How does Apache Ant resolve duplicate targets - apache

Question

Say I have two targets in ant with the same name in two different build files but, one is imported into the other.
build.xml
<project>
<target name="once">
<echo>once</echo>
</target>
<target name="twice">
<echo>twice-a in build.xml</echo>
</target>
<!-- duplicate target twice imported again from build2.xml -->
<import file="build2.xml"/>
</project>
build2.xml
<project>
<target name="twice">
<echo>twice-a in build2.xml</echo>
</target>
</project>
How does ant resolve duplicate targets ?
If it had been in a single file it would have a duplicate target thrown an error however since its imported its not throwing an error.
When I run ant twice I get
$ ant twice
Buildfile: /Users/nav/Codes/build.xml
twice:
[echo] twice-a in build.xml
BUILD SUCCESSFUL
Total time: 0 seconds
If ant does take the first declaration as the target then why doesn't moving the import statement up in build.xml
<?xml version="1.0"?>
<project>
<!-- import moved to the top -->
<import file="build2.xml"/>
<target name="once">
<echo>once</echo>
</target>
<target name="twice">
<echo>twice-a in build.xml</echo>
</target>
</project>
still outputs the same as
$ ant twice
Buildfile: /Users/nav/Codes/build.xml
twice:
[echo] twice-a in build.xml
BUILD SUCCESSFUL
Total time: 0 seconds

When you assign project names, then you can access the both targets
<project name="build1">
<target name="once">
<echo>once</echo>
</target>
<target name="twice">
<echo>twice-a in build.xml</echo>
</target>
<!-- duplicate target twice imported again from build2.xml -->
<import file="build2.xml"/>
</project>
Build2
<project name="build2">
<target name="twice">
<echo>twice-a in build2.xml</echo>
</target>
</project>
call ant -p
Buildfile: build.xml
Main targets:
Other targets:
build2.twice
once
twice
If not project name is assign the imported target are hidden if they have the same name.
