I have a active IA, accout but while ant build its showing The evaluation period has expired, can any one help what could be the possibe reason
This is an unexpected behavior.
Try unregistering IA which is used for this ant build and licensing it again.
Navigate to IA_HOME folder in command prompt
Run build.exe -unregister
Register again by running :
build.exe -ls 127.0.0.1:8888 (license serve ip)
build.exe -registerNodeLocked [path_of_license_file]
If issue persist, raise a support ticket.
