Maven 2 通过maven创建jar时出现问题

嗨

我正在尝试使用maven创建可执行jar。jar被创建，当我尝试执行java-jar-myjar时，我得到以下错误

原因：java.lang.ClassNotFoundException:org.apache.hadoop.conf.Configuration 位于java.net.URLClassLoader$1.run（URLClassLoader.java:202）

我提取了jar，发现hadoop类不存在。在日志中我可以看到hadoop JAR没有被复制。问题出在哪里

我的pom.xml如下所示：

org.apache.maven.plugins
maven编译器插件
2.3.1

1.6
1.6



org.apache.maven.plugins
maven汇编插件
2.2-β-4


具有依赖项的jar



com.MyClass

您已将hadoop JAR指定为范围为

的依赖项

这意味着它们将在运行时位于类路径上，如果您希望它们包含在jar中，那么请删除范围标记并接受默认范围compile
