.
感谢@jamo，他的回答让我找到了答案。我只需要将它添加到 etc/org.apache.karaf.features.cfg:
featuresBoot = odl-restconf,odl-mdsal-apidocs,odl-openflowplugin-flow-services-rest,odl-openflowplugin-app-table-miss-enforcer,odl-openflowplugin-nxm-extensions,odl-restconf-all,odl-openflowplugin-flow-services, 25921329-8d07-420b-af13-94948bf1a78d
我相信技巧在于最终的 25921329-8d07-420b-af13-94948bf1a78d 这是默认 cfg 文件中的一些十六进制值，我确保它保留在那里。
我们在上游 ODL 中专门使用 org.apache.karaf.features.cfg 文件
系统测试。你可以在 this log 中看到它，但具体来说，这是
它看起来像我们的一个 yangtools 工作：

你在 featuresBook 的问题中有错别字，但我猜那是
