eclipse上传工程jar和pom文件到nexus私有库上出现下面的错误，吴水成老师当时只是讲修改用root运行，没有提到改NEXUS_HOME，下面遇到这个问题的朋友或许该高兴吧

Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy (default-deploy) on project edu-common-parent: Failed to deploy artifacts: Could not transfer artifact wusc.edu.common:edu-common-parent:pom:1.0-20180111.151606-1 from/to snapshots (http://192.168.18.42:8081/nexus/content/repositories/snapshots/): Access denied to http://192.168.18.42:8081/nexus/content/repositories/snapshots/wusc/edu/common/edu-common-parent/1.0-

具体办法：到nexus-2.11.2-03/bin下修改nexus文件NEXUS_HOME="/usr/local/nexus"

（刚开始是NEXUS_HOME=""），成功搞定，开心

[root@chenm-03 bin]# vi nexus

# Set this to the root of the Nexus installation
NEXUS_HOME="/usr/local/nexus"

# If specified, the Wrapper will be run as the specified user.

# IMPORTANT - Make sure that the user has the required privileges to write into the Nexus installation directory.

# NOTE - This will set the user which is used to run the Wrapper as well as
#  the JVM and is not useful in situations where a privileged resource or
#  port needs to be allocated prior to the user being changed.
