Expanding Variables in if statements

[Michael Corr]

hi
I'm trying to check if a source string contains a substring, inside an <if> statement, but it doesn't seem to work when the source string is a variable

I have:
    <property name="dir.base" value="this/is/my/working/directory" />
    <if test="${string::contains('${dir.base}','working')}">
      <echo>This is my directory</echo>
    </if>

This never returns true. It doesn't seem to parse the ${dir.base} variable inside the <if> statement

If I change the test to:
    <if test="${string::contains('${dir.base}','base')}">
      <echo>This is my directory</echo>
    </if>

This does return true. So, it appears to treat the variable as a literal and not a variable.

Am I missing something? I tried removing the single quotes around ${dir.base} and got an error about the $ character. I also tried using double quotes, but got an error as well

Is there a better way to check if a string (or path) contains a specific directory?

thanks
Michael

You don't not embed expressions. Write your if as follows:

 

    <property name="dir.base" value="this/is/my/working/directory" />
    <if test="${string::contains(dir.base,'working')}">
      <echo>This is my directory</echo>
    </if>
