Apache Ant – Check if a file exists with wildcard

The <available> command can help you to check if a file or folder exists. Unfortunately it doesn’t support wildcard checking. Here is an workaround using the <pathconvert> such that we can check if a file or folder exists with wildcard.

<pathconvert property="filePath" setonempty="false" pathsep=" ">
    <fileset dir="./" includes="a_file_name_with_wildcard*" />
<condition property="fileExists">
  <resourcecount when="greater" count="0">
    <fileset file="${filePath}"/>
  <istrue value="${fileExists}"/>
    <echo message="File exists"/>
    <echo message="File NOT exists"/>


Please note that it only works if there is only one file matched the wildcard file name. This is because the <pathconvert> would returns more than one file path if there are more than one file. So it’s not a perfect solution but should be good enough for you to explore more from this example.

Done =)
