Issue
Jenkins reports the following error:
[TT] ERROR: No running ECU-TEST instance found, please configure one at first!
Solution
At first, check the installation paths for the configured ecu.test installation in the global tool configuration. Otherwise there could be a limitation when using a 64-bit ecu.test installation running on a machine with 32-bit Java installed only. To solve this architecture incompatibility install a 64-bit Java Runtime Environment and ensure to run your master or agent on this version.
