OMG. Very frustrating: 1. VM had to be reset multiple times. 2. When trying to run the two pipelines received the following error: "[ERROR] The goal you specified requires a project to execute but there is no POM in this directory (/home/theia). Please verify you invoked Maven from the correct directory. -> [Help 1]" I fixed the problem by (1) compiling, (2) then setting the variables, (3) compiling againg, and (4) finally running the pipelines: Compile the Project: Run Maven to clean and compile the project to ensure that all classes are properly compiled. sh Copy code mvn clean compile Run the Maven Command with Debug Logging: If the problem persists, run Maven with the -e or -X switch to get more detailed error information. This will help in diagnosing the issue further. sh Copy code mvn -e exec:java \ -Dexec.mainClass=${MAIN_CLASS_NAME} \ -Dexec.cleanupDaemonThreads=false \ -Dexec.args=" \ --project=${PROJECT_ID} \ --region=${REGION} \ --stagingLocation=${PIPELINE_FOLDER}/staging \ --tempLocation=${PIPELINE_FOLDER}/temp \ --runner=${RUNNER} \ --inputPath=${INPUT_PATH} \ --tableName=${TABLE_NAME}" Example Command Sequence Navigate to the Project Directory: sh Copy code cd /home/project/training-data-analyst/quests/dataflow/4_SQL_Batch_Analytics/labs Set Environment Variables: sh Copy code export PROJECT_ID=$(gcloud config get-value project) export REGION='us-west1' export BUCKET=gs://${PROJECT_ID} export PIPELINE_FOLDER=${BUCKET} export MAIN_CLASS_NAME=com.mypackage.pipeline.BatchMinuteTrafficSQLPipeline export RUNNER=DataflowRunner export INPUT_PATH=${PIPELINE_FOLDER}/events.json export TABLE_NAME=${PROJECT_ID}:logs.minute_traffic Compile the Project: sh Copy code mvn clean compile Run the Project: sh Copy code mvn exec:java \ -Dexec.mainClass=${MAIN_CLASS_NAME} \ -Dexec.cleanupDaemonThreads=false \ -Dexec.args=" \ --project=${PROJECT_ID} \ --region=${REGION} \ --stagingLocation=${PIPELINE_FOLDER}/staging \ --tempLocation=${PIPELINE_FOLDER}/temp \ --runner=${RUNNER} \ --inputPath=${INPUT_PATH} \ --tableName=${TABLE_NAME}"
