Troubles with Jabel 0.3.0

Hi! trying to use Jabel 0.3.0 with gradle settings:

sourceCompatibility = JavaVersion.VERSION_11
targetCompatibility = JavaVersion.VERSION_1_8

tasks.withType(JavaCompile).all {
	options.compilerArgs = [
			"--release", "8", // Avoid using Java 9+ APIs
			"--enable-preview",
	]

	doFirst {
		options.compilerArgs = options.compilerArgs.findAll {
			it != "--enable-preview"
		}
	}
}

dependencies {
	annotationProcessor "com.github.bsideup.jabel:jabel-javac-plugin:0.3.0"
}

and i get an error on compileJava (on var usage).

But when i downgrade jabel version to 0.2.0 i see

Jabel: initialized. Enabled features: 
	- DIAMOND_WITH_ANONYMOUS_CLASS_CREATION
	- PRIVATE_SAFE_VARARGS
	- EFFECTIVELY_FINAL_VARIABLES_IN_TRY_WITH_RESOURCES
	- LOCAL_VARIABLE_TYPE_INFERENCE

and it work correct.

What can be wrong with settings for 0.3.0? Please advise.

@bsideup it work. Thank you so much! I think it wiil be useful to add information about testAnnotationProcessor to readme.

@AlexRomanch since tasks.withType(JavaCompile).all is used, you need to also add Jabel to testAnnotationProcessor - unfortunately, Gradle does not inherit it automatically.

And yes, Jabel should work perfectly fine with any Java project, Spring Boot included.
