In current hadoop-trunk, compile fails when hadoop-maven-plugins-3.0.0-SNAPSHOT.jar doesn't exist in local repository or at maven central repository.
The affected components are:
The error log is as follows
[ERROR] Plugin org.apache.hadoop.maven.plugin:hadoop-maven-plugins:1.0 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.hadoop.maven.plugin:hadoop-maven-plugins:jar:1.0: Could not find artifact org.apache.hadoop.maven.plugin:hadoop-maven-plugins:pom:1.0 in central (http://repo.maven.apache.org/maven2) -> [Help 1]
This can be avoidable if hadoop-maven-plugins is installed before packaging. This is undocumented, so this should get documented.
