[Maven中文#872] mvn assembly:assembly打包后文件重复解决办法

[咖啡兔]

用mvn assembly:assembly的时候发现jar包中存在重复的class文件导致不能运行，后来群里面的网友说升级maven-
assembly-plugin插件版本，代码如下：

<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.2-beta-5</version>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
</plugin>

虽然是Beta版本，能解决问题可以了，设置版本号发现控制台打印的日志：
[INFO] org/xml/sax/InputSource.class already added, skipping
[INFO] org/xml/sax/Locator.class already added, skipping
[INFO] org/xml/sax/Parser.class already added, skipping
[INFO] org/xml/sax/SAXException.class already added, skipping
[INFO] org/xml/sax/SAXNotRecognizedException.class already added,
skipping
[INFO] org/xml/sax/SAXNotSupportedException.class already added,
skipping
[INFO] org/xml/sax/SAXParseException.class already added, skipping
[INFO] org/xml/sax/XMLFilter.class already added, skipping
[INFO] org/xml/sax/XMLReader.class already added, skipping

这说明做了文件重复校验

我也遇到过这个问题，由于不影响使用就没有深究，原来是bug呀，谢谢分享。
