Use provided/compileOnly instead of implementation

0153f65121 you're right - we only need provided/compileOnly. I've made the updates to Maven as well. 2020-12-21 07:12:28 -05:00

Since most users only need the annotations.

# RecordBuilder - Early Access
# RecordBuilder
## What is RecordBuilder
Java 15 introduced [Records](https://cr.openjdk.java.net/~briangoetz/amber/datum.html) as a preview feature. Since Java 9,
features in Java are being released in stages. While the Java 15 version of records is fantastic, it's currently missing important features
for data classes: a builder and "with"ers. This project is an annotation processor that creates:

- ...cannot have type parameters

stripped and forwarding methods are added.

Depending on your IDE you are likely to need to enable Annotation Processing in your IDE settings.
## Enable Preview
Note: records are a preview feature only. You'll need take a number of steps in order to try RecordBuilder:
- Install and make active Java 15 or later
- Make sure your development tool is using Java 15 or later and is configured to enable preview features (for Maven I've documented how to do this here: [https://stackoverflow.com/a/59363152/2048051](https://stackoverflow.com/a/59363152/2048051))
- Bear in mind that this is not yet meant for production and there are numerous bugs in the tools and JDKs.
Note: I've seen some very odd compilation bugs with the current Java 15 and Maven. If you get internal Javac errors I suggest rebuilding with `mvn clean package` and/or `mvn clean install`.
## Customizing
The names of the generated methods, etc. are determined by [RecordBuilderMetaData](https://github.com/Randgalt/record-builder/blob/master/record-builder-core/src/main/java/io/soabase/recordbuilder/core/RecordBuilderMetaData.java). If you want to use your own meta data instance:
