Method Reference Analyzer

This project uses the Java Compiler API to analyze method references in a Maven project. It scans all Java files in the project and identifies both method declarations and method references.

Features

• Analyzes all Java files in a Maven project
• Identifies method declarations
• Identifies method references
• Supports custom source directories (via pom.xml configuration)
• Provides detailed logging of findings

Requirements

• Java 11 or higher
• Maven 3.6 or higher

Building the Project

To build the project, run:

mvn clean package

This will create a runnable JAR file in the target directory.

Usage

Run the analyzer by providing the path to your Maven project:

java -jar target/method-reference-analyzer-1.0-SNAPSHOT-jar-with-dependencies.jar /path/to/your/maven/project

The analyzer will:

1. Read the project's pom.xml to determine the source directory
2. Scan all Java files in the project
3. Log all method declarations and method references found

Output

The analyzer will output:

• The path of each Java file being analyzed
• All method declarations found in each file
• All method references found in each file
• Line numbers where methods and references are found

Example Output

INFO: Analyzing file: /path/to/project/src/main/java/com/example/MyClass.java
INFO: Found method: myMethod in 10
INFO: Found method reference: MyClass::myMethod in 15

Error Handling

The analyzer includes error handling for:

• Invalid project paths
• Missing source directories
• File parsing errors
• Maven configuration issues

All errors are logged with appropriate context information.

Running Without Building

You can run the analyzer directly using Maven without building the JAR file by using the following command:

mvn exec:java -Dexec.mainClass="com.example.ReferenceAnalyzerMain" -Dexec.args="/path/to/your/maven/project"

Replace /path/to/your/maven/project with the path to the Maven project you want to analyze.

This command will:

• Compile the code if necessary
• Run the analyzer directly
• Output results as described below

Running Tests

To run the tests for the project, use the following command:

mvn test

This will execute all the tests defined in the project.
