HornetQ

Question

我尝试获取一个 HornetQ 示例运行 Tutorial

我在 eclipse 中将依赖项复制到我的 pom.xml 文件中，但出现一些错误，我不明白。我是 Maven 的新手，已经删除了我的 m2 存储库，我总是使用 alt+f5 ("force update on snapshot/releases").

pom.xml 文件：

错误信息：

我不明白为什么缺少组和工件 ID，因为它们是在 pom.xml 中定义的。以及我不明白为什么模型版本无效。

由于我是初学者，希望能在这里得到解答。

此致

Answer 1

您的错误的根本原因是格式错误 XML 由于

Unrecognised tag: 'modelversion'

根据 XML scheme，元素需要命名为 modelVersion（大写 V）。

此外，元素 groupID 和 artifactID 应分别称为 groupId 和 artifactId（小写 d）。

Answer 2

使用以下依赖项：

<dependency>
<groupId>org.hornetq</groupId>
<artifactId>hornetq-core</artifactId>
<version>2.2.23.Final-redhat-1</version>
</dependency>

<dependency>
<groupId>org.hornetq</groupId>
<artifactId>hornetq-jms-client</artifactId>
<version>2.4.7.Final</version>
</dependency>

<dependency>
<groupId>org.hornetq</groupId>
<artifactId>hornetq-jms</artifactId>
<version>2.2.19.Final</version>
</dependency>

<dependency>
<groupId>org.hornetq</groupId>
<artifactId>hornetq-transports</artifactId>
<version>2.1.0.r9031</version>
</dependency>

<dependency>
<groupId>org.hornetq</groupId>
<artifactId>hornetq-logging</artifactId>
<version>2.2.21.Final</version>
</dependency>
