maven-war-plugin的乱码问题（3字节的UTF-8序列的字节3⽆
效）报错
最近⽤到maven-war-plugin这个插件来进⾏打包，但是打完包启动tomcat会遇到这个报错：

就是报
3 字节的 UTF-8 序列的字节 3 ⽆效
错误应该是XML⽂件编码问题。到报错xml发现⾥⾯有中⽂注释，的确乱码了。
我确认了⼀下我XML⽂件的编码:
<?xml version="1.0" encoding="UTF-8"?>
UTF-8的编码，idea默认编码也是UTF-8，再确认了⼀下我pom中的encoding：
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
也配置了UTF-8，但是没起作⽤啊。
想到可能是maven-war-plugin的问题
google⼀下，查了⼀下源码：
发下了⼀个巨⼤⽆⽐的坑
if ( WebappStructure().registerFile( sourceId, targetFilename ) )
{
final File targetFile = new File( WebappDirectory(), targetFilename );
try
{
// fix for MWAR-36, ensures that the parent dir are created first
// TODO: add encoding support (null mean platform encoding)
}
catch ( MavenFilteringException e )
{
throw new MojoExecutionException( e.getMessage(), e );
}
// Add the file to the protected list
return true;
}
else
{
" - " + targetFilename + " wasn't copied because it has already been packaged (filtered)." );
return false;
}
}
看到没有！！
encoding是null，也就是取操作系统默认的编码 我⽤的win
⽽win环境默认是GBK，所以会乱码了。。。⽽且win不像linux可以随意更改系统默认编码所以⽤这个插件打包，有中⽂就坑了。。。。。
⽬前的解决办法是去掉注释中的中⽂。
如有更好的办法，请交流。⼗分感谢
