Possible disadvantages of JaCoCo

  • Limited Language Support
    JaCoCo is primarily focused on Java and doesn't support other programming languages, which limits its use in polyglot projects.
  • Complex Configuration
    Setting up JaCoCo, especially for large projects or those with complex configurations, can be cumbersome and require a deep understanding of the tool.
  • Performance Overhead
    Running JaCoCo can introduce a performance overhead because of the additional bytecode instrumentation required, which may slow down test execution.
  • Lack of Detailed Documentation
    Users have reported that JaCoCo's documentation can be sparse or outdated, which can make troubleshooting and advanced usage more difficult for new users.
  • Limited Support for Java 8+ Features
    While JaCoCo supports most common Java features, certain newer features introduced in Java 8 and later (like lambda expressions and method references) may not be fully covered or reported incorrectly.
