Eclipse Code Recommenders - Key Features and Functionality
The Eclipse Code Recommenders
The Eclipse Code Recommenders is a powerful plugin for the Eclipse Java Development Tools, integrating AI-driven features to enhance the coding experience. Here are the main features and how they work:
Intelligent Code Completion
Eclipse Code Recommenders provides intelligent code completion by analyzing large amounts of data from various sources, such as open-source repositories like GitHub. This analysis helps in predicting the most likely methods or classes a developer would use in a given context. For example, when using content assist on java.util.Collections, the plugin highlights the most frequently used methods, such as emptyList, along with a percentage indicating how likely such a call is.
Extended Documentation
The plugin offers an Extended Documentation view that shows information about how often certain methods are called or overridden. This feature is particularly useful when learning a new API, as it provides insights into common usage patterns and helps developers make more informed decisions.
Subword Completion
Code Recommenders includes a subword completion feature, which allows developers to find methods or classes even if they only know a part of the name, not necessarily the beginning. This feature significantly improves the efficiency of code completion.
Call Chains and Method Overriding
The plugin helps in identifying call chains, which is useful when dealing with deep method calls, such as getting the Active Window or Status Line Manager. It also lists methods that are frequently overridden when extending a class, making it easier to manage class hierarchies.
Statics-Completion
In version 2.5.0, Code Recommenders introduced statics-completion, which provides recommendations for static methods and fields. For instance, when using java.util.Collections, it suggests the most likely static methods, such as emptyList, along with their usage frequencies. This feature is disabled by default but can be enabled through the preferences.
Community Data and Privacy
The plugin uses a database built from community data, such as open-source repositories, to provide better completions. However, due to privacy concerns, the feature to send community feedback data to the server has been discontinued in later versions, ensuring that user data is not shared without consent.
Model Updates and Maintenance
Code Recommenders checks for updates to its recommendation models and library indexes periodically. It can download these updates automatically, although users can disable this feature if needed. The plugin also interacts with Maven Central to identify libraries used by the developer, but this requires explicit user enablement.
User Feedback and Support
The project engages with users through various channels, including the Eclipse Forum, Bugzilla, and Stackoverflow. This ensures that feedback and support requests are addressed, and the community can contribute to the improvement of the plugin.
Conclusion
In summary, Eclipse Code Recommenders integrates AI-driven insights to improve code completion, documentation, and overall coding efficiency. By leveraging community data and continuous updates, it provides a more intuitive and productive coding environment for Java developers.
Eclipse Code Recommenders - Performance and Accuracy
Eclipse Code Recommenders
Eclipse Code Recommenders is a plugin for the Eclipse IDE that aims to improve the accuracy and usability of code completions and recommendations. Here’s a detailed evaluation of its performance and accuracy, along with some limitations and areas for improvement.
Performance
The performance of Eclipse Code Recommenders has seen significant improvements in recent releases. For instance, the 2.1.0 release has enhanced the performance of loading recommendation models, making the plugin more efficient.
However, there are some potential performance issues to consider:
- The plugin performs network I/O operations to check for updates and download recommendation models, which could impact performance if the network connection is slow. Users can disable auto-download mode to mitigate this.
- There have been reports of performance drops in the Eclipse IDE after certain updates, though these are not specifically attributed to Code Recommenders. Users have noted sluggishness in the IDE after updates, which could be related to various factors including other plugins.
Accuracy
The accuracy of Eclipse Code Recommenders is enhanced through several features:
- Frequency-Based Recommendations: The plugin observes the choices made by developers and prioritizes the most frequently used completions, making it more likely for developers to find their desired choices quickly.
- Subword Completion: This feature allows for method name completions even when the developer only knows a part of the method name, not necessarily the beginning. This improves the usability and accuracy of the autocompletion suggestions.
- Global Implications: While not a direct feature of Code Recommenders, research suggests that considering the global implications of code recommendations can improve their accuracy. This approach, though not integrated into Code Recommenders, highlights the potential for future improvements by considering the entire codebase when making recommendations.
Limitations and Areas for Improvement
- Compatibility Issues: There have been compatibility issues reported, particularly with the Groovy Editor. The content assist in the Groovy Editor can stop working until a restart, which has been a persistent issue that required specific fixes to filter out Code Recommenders categories from the Groovy Editor’s content assist.
- Privacy Concerns: Earlier versions of Code Recommenders had features that sent usage data to the Codetrails server, which raised privacy concerns. Although these features have been deactivated in later versions, it’s an area that needs careful management to ensure user data protection.
- Architectural Issues: The plugin uses Google Guice for dependency injection and Google Guava’s EventBus, which can be inconsistent with Eclipse 4’s architecture. There are plans to potentially move away from these in future releases to align better with Eclipse standards.
In summary, Eclipse Code Recommenders has made significant strides in improving the performance and accuracy of code completions within the Eclipse IDE. However, it still faces some challenges related to compatibility, privacy, and architectural consistency. Addressing these areas can further enhance the plugin’s usability and effectiveness.

Compatibility with Eclipse Versions
Code Recommenders is compatible with Eclipse versions 4.5 (Mars) and later. However, it does not maintain binary backwards compatibility with earlier versions such as Kepler (4.3) and Luna (4.4). For those versions, specific older releases of Code Recommenders (e.g., 2.4.9 and 2.4.10) need to be installed from specific update sites.
Integration with Other Eclipse Projects
Code Recommenders coordinates with other Eclipse projects to ensure seamless functionality. For instance, it works closely with the Eclipse Aether and m2e projects to ensure compatibility with different versions of these libraries. There is also an optional integration with the Eclipse Mylyn project to enhance task-focused UI with intelligent code completion.
Support for Multiple Platforms
Code Recommenders is fully internationalized and supports multiple platforms that are supported by Eclipse. It relies on the Eclipse Babel project for localization, ensuring that the tool can be used in various languages. The tool itself requires JRE 1.7 or newer and runs on all platforms supported by the compatible Eclipse versions.
Network and Data Handling
Code Recommenders performs network I/O for updating recommendation models and checking for new snippets. However, it does not handle personal information or share user code details. Users can disable auto-download of models to prevent any potential data leakage. The tool also supports HTTPS if the remote server does so.
Compatibility Issues with Other Tools
There have been some compatibility issues reported, such as with the Groovy-Eclipse plugin.
