I have written a small shell-script executing a knime workflow. After the execution of the workflow the script checks exit codes. The knime BatchExecutor returns '0' although the console log reports
"INFO main BatchExecutor ========= Workflow did not execute sucessfully ============"
This problem is persistent on Mac OS X. Works fine under Linux.
If possible, how can this be fixed ?
Script excerpt:
echo " Executing calculation..."; "${PATH_TO_KNIME}" -nosplash \ -nosave \ -reset \ -failonloaderror\ -application org.knime.product.KNIME_BATCH_APPLICATION \ --launcher.suppressErrors \ -workflowDir="${WORKFLOW_DIR}" \ -workflow.variable=input_file_list,"file:${TMP_FILE_LIST}",String \ -workflow.variable=result_file_path,"${TARGET_FILE}",String # Checks exit status of knime workflow RESULT=$?; echo $RESULT; if [ $RESULT -ne 0 ]; then echo ""; red; echo "! Execution of knime workflow failed. Aborting further execution." echo ""; noCo; exit 1; else echo ""; green; echo "✓ Execution of knime workflow succeded. Results were written into:"; echo " ${TARGET_FILE}"; echo ""; noCo; exit 0; fi
