These conditions are suitable for use in the <bool> element. Unfortunately, they cannot be used in the <condition> task, although all conditions for the <condition> task can be used with the <bool> and the <bool> can be used anywhere that <condition> can be used.

IfPropertyTrue

Given a property name, tests whether the value for that property equals "true" (or "yes" or "on").

<ispropertytrue property="myprop"/> <ispropertytrue property="${someprop}"/>

IfPropertyFalse

Given a property name, tests whether the value for that property equals "false" (or "no" or "off").

<ispropertyfalse property="myprop"/> <ispropertyfalse property="${someprop}"/>

StartsWith

Given a property name, tests whether the value for that property starts with a specified string.

<startswith string="abcdefg" with="abc"/> <startswith string="${myprop}" with="foo"/>

EndsWith

Given a property name, tests whether the value for that ends with with a specified string.

<endswith string="abcdefg" with="efg"/> <endswith string="${myprop}" with="bar"/>

IsGreaterThan

Tests whether the first argument is greater than the second argument. Will automatically treat the arguments as numbers if both arguments consists of only the characters 0 through 9 and optionally a decimal point. Otherwise, a String comparison is used.

<!-- evaluates to true --> <isgreaterthan arg1="6.02" arg2="4"/> <!-- evaluates to false --> <isgreaterthan arg1="bar" arg2="foo"/>

IsLessThan

Tests whether the first argument is less than the second argument. Will automatically treat the arguments as numbers if both arguments consists of only the characters 0 through 9 and optionally a decimal point. Otherwise, a String comparison is used.

<!-- evaluates to false --> <islessthan arg1="6.02" arg2="4"/> <!-- evaluates to true --> <islessthan arg1="bar" arg2="foo"/>
