Question

问题描述

我有一个项目reservationVol,我希望将其包含在一个名为的mvc spring项目中reservationVolMvc.我reservationVol在eclipse上编译和测试.我也使用maven命令:mvn compile和mvn package.所有测试都成功运行.

Answer 1

做一个mvn clean install.
这将清除从先前构建创建的任何内容,然后构建项目并将jar添加到本地maven存储库(.m2\repository)

Answer 2

我面临着同样的问题，我有一个父项目在依赖项目的全新安装中会失败。

我尝试了上述所有解决方案均无效，在 eclipse 和命令行中运行 clean install 。

我能够通过导航到子项目并运行以下命令来解决

1. 清理项目mvn clean
2. 设置为 eclipse 项目mvn eclipse:eclipse（这会强制下载丢失的 jars）
3. 接下来是子项目的全新安装mvn clean install -U
4. 最后在父项目上进行全新安装mvn clean install -DskipTests -P(if necessary a profile here) -U

当 maven 没有下载 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/等进行干净安装。没有下载丢失的罐子。

Answer 3

我也遇到了同样的问题..........问题得到解决请
执行maven清理并安装子项目，然后尝试

maven清理并安装父项目。
