Gradle 6.x warning when using BootJar task

[rpalcolea]

Hi folks,

While doing some Gradle 6.x nightly release exploration found the following warning when using spring-boot-gradle-pliugin

java.lang.IllegalArgumentException: Deprecation warnings were found (Set the ignoreDeprecations system property during the test to ignore):
 - Property 'bootInf' is not annotated with an input or output annotation. This behaviour has been deprecated and is scheduled to be removed in Gradle 7.0.

It appears to be related to https://github.com/spring-projects/spring-boot/blob/d86c72bf73f58811b992e117aff2196b6bba6d9b/spring-boot-project/spring-boot-tools/spring-boot-gradle-plugin/src/main/java/org/springframework/boot/gradle/tasks/bundling/BootJar.java#L44

One of the Gradle 6.x changes is that validateTaskProperties will now fail builds for plugins where the tasks are missing input/output annotations for properties.

Thanks, @rpalcolea. It should be @Internal to align with the war task's webInf property.

[rpalcolea]

yeah, that's what I thought 👍

Thanks for the quick response!

Hmm, it's @Internal already (#15488):

spring-boot/spring-boot-project/spring-boot-tools/spring-boot-gradle-plugin/src/main/java/org/springframework/boot/gradle/tasks/bundling/BootJar.java

Lines 163 to 168 in 42e0dc1

	@Internal
	public CopySpec getBootInf() {
	CopySpec child = getProject().copySpec();
	this.bootInf.with(child);
	return child;
	}

That looks like a false positive from Gradle to me. What version of Boot's Gradle plugin did you test with?

tried with 2.0.7 and 2.1.1.

Noticed that right now... wondering if doesn't like the getter for some reason, weird since this is a Java project, so really annotation on property wouldn't solve this.

[rpalcolea]

Well... 2.1.8 works fine. I guess it is fine to disregard this.

I got confused with the @since 2.0.3 but Internal was introduced after 2.1.1 👍
