Question

我尝试在ubuntu桌面12.04中安装Hoop。我已经安装了hadoop-1.0.2。我的安装遵循http://cloudera.github.com/hoop/docs/latest/ServerSetup.html 我安装了maven 3.0.4，git the hoop。但是，当我这样做时，问题就出现了，

hoop $ mvn clean package site assembly:single

问题是：

[FATAL] Non-parseable POM /home/pc/.m2/repository/com/sun/jersey/jersey-project/1.4/jersey-project-1.4.pom: end tag name </body> must match start tag name <hr> from line 5 (position: TEXT seen ...</center>\r\n</body>... @6:8)  @ /home/pc/.m2/repository/com/sun/jersey/jersey-project/1.4/jersey-project-1.4.pom, line 6, column 8

和

[ERROR] /home/pc/hoop/hoop-server/src/main/java/com/cloudera/hoop/Hoop.java:[222,23] error: cannot find symbol
[ERROR] class Hoop

[WARNING] Unable to create Maven project from repository.

我该怎么办？

我将maven更改为maven2，然后我做了

rm -rf ~/.m2/repository/com/sun/jersey
rm -rf ~/.m2/repository/org/glassfish/packager
rm -rf ~/.m2/repository/jersey

我现在该怎么办？

Answer 1

由于代理中的间歇性中断（nginx），您的本地Maven 2存储库被搞砸了。由于该文件不是有效的.pom文件，因此Maven 2无法继续。

你应该做的是首先删除它。

rm -rf ~/.m2/repository/com/sun/jersey
rm -rf ~/.m2/repository/org/glassfish/packager
rm -rf ~/.m2/repository/jersey

之后，再次运行Maven mvn命令。

Answer 2

maven 2.0在环安装中不起作用。关于maven 3.0.4中的问题，您可以尝试使用官方文件更新pom.xml。只需在谷歌搜索jersey-project-1.4.pom。
