原因是文件的编码格式UTF-8+BOM造成，使用工具UltraEdit等工具可以修改文件编码格式，但不能多个包下同时修改，我觉得太麻烦了!于是网上寻找更好的办法，终于找到了,在编译插件里添加如下图红框部分即可：

以上虽不报错，但没生成class文件，参阅[url=http://yuyajian.iteye.com/blog/2055360]maven编译[/url]
可使用以下插件试试

			<plugin>

				<artifactId>maven-compiler-plugin</artifactId>
				<version>3.1</version>
				<configuration>
					<encoding>UTF-8</encoding>
					<source>1.7</source>
					<target>1.7</target>
					<compilerId>eclipse</compilerId>
				</configuration>
				<dependencies>
					<dependency>

						<artifactId>plexus-compiler-eclipse</artifactId>
