Dear maven user and developers,
Attached is pom.xml of Flume. I have some questions as follow, really appreciate your help or guide, thanks !!
1. Why profile id = hadoop-1.0 is the default profile ?
If not specifying -Pxxxxx for mvn command, I found hadoop-1.0 is the default one to use. why is it the default one ? is it because <name>!hadoop.profile</name> is specified in its activation and hadoop.profile is not specified in properties ? Seems not... I tried with adding <hadoop.profile>2</hadoop.profile> into properties, but hadoop-1.0 is still used. This can be proven by the version of dependencies downloaded into .m2 repository
2. hadoop-test-xxxx is needed for profile id = hadoop-2 ?
when I issued "mvn xxxx -Phadoop-2", the following errors came out:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-remote-resources-plugin:1.1:process (default) on project flume-hdfs-sink: Failed to resolve dependencies for one or more projects in the reactor. Reason: Missing:
[ERROR] 1) org.apache.hadoop:hadoop-test:jar:2.4.0
[ERROR] Try downloading the file manually from the project website.
[ERROR] Then, install it using the command:

[ERROR] Alternatively, if you host your own repository you can deploy the file there:

I just wonder and be confused why org.apache.hadoop:hadoop-test:jar:2.4.0 is requested. Because the following statements only appear in profile id = hadoop-1.0
The pom.xml for flume-hdfs-sink is also attached as pom-1.xml. Thanks !
