**一，问题描述：**

*  注释掉已有的jar包，发现Maven Dependencies并没有自动移除该jar包。

 *  在pom.xml中配置好需要下载的jar包依赖，点击保存后，发现并没有下载jar包。![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDI2NDc0NA_size_16_color_FFFFFF_t_70 1]

**三，jar包下载，中途停止：**

*  找到我们的本地maven仓库目录

命令行输入：mvn help:effective-settings

project--》properties---》Java build  path

*  搜索出该目录下的\*lastUpdated.properties结尾的文件并删除
 *  更新项目时将Force Update of Snapshots/Releases点上勾再更新  
    最后在选择maven项目，右键maven-》update project 就可以了。
