ant check is copy file succeeded

I have the following ant script that copies a file to DIR A if the file is different:

<copy todir="<DIR A>" verbose="true" preservelastmodified="true">
   <fileset file="< file A">
      <different targetdir="<DIR A>" ignorefiletimes="true"/>
   </fileset>
</copy>

What I need to accomplish is to "check" if the copy happened in order to do "something else" as well.

Run a test before the copy to see if the files are different. Then run a test after the copy to see if the files are the same.

The <condition> task's <filesmatch> condition detects whether two files have identical content.

Here's some code:

<project name="ant-copy-changed-file-test" default="run">

    <target name="run" depends="-copy,-post-copy"/>

    <target name="-copy">
        <condition property="copy-should-happen">
            <not>
                <filesmatch file1="${file_A}" file2="${dir_A}/file_A"/>
            </not>
        </condition>

        <copy todir="${dir_A}" verbose="true" preservelastmodified="true">
           <fileset file="${file_A}">
              <different targetdir="${dir_A}" ignorefiletimes="true"/>
           </fileset>
        </copy>

        <condition property="copy-happened">
            <and>
                <isset property="copy-should-happen"/>
                <filesmatch file1="${file_A}" file2="${dir_A}/file_A"/>
            </and>
        </condition>
    </target>

    <target name="-post-copy" if="copy-happened">
        <echo>Copy happened!</echo>
    </target>
</project>
