“包 com.ibm.mq 不存在”错误

Question

我正在使用基于 IBM MQ 的 jar 来浏览我的队列以查找特定消息。 在通过 Maven 构建这个项目时，我遇到了这个问题package com.ibm.mq does not exist 。

我也在构建路径和lib文件夹中添加了这个 jar。

由于com.ibm.mq导入，我编写此逻辑的控制器类没有显示任何编译错误。 但是我在通过 Maven 构建时遇到了这个错误！

应该做些什么吗？

请帮忙。

MQ控制器：

如果您有 Maven，为什么要使用 Eclipse Java Build Path？

相反，您应该将此依赖项添加到pom.xml ：

<!-- https://mvnrepository.com/artifact/com.ibm/com.ibm.mq -->
<dependency>
    <groupId>com.ibm</groupId>
    <artifactId>com.ibm.mq</artifactId>
    <version>5.3.07</version>
</dependency>

似乎这个依赖是指一个不存在的 JAR。 我建议您参考以下问题：

• 缺少工件 com.ibm:com.ibm.mqjms:jar: 5.3.07
