evo-maven-build-diagnosis

Diagnoses Java Maven build failures by analyzing error logs and .travis.yml configuration.

Key Functions

• execute_maven_build(project_dir, goals, java_home, timeout_secs, pom_file) - Run Maven build via subprocess
• parse_compilation_errors(maven_log) - Extract compilation errors with file/line/col/message
• parse_dependency_errors(maven_log) - Extract missing dependency artifacts
• parse_plugin_errors(maven_log) - Extract plugin execution failures
• parse_pom_errors(maven_log) - Extract POM-related errors (missing files, invalid XML)
• parse_version_incompatibilities(maven_log) - Extract source/target version issues
• detect_java_version_from_pom(pom_path) - Read Java version from pom.xml
• classify_build_failure(maven_log) - Classify the primary failure type
• analyze_travis_yml(travis_yml_path) - Check .travis.yml for issues like wrong file references
• write_diagnosis_report(report_path, analysis_results, log_analysis, travis_analysis) - Write failed_reasons.txt

Usage

import sys
sys.path.insert(0, '/app/environment/skills/evo-maven-build-diagnosis/scripts')
from utils import (
    execute_maven_build, classify_build_failure, analyze_travis_yml,
    write_diagnosis_report, parse_compilation_errors, parse_pom_errors
)

# Analyze build logs
with open('build.log') as f:
    log = f.read()
analysis = classify_build_failure(log)

# Check .travis.yml
travis = analyze_travis_yml('.travis.yml')

# Write report
write_diagnosis_report('failed_reasons.txt', analysis, log_analysis=analysis, travis_analysis=travis)

Common Error Patterns

1. POM Configuration: Missing/wrong POM file references (e.g., build.pom.xml vs build-pom.xml)
2. Version Incompatibility: Source/target version no longer supported by JDK
3. Dependency Resolution: Missing artifacts, tools.jar not found in JDK 9+
4. Compilation: Cannot find symbol, missing imports, missing method implementations
5. Plugin Execution: Failed plugin goals
