Ant Build for Eclipse 无法解析 log4j

Question

嗨，我正在尝试构建一个 eclipse hadoop 项目，但得到：

[ivy:resolve]       :: commons-logging#commons-logging;1.1.1: several problems occurred while resolving dependency: commons-logging#commons-logging;1.1.1 {common=[default]}:

Answer 1

有同样的麻烦。要构建 eclipse hadoop插件，请添加：

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

到

hadoop_source_pack/src/hadoop-mapreduce1-project/src/contrib/eclipse-plugin/build.properties

一般来说，在你的build.properties中需要这样的东西：

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 https://ccp.cloudera.com/display/SUPPORT/CDH4+Downloadable+Tarballs 那里得到了哈多普发行版

Answer 2

您的ivy插件无法解析网址${reactor.repo}/commons-logging/commons-logging/1.1.1/commons-logging-1.1.1.pom

检查变量reactor.repo是否设置。
