Pom.xml: 连接超时和模型版本缺失错误

Question

我在 pom.xml 文件的 eclipse 上收到以下错误。

Multiple annotations found at this line:
    - connect timed out
    - Failure to transfer org.jibx:jibx-maven-plugin:pom:1.2.4 from http://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be 
     reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.jibx:jibx-maven-plugin:pom:1.2.4 from/to central 
     (http://repo.maven.apache.org/maven2): connect timed out
    - Project build error: 'modelVersion' is missing.

pom.xml如下：

任何帮助都会很棒。提前致谢。

jibx-maven-plugin 版本 1.2.4 似乎有问题。
它依赖于：

org.jibx.config:jibx-parent:pom:3-SNAPSHOT

在 Maven Central 中找不到。我用你的 pom.xml 创建了一个简单的项目，当我尝试从命令行用 maven 构建它时 - 我得到了这个：

[ERROR] Plugin org.jibx:jibx-maven-plugin:1.2.4 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.jibx:jibx-maven-plugin:jar:1.2.4: Could not find artifact org.jibx.config:jibx-parent:pom:3-SNAPSHOT -> [Help 1]

然而，在将我的 pom.xml 升级为使用版本 1.2.6 之后，问题消失了，Eclipse 也不再抱怨*插件。

* 它仍然抱怨 插件执行未包含在生命周期配置中 ，但是 there are solutions to this as well.
