Title: Possible bug with property::exists

You need to enclose the property name in single quotes when using property::exists, like this:   <property name=”SingleBuildFile” value=”${property::exists(‘SingleBuildDirectory’)}” />   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Byrd, Payton Sent: Wednesday, November 10, 2004 2:14 PM To: '[EMAIL PROTECTED] Sourceforge. Net' Subject: [Nant-users] Possible bug with property::exists   OK, simple project: <project>     <property name="SingleBuildFile" value="${property::exists(SingleBuildDirectory)}" />     <echo message="!!!! ${SingleBuildDirectory}  ${SingleBuildFile}" />     <echo message="Using single build file mode." if="${SingleBuildFile}" /> </project> If you call it with:  nant -D:SingleBuildDirectory=\EBusiness\Utilities You get:      [echo] !!!! \EBusiness\Utilities  False If you call it with: nant You get: BUILD FAILED D:\EBusiness\default.build(4,26): Property evaluation failed. _expression_: ${property::exists(SingleBuildDirectory)}                                ^^^^^^^^^^^^^^^^^^^^     Property 'SingleBuildDirectory' has not been set. Total time: 0.2 seconds. Shouldn't the first use case return True for ${SingleBuildDirectory} ?   Payton Byrd Trane eBusiness QED Team Phone: 931-905-5386  Fax: 931-648-5901
