Java Package Compiler

Package MATLAB programs for deployment as Java packages

Since R2025a

Description

The Java Package Compiler packages MATLAB^® programs into Java^® packages that you can integrate into Java applications. The interactive menus and dialog boxes used in the compiler apps build compiler.build commands that are customized to your specification.

Compiler app advantages include:

• You can perform deployment tasks with a single intuitive interface.

• You can organize your files in a MATLAB project.

• Your project state persists between sessions.

• You can load previously stored compiler tasks from a prepopulated menu.

• You can package applications with an installer for distribution.

Open the Java Package Compiler App

• MATLAB toolstrip: On the Apps tab, under Application Deployment, click the app icon.

• MATLAB command prompt: Enter javaPackageCompiler.

Examples

• Create Java Package Using Java Package Compiler App

Version History

Introduced in R2025a

R2025a: Class mapping is no longer supported

Since R2025a, use compiler.build.javaPackage or mcc to map MATLAB functions to Java classes.

R2025a: Change in app entry point

In R2024b and earlier releases, you can generate Java packages using the Library Compiler. Starting in R2025a, use the Java Package Compiler to create Java packages.

R2025a: Change in output folder name

In R2024b and earlier releases, the compiler apps generate output files in the folders for redistribution, for redistribution_files_only, and for testing. Starting in R2025a, the compiler apps generate output files in a folder named after the compiler task.
