当我构建时，我得到以下输出：
[ERROR] The build could not read 1 project -> [Help 1]
[ERROR]
[ERROR] The project com.sw.system4:system4-data:0.0.1-SNAPSHOT (C:\work\eclips
e_workspaces\systemiv\system4-parent\system4-data\pom.xml) has 8 errors

我想你可以试试：
>
将版本的文字值放入子pom中
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>3.2.3.RELEASE</version>
<scope>runtime</scope>
</dependency>
清除通常位于C:\users\user.m2\repository的.m2缓存。我会说我在Maven工作时经常这样做。特别是在提交之前,这样我就可以更有信心地运行配置项。您不必每次都使用nuke文件夹，有时只需要您的项目包和.cache文件夹就足够了。
