Build Commands

Full Build

# Clean and build all modules
mvn clean install

# Build without tests (faster)
mvn -q -DskipTests install

Module-Specific Builds

# Build specific module
cd crypto-scout-client
mvn clean package

# Build with dependency resolution from root
cd crypto-scout-collector
mvn clean package -DskipTests

Testing

# Run all tests
mvn test

# Run tests for specific module
cd crypto-scout-test && mvn test

# Run single test class
mvn test -Dtest=AmqpPublisherTest

# Run single test method
mvn test -Dtest=AmqpPublisherTest#shouldPublishPayloadToStream

# Run with extended timeout (slow environments)
mvn -q -Dpodman.compose.up.timeout.min=5 test

# Custom database URL for tests
mvn -q -Dtest.db.jdbc.url=jdbc:postgresql://localhost:5432/crypto_scout test

Clean Build

# Clean all modules
mvn clean

# Clean and rebuild single module
cd crypto-scout-client && mvn clean package -DskipTests

Troubleshooting

Build Failures

# Clear local repo and rebuild
rm -rf ~/.m2/repository/com/github/akarazhev
mvn clean install

# Debug dependency tree
mvn dependency:tree

# Check for updates
mvn versions:display-dependency-updates

Test Failures

# Run with verbose output
mvn test -X

# Skip tests temporarily
mvn install -DskipTests

# Run specific test with debug
mvn test -Dtest=ClassName -Dmaven.surefire.debug
