The "HowToContribute" page has been changed by SomeOtherAccount: https://wiki.apache.org/hadoop/HowToContribute?action=diff&rev1=95&rev2=96 1. Be online for that first build, on a good network 1. To set the Maven proxy setttings, see http://maven.apache.org/guides/mini/guide-proxies.html 1. Because Maven doesn't pass proxy settings down to the Ant tasks it runs [[https://issues.apache.org/jira/browse/HDFS-2381|HDFS-2381]] some parts of the Hadoop build may fail. The fix for this is to pass down the Ant proxy settings in the build Unix: {{{mvn $ANT_OPTS}}}; windows {{{mvn %ANT_OPTS%}}}. - + 1. Tomcat is always downloaded, even when building offline. Setting {{{-Dtomcat.download.url}}} to a local copy and {{{-Dtomcat.version}}} to the version pointed to by the URL will avoid that download. === Generating a patch === ==== Choosing a target branch ====
