我尝试使用maven构建hadoop mapreduce项目，但它总是陷入跟随错误， 我已经为纱线执行预定义安装，即Protobuf安装。

我在hadoop 2.2.0源代码构建期间遇到了同样的问题。在“mvn install -DskipTests”期间，此错误出现在“Hadoop Auth”文件夹中。 从某个地方（我不记得从哪里）我开始知道在这个Hadoop Auth文件夹的pom.xml中有一个缺少的依赖项
依赖是
<dependency>
<groupId>org.mortbay.jetty</groupId>
<artifactId>jetty-util</artifactId>
<scope>test</scope>
</dependency>
我添加了此依赖项并再次尝试“mvn install -DskipTests”。我的错误已解决。 希望这也适用于您的情况
