Can anyone tell me why the exec task, whether or not spawned, hangs in parallel calls? It works fine if I pass -DthreadCount=1. It appears the higher the threadCount used, the quicker it will hang, since -DthreadCount=2 works for a while, but threadCount=5 hangs immediately. This apparently happens when two exec tasks are called simultaneously. Using a forked java task in similar fashion, hangs the same way. The parallel calls of BuildModule work fine when the macrodef uses the ant task.
I've not seen this. I wonder if its some kind of race condition/deadlock in exec or parallel
Thanks, Mike <parallel threadCount='${threadCount}'><BuildModule name='wnc/Cadx' modroot='CadxHtmlUi/Cadx' assembly='wnc' /> <BuildModule name='wnc/Esi' modroot='wcEsi/Esi' assembly='wnc' /> <BuildModule name='wnc/Explorer' modroot='Windchill/DevModules/Explorer' assembly='wnc' /> </parallel><macrodef name="BuildModule"><attribute name="assembly" default=""/> <attribute name="name" default="@{assembly}"/> <attribute name="modroot"/><sequential> <exec executable="ant" spawn="true" vmlauncher="false"><arg line="-f ${module_script} ${ant.arguments} -Dmodroot=${viewroot}/@{modroot <mailto:-Dmodroot=${viewroot}/@{modroot> } [EMAIL PROTECTED]"/ <mailto:[EMAIL PROTECTED]"/> > </exec>
