Do a mvn clean install.
This will clean whatever created from the previous build, then build your project and add the jars to your local maven repository (.m2\repository)
做一个mvn clean install。
这将清除先前构建中创建的任何内容，然后构建您的项目并将 jar 添加到您的本地 maven 存储库 (.m2\repository)

I also faced the same problem...................Issue got resolved
Do a maven clean and install of the child project and then try
我也遇到了同样的问题.........问题得到解决
做一个 maven clean 并安装子项目，然后尝试
maven clean and install of parent project.
Maven 清理并安装父项目。

I was facing the same issue, I had a parent project that would fail on the Clean Install of a dependent project.
我遇到了同样的问题，我有一个父项目在依赖项目的全新安装时会失败。
I tried all of the above solutions to no avail, running clean install both in eclipse and from command line.
我尝试了上述所有解决方案都无济于事，在 eclipse 和命令行中运行全新安装。
I was able to solve by navigating to the Child Project and Running the following
我能够通过导航到 Child Project 并运行以下命令来解决
- Cleaning the project
mvn clean - Setting as eclipse project
mvn eclipse:eclipse(this forced download of missing jars) - Follow by clean install of Child project
mvn clean install -U - Finally clean install on parent project
mvn clean install -DskipTests -P(if necessary a profile here) -U
- 清理项目
mvn clean - 设置为 eclipse 项目
mvn eclipse:eclipse（强制下载丢失的 jars） - 接下来是全新安装 Child 项目
mvn clean install -U - 最后在父项目上进行全新安装
mvn clean install -DskipTests -P(if necessary a profile here) -U
This helped when maven was not downloading jar's properly listed in the pom.xml, I was not able to find why clean install with Update Snapshots/etc. did not download the missing jars.
当 maven 没有下载在 pom.xml 中正确列出的 jar 时，这会有所帮助，我无法找到为什么使用更新快照/等进行全新安装。没有下载丢失的罐子。
