A plugin that allows for adding a java.lang.annotation.Repeatable annotation even if compiled prior to Java 8 which introduces this annotation. As the annotation is not present on previous JVM versions, it is ignored at runtime for older JVM versions what makes this approach feasible.

Applies this plugin.

Parameters
builder:DynamicType.Builder<?>

The builder to use as a basis for the applied transformation.

typeDescription:TypeDescription

The type being transformed.

classFileLocator:ClassFileLocator

A class file locator that can locate other types in the scope of the project.

Returns:DynamicType.Builder<?>

closeback to summary
public void close()

Implements java.io.Closeable.close.

Doc from java.io.Closeable.close.

Closes this stream and releases any system resources associated with it. If the stream is already closed then invoking this method has no effect.

As noted in AutoCloseable#close(), cases where the close may fail require careful attention. It is strongly advised to relinquish the underlying resources and to internally mark the Closeable as closed, prior to throwing the IOException.
