（假设你须要导出schema到数据库，能够手动运行mvn hibernate3:hbm2ddl,这也更符合实际开发的须要）。是的，看上去没有不论什么关系。可是问题就是出在了这里！以下我们回退到问题发生时一步步地进行排查。对于本文列出之外的一些细节问题，能够參考：基于Appfuse 2.1高速构建工程的注意事项 本文原文出处: http://blog.csdn.net/bluishglc/article/details/38640715 严禁不论什么形式的转载，否则将托付CSDN官方维护权益！
首先，查看编译之后的输出文件夹target/classes下的中文properties文件。能够确定这件文件本身就没有转码，是native2ascii插件没有正常工作吗？通过检查。发现问题不在native2ascii-maven-plugin的配置上。使用mvn clean package -X查看maven运行过程中的log信息，发现了以下一段有趣的输出：

这段log的有趣之处在于：resources：resources 被运行了两次。第一次是在native2ascii:native2ascii之前，第二次是在 native2ascii:native2ascii 运行之后运行hbm2ddl时又被又一次调用了一次。为了准确地了解resources：resources和native2ascii:native2ascii的运行顺序，我们从它们各自的文档上找到它们默认绑定的周期说明：
resources:resources -> process-resources
native2ascii:native2ascii -> process-classes
maven的默认生命周期例如以下：
<phases> <phase>validate</phase> <phase>initialize</phase> <phase>generate-sources</phase> <phase>process-sources</phase> <phase>generate-resources</phase> <phase>process-resources</phase> <phase>compile</phase> <phase>process-classes</phase> <phase>generate-test-sources</phase> <phase>process-test-sources</phase> <phase>generate-test-resources</phase> <phase>process-test-resources</phase> <phase>test-compile</phase> <phase>process-test-classes</phase> <phase>test</phase> <phase>prepare-package</phase> <phase>package</phase> <phase>pre-integration-test</phase> <phase>integration-test</phase> <phase>post-integration-test</phase> <phase>verify</phase> <phase>install</phase> <phase>deploy</phase> </phases>
依照正常的逻辑， resources：resources会先于native2ascii:native2ascii将全部指定的resource文件进行filter处理之后放置于target文件夹下，之后native2ascii:native2ascii跟进。对指定的文件进行转码。这是很合理的处理方式，而我们的问题就出如今了对resources：resources第二次不正常的调用，这导致了之前经过转码的文件又被未经转码的文件覆盖了。从日志上看，导致resources：resources第二次运行的原因应该是在进入process-test-resources阶段后运行hbm2ddl触发的。也就是说是hbm2ddl的某个动作主动调用了resources：resources，至于详细的细节。是bug还是与maven3的兼容问题，这里我们不再深究，可是解决方法已经变得很清晰上，就是前文提到的做法。
