打包不成功!

同学你好，建议同学将plugins替换为如下代码再试试。

<plugins>
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.4</version>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
<archive>
<manifest>
<mainClass>com.imooc.maven.PinyinTestor</mainClass>
</manifest>
</archive>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>

祝：学习愉快~

这是我第二次把字符集改回GBK后运行的情况。  之前紧挨着代码的第一次发言的 输出信息，是在GBK情况下运行的输出信息。

同学你好，从如下信息上看，是打包失败了，如：

问一下同学没有修改字符集之前是否存在打包错误呢？

另外如下....是同学再复制时多出来的，还是项目中有的呢？建议去掉再试试。

如果我的回答解决了你的疑惑，请采纳。祝：学习愉快~

我用的win7系统  我把字符集从GBK 改成UTF-8后 重新打包 就出现maven-first-1.0.0-RELEASE.jar这个文件里。但是输出信息里一堆Error，这是打包成功还是不成功？
