           Summary: options in compilerarg silently overridden by defaults
                    or ignored.
           Product: Ant
           Version: 1.6.2
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Core tasks
        AssignedTo: dev@ant.apache.org
        ReportedBy: daniel.santos@pobox.com


If compilerarg is used to specify an argument that ant supports within the task
then the argument is overridden by that default and no warning is given of this
behavior.  In this case, the argument was completely ignored.

Here is my javac task:
    <javac
        debug="${java.debug.option}"
        srcdir="${src.dir}"
        destdir="${classes.dir}">
        <classpath>
            <path refid="project.class.path"/>
        </classpath>
        <compilerarg value="-Xlint:-unchecked -target 1.4" compiler="java1.5"/>
    </javac>

Here is the ant -verbose output:

Java version:
java -fullversion
java full version "1.5.0_02-b09"

If I add target="1.4" to the javac task it will compile it correctly.  I read
bug#21011 which has some similiarities.  However, this would be a bug because it
ignores your directives (overrides them perhaps) and doesn't tell you that it is
doing so, making it not function correctly or as advertised.

The solution should be to warn when an argument specified in compilerarg (or
anywhere else for that matter) is ignored, overridden or otherwise not carried
out or carried out in a manner other than specified.

This could certainly also be caused by a few other options like the
compiler="java1.5" not working correctly or some other artifact causing the
compilerarg to be ignored.
