HornetQ-pom.xml文件无效

Question

I try to get a HornetQ example running Tutorial

I copied the dependencies into my pom.xml file in eclipse but I get some errors, I do not understand. I'm new to maven and already deleted my m2 repository and I always update with alt + f5 ("force update on snapshot/releases").

The pom.xml file:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Error message:

[ERROR] The build could not read 1 project -> [Help 1]
[ERROR]   
[ERROR]   The project [unknown-group-id]:[unknown-artifact-id]:1.0-SNAPSHOT (C:\Users\Julian\workspace\hornetq\pom.xml) has 3 errors

I don't get why group and artifact id is missing since they are defined in the pom. As wells as I don't understand why modelversion is not valid.

Since I am a beginner I hope to get a answer here.

Best regards

Answer 1

The root cause for your error is a malformed XML due to

Unrecognised tag: 'modelversion'

As per the XML scheme , the element needs to be named modelVersion (capital V).

Also, the elements groupID and artifactID should be called groupId and artifactId respectively (lowercase d).

Answer 2

use bellow dependencies :

<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>
