环境：idea编译器，SSM框架。

## 一.报错： ##

\[ERROR\] Failed to execute goal org.apache.maven.plugins:maven-install-plugin:2.4:install (default-install) on project XXX: Failed to install metadata XXX/maven-metadata.xml: Could not parse metadata 路径\\maven-metadata-local.xml: only whitespace content allowed before start tag and not \\u0 (position: START\_DOCUMENT seen \\u0... @1:1) -> \[Help 1\]

Java项目编译时报错。

## 二.原因： ##

不能编译xx路径下的maven-metadata-local.xml，这个maven-metadata-local.xml的作用是记录了项目元数据，例如groupId，artifactId，version。我们的每次提交都会更新maven-metadata-local.xml，当在maven仓库下载jar包时，也会根据这个文件进行jar包的查找。

没有关项目，又直接运行了，maven-metadata-local.xml被占用无法编译。

## 三.解决： ##

找到路径下的maven-metadata-local.xml，删除掉，然后clean一下项目就可以了。
