使用 maven 和 eclipse 的依赖关系问题
Problems in dependencies using maven with ecplise
我对 Maven 了解不多，只了解基础知识，这给我带来了一些问题。
我正在使用 Ecplise Luna 和 Maven（嵌入式版本 3.2.1 / 1.5.1.50109-1819）来管理我的项目。还安装了 JBoss Tools 插件以将我的项目发送到 OpenShift。到目前为止一切顺利。
但是，我在 OpenShift 中遇到了一些错误，在论坛中进行研究发现问题与 mysql-connector-java 的 5.0.8 版本有关。所以我从我的 maven 项目进入 pom.xml 文件，并将 mysql-connector-java 的版本从 5.0.8 更改为 5.1.38，保存了 pom，理论上我的 maven 应该下载version 新版本 (5.1.38) mysql-connector-java 并删除旧版本 (5.0.8)，对吗？
好吧，如果那是应该发生的事情，那不是正在发生的事情。我找不到任何错误，但在我的 lib 文件夹中只有 mysql-connector-java.
的 5.0.8 版本
奇怪我给clean install编译的时候生成成功了，并且生成了MyApp-0.0.1-SNAPSHOT/WEB-INF/libmysql-connector-java-5.0。 8-bin.jar 文件和 mysql- 连接器 -java-5.1.38.jar.
为什么会这样？据我所知，maven 不应将 5.0.8 版本替换为 5.1.38，因为我在 pom.xml?
中更改了版本
知道发生了什么事吗？

Maven 不会将依赖项导入到 eclipse 项目的 'lib' 文件夹中。相反，它将被下载到本地 Maven 存储库（位于 USER_HOME/.m2/repository）。构建项目时，maven 将复制项目 'lib' 文件夹的所有内容，并另外包括本地存储库中引用的 jar。
我怀疑您将旧版本保存在 'lib' 文件夹中，这就是为什么您最终得到两个版本的原因。
我对 Maven 了解不多，只了解基础知识，这给我带来了一些问题。
我正在使用 Ecplise Luna 和 Maven（嵌入式版本 3.2.1 / 1.5.1.50109-1819）来管理我的项目。还安装了 JBoss Tools 插件以将我的项目发送到 OpenShift。到目前为止一切顺利。

Maven 不会将依赖项导入到 eclipse 项目的 'lib' 文件夹中。相反，它将被下载到本地 Maven 存储库（位于 USER_HOME/.m2/repository）。构建项目时，maven 将复制项目 'lib' 文件夹的所有内容，并另外包括本地存储库中引用的 jar。
我怀疑您将旧版本保存在 'lib' 文件夹中，这就是为什么您最终得到两个版本的原因。
