plugins

codegen-plugins

A separate Gradle project with ProtoData plugins which generate MessageField, MessageOneof, and MessageDef implementations for Proto messages. Also, some other useful Kotlin extensions are generated, e.g. ValidatingBuilder.messageDef() that returns the instance of MessageDef implementation for the current message builder.

The separate Gradle project is needed because the ProtoData plugins, which generate the code, require the newer version of Gradle, 9.4.x at the moment, and Java 17, comparing to Chords-based projects, which require Gradle version 6.9.x and Java 11.

Requirements

• Java 17
• Gradle 9.4.x
• Kotlin 2.3.20

How to use

The Chords Gradle plugin should be used to apply codegen-plugins to a project.

Resources for the Gradle plugin

The following files are copied to the resources/codegen-workspace folder during the build:

• buildSrc folder.
• Gradle wrapper files.

These resources will be packaged into the resulting jar and then used by the Gradle plugin to create a placeholder module for code generation.

This is necessary for the following reasons:

• The Gradle plugin may not keep another copy of these files.
• There is no need to synchronize dependencies between codegen-plugins project and the Gradle plugin.

Modules

• codegen-plugins — the ProtoData plugins generating the code.
