JarEditor is a VS Code extension for browsing and editing JAR files directly from Explorer.

It is built for the common workflow of inspecting archive contents, editing text resources, decompiling .class files into Java source, recompiling changes, and writing the result back into the original JAR.

• Browse JAR contents in the JarEditor view
• Open and edit text entries inside a JAR
• Open .class entries as decompiled Java source
• Save modified .class files and recompile them
• Add new files, classes, or directories from Explorer
• Delete files or directories from a JAR
• Build edited output back into the original archive

1. Open a workspace that contains JAR files.
2. Find the JarEditor view in Explorer.
3. Expand a JAR and open any entry you want to inspect or edit.
4. Save changes to a .class entry to trigger recompilation.
5. Use Build Jar to merge edited output back into the source JAR.

If you want to edit .class files, make sure a JDK is available. You can configure jarEditor.javaHome, or choose a JDK from the editor toolbar.

Use the Explorer context menu to add files, classes, directories, or delete existing entries.

Search for JarEditor in the VS Code Extensions view and install it from the Marketplace.

npm install npm run build
