eclipse的ant build無法解決log4j

Question

嗨，我正在嘗試建立一個Eclipse hadoop項目的螞蟻，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

有同樣的麻煩。 要構建eclipse hadoop插件，請添加：

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

進入

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

一般來說，您在build.properties中將需要以下內容：

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

它為我工作。 我從https://ccp.cloudera.com/display/SUPPORT/CDH4+Downloadable+Tarballs獲得了hadoop發行版

Answer 2

您的ivy插件無法解析URL ${reactor.repo}/commons-logging/commons-logging/1.1.1/commons-logging-1.1.1.pom

檢查變量reactor.repo是否已設置。
