Decompiles a Java .class file from a given file path

Decompiles a Java class from a package name

Decompiles a Java class from a JAR file

Using mcp_javadc with Maven Repository

When you need to decompile Java classes from dependencies in the M2 repository, follow these steps:

Step 1: Find the JAR file location

First, search for the dependency JAR in the local Maven repository:

find ~/.m2 -name "*dependency-name*jar" | grep -v source | grep -v javadoc

Notes:

• Replace dependency-name with the artifact name

• Filter out source and javadoc JARs using grep

• Look for the correct version based on the project's POM file

Step 2: Use the correct mcp_javadc function

Once you have the JAR path, use this function:

For specific class decompilation:

• jarFilePath: The absolute path to the JAR (from Step 1)

• className: Fully qualified class name to decompile

For contextual exploration: If needed, first try to find all available classes in the JAR: jar tf /path/to/the.jar | grep .class | sort

Example workflow:

1. Read the POM file to identify dependency version

2. Search the M2 repository for the JAR

3. Use mcp_javadc to decompile relevant classes

4. If multiple versions exist, select the one matching the project's version requirement
