解决org.apache.rat:apache-rat-plugin check, Too many unapproved license
解决org.apache.rat:apache-rat-plugin check, Too many unapproved license
在Maven打包时，遇到报错信息：
[ERROR] Failed to execute goal org.apache.rat:apache-rat-plugin:0.8:check (default) on project hbase: Too many unapproved licenses: 513 -> [Help 1]
这个是因为有大量源文件缺少版权的头部信息。两种解决办法：
方法一：在各个源文件的头部添加版权信息

方法二：跳过检查
在maven命令中，添加参数：
-Dlicense.skip=true -Drat.ignoreErrors=true
或者添加参数：
apache-rat:check -Drat.numUnapprovedLicenses=9999
其中rat.numUnapprovedLicenses是需要检查源文件的阈值，可以设置得大一点。
