MAcOS上的Maven构建错误：“UTF-8编码的不可映射字符”

Question

我在Eclipse Kepler上开发MacOs。

export JAVA _TOOL_OPTIONS -Dfile.encoding=UTF-8

mvn -version


Picked up JAVA_TOOL_OPTIONS: -Dfile.encoding=UTF-8
Apache Maven 3.0.4 (r1232337; 2012-01-17 09:44:56+0100)

OS name: "mac os x", version: "10.8.4", arch: "x86_64", family: "mac"

但我是通过Eclipse运行maven的，Eclipse说平台编码宏...当我运行一个

清洁安装

在我的pom.xml中，我将其设置为this以设置UTF-8:

     <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
     <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
     <project.resources.sourceEncoding>UTF-8</project.resources.sourceEncoding>

更新：我将eclipse配置改为使用/usr/share/maven，而不是盗用的版本。我仍然有错误，而这次平台编码被很好地设置为UFT-8:

Answer 1

如果它在平台编码设置为MacRoman时工作，但在设置为UTF-8时失败，则意味着ParticipantExistenceValidator不是UTF-8编码。您需要修复文件，而不是配置。

一种简单的方法是使用native2ascii两次，首先将MacRoman转换为unicode转义，然后使用-reverse将转义转换回UTF-8。
