无法启动蓝图容器 - Hello World

Question

我是 Opendaylight 的新手，我正在按照教程构建一个简单的 Hello World 项目 (this tutorial)，但是当我使用 ./karaf 运行项目并检查模块是否使用 log:display | grep hello 初始化时，我得到这个错误：

2017-08-04 12:43:57,159 | INFO  | Event Dispatcher | YangTextSchemaContextResolver    | 55 - org.opendaylight.yangtools.yang-parser-impl - 1.0.2.Boron-SR2 | Provided module name /META-INF/yang/hello.yang@0000-00-00.yang does not match actual text hello@2015-01-05.yang, corrected

使用diag 命令我得到这个输出：

正如我所说，我按照教程进行操作，因此我的文件与 opendaylight 链接完全相同（这是我创建的存储库 GitHub）。

我认为重要的是要说出我是如何生成的。这是解码：

mvn archetype:generate -DarchetypeGroupId=org.opendaylight.controller -DarchetypeArtifactId=opendaylight-startup-archetype -DarchetypeRepository=https://nexus.opendaylight.org/content/repositories/public/ -DarchetypeCatalog=remote -DarchetypeVersion=1.2.2-Boron-SR2

谢谢大家，

在您提供的日志中：

Element 'blueprint' cannot have character [children], because the type's content type is element-only.

所以我认为您的蓝图文件中存在一些错误（无效的 XML）。

如果它与您提供的链接中的 [here] 完全相同，则第 19 行中有一些额外的字符
