Java eclipse的ant构建无法解析log4j

您好，我正在尝试用ant构建eclipse hadoop项目，但得到：

TIA

您的

ivy

插件无法解析url

${reactor.repo}/commons logging/commons logging/1.1.1/commons-logging-1.1.pom

检查变量

reactor.repo

已设置。

也有同样的问题。要构建eclipse hadoop插件，请添加：

reactor.repo=https://repository.cloudera.com/content/repositories/snapshots

进入

一般来说，在build.properties中需要类似的内容：

eclipse.home=/home/cloudera/eclipse
reactor.repo=https://repository.cloudera.com/content/repositories/snapshots
version=2.0.0-cdh4.4.0

它对我有用。我从

中获得了hadoop分布。您是否在pom中为reactor.repo指定了一个值？java.net.malformedurexception:无协议：${reactor.repo}/log4j/log4j/1.2.16/log4j-1.2.16.1谢谢。我对这些东西都不熟悉。你知道我会把它放在哪里，应该是什么吗？如果我查看Eclipse中的pom.xml，就会发现maven插件存在问题。这可能是问题所在吗？

eclipse.home=/home/cloudera/eclipse
reactor.repo=https://repository.cloudera.com/content/repositories/snapshots
version=2.0.0-cdh4.4.0
