java-1.8-dredd 1.1.0

Java 1.8+ language plugin for semver-dredd

java-1.8-dredd

Java 1.8+ language plugin for semver-dredd.

Installation

# Install via the core package extra
pip install "semver-dredd[java]"

# Or install the plugin distribution directly
pip install java-1.8-dredd

Or install from local path (development):

pip install ./plugins/java-1.8-dredd

Requirements

• Python 3.10+
• semver-dredd >= 1.0.20260704001
• JDK 1.8+ installed (both javac and java must be in PATH)

Usage

Once installed, the plugin is automatically discovered by semver-dredd:

# List plugins to verify installation
semver-dredd plugin list
semver-dredd plugin info java

# Generate snapshot for a Java source directory
semver-dredd snapshot --plugin java --path ./src/main/java --version 1.0.0

# Or use the managed init/status/bake workflow
semver-dredd init ./src/main/java --plugin java --version 1.0.0
semver-dredd status ./src/main/java --plugin java --details
semver-dredd bake ./src/main/java --plugin java

How it works

This plugin bundles a simple Java parser that uses regex-based extraction to identify:

• Public classes and interfaces
• Public/protected fields with types
• Public/protected methods with signatures
• Public static methods are also exposed as package-level functions

The parser is compiled on-the-fly using javac and runs with the bundled SnakeYAML library.

Note: This is a simple regex-based parser suitable for straightforward Java code. For complex codebases, a proper Java AST parser (like JavaParser) would be recommended.

Scope: include / exclude

include and exclude items are Java package prefixes (not glob syntax), matched recursively against the fully package-qualified class/function names the parser produces:

include: [com.example.api]
exclude: [com.example.api.internal]

• Empty include (or omitted) analyzes the whole parsed public API under --path, exactly as without scope.
• A non-empty include switches to allow-list mode: only classes/functions under the listed package prefixes (and nested sub-packages) are kept.
• exclude is applied after include and supports a trailing * for non-recursive (single package level) exclusion, e.g. com.example.api.internal* excludes only that exact package, not deeper nested packages under it.
• include matching nothing produces an empty snapshot API (logged as a warning) rather than falling back to no-scope behavior.
