What I Do

Provide guidance for building, testing, and packaging the crypto-scout multi-module Maven project.

Project Structure

```

```

Build Commands

Full Build

```bash

Clean and build all modules

mvn clean install

Build without tests (faster)

mvn -q -DskipTests install

```

Module-Specific Builds

```bash

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

```bash

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

```bash

Clean all modules

mvn clean

Clean and rebuild single module

cd crypto-scout-client && mvn clean package -DskipTests

```

Build Artifacts

Output Locations

| Module | Artifact | Location |

|--------|----------|----------|

| crypto-scout-test | JAR library | `target/crypto-scout-test-0.0.1.jar` |

| crypto-scout-client | Fat JAR | `target/crypto-scout-client-0.0.1.jar` |

| crypto-scout-collector | Fat JAR | `target/crypto-scout-collector-0.0.1.jar` |

| crypto-scout-analyst | Fat JAR | `target/crypto-scout-analyst-0.0.1.jar` |

Running Fat JARs

```bash

crypto-scout-client

java -jar crypto-scout-client/target/crypto-scout-client-0.0.1.jar

crypto-scout-collector

java -jar crypto-scout-collector/target/crypto-scout-collector-0.0.1.jar

crypto-scout-analyst

java -jar crypto-scout-analyst/target/crypto-scout-analyst-0.0.1.jar

```

Troubleshooting

Build Failures

```bash

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

```bash

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

```
