Maven发布插件：不允许与“ [xX] [mM] [lL]”匹配的处理指令目标

Question

最近，当执行Maven版本插件的release：prepare目标时，我们的Ci职位突然浮出水面。我收到一个奇怪的SAX解析错误：

Caused by: org.xml.sax.SAXParseException; lineNumber: 2; columnNumber: 6; The processing instruction target matching "[xX][mM][lL]" is not allowed.

即使我可以mvn clean install该项目就很好...

确定，其中一个子模块在pom.xml的开头具有换行符。 Maven本身显然并不在乎这一点，但是Maven发行插件无法解析此问题并炸死我。
