Struct JavaCompletionProvider 

pub struct JavaCompletionProvider;

Java-specific completion provider (fallback)

This is a fallback provider for Java code when external LSP (jdtls) is unavailable.

Behavior

Generates Java-specific completions including:

• Java keywords (abstract, class, interface, public, private, static, etc.)
• Java-specific snippets (class declarations, method definitions, etc.)
• Java primitive types (int, long, double, boolean, etc.)
• Available symbols from code context

When Used

• External LSP (jdtls) is not configured
• jdtls is not installed or fails to start
• jdtls times out or becomes unresponsive

Limitations

• No type inference or semantic analysis
• Cannot resolve imports or dependencies
• No project-aware completions
• Cannot determine variable scope or type information
• Limited to hardcoded keywords and patterns

Recommended Configuration

For production-quality Java completions, install and configure jdtls:

# Download and install Eclipse JDT Language Server
# See: https://github.com/eclipse/eclipse.jdt.ls

Then configure it in lsp-servers.yaml:

servers:
  java:
    - language: java
      executable: jdtls
      enabled: true

See https://github.com/moabualruz/ricecoder/wiki/External-LSP-Configuration.md for details.
