Gradle plugin 1.7.0 fails with latest Spring Boot 3.1.2, Gradle Kotlin 8.3 with "Task with name 'bootRun' not found in root project"

[matthewadams]

Steps to reproduce:

• Generate a new Gradle Kotlin Spring Boot project (see settings below) from start.spring.io

• Update gradle to 8.3 in gradle/wrapper/gradle-wrapper.properties:

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-8.3-bin.zip
networkTimeout=10000
validateDistributionUrl=true
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

• Add the springdoc plugin to the project:

...
plugins {
	id("org.springframework.boot") version "3.1.2"
	id("io.spring.dependency-management") version "1.1.2"
	id("org.springdoc.openapi-gradle-plugin") version "1.7.0" // <-- added
	kotlin("jvm") version "1.8.22"
	kotlin("plugin.spring") version "1.8.22"
}
...

• Issue command ./gradlew generateOpenApiDocs, observe failure

$ ./gradlew generateOpenApiDocs

@matthewadams I had the same issue with bootRun not found after upgrading.

In our case our plugins section looked like this:

plugins {
	id 'org.springframework.boot' version '2.7.14'
	id 'org.springdoc.openapi-gradle-plugin' version '1.7.0'
	id 'java'
}

The issue went away when reordering this to

plugins {
	id 'java'
	id 'org.springframework.boot' version '2.7.14'
	id 'org.springdoc.openapi-gradle-plugin' version '1.7.0'
}

So maybe try with kotlin before springboot?

It seems that the openapi plugin now depends on a particular initialization order whereas previously (before 1.7.0) it did not matter. If this behavior change is intentional, it should probably be documented somewhere.

I'm having same issue with version 1.7.0.

• First project (Spring Boot 3.1.2, Gradle 8.1.1) was fixed by adding id("application") as first plugin. @nbam-e 's idea about moving Kotlin before Spring Boot also worked for me.
• Second project (Spring Boot 2.7.14, Gradle 7.6.1) was fixed with same way as first project (by adding id("application")).
• Third project (Spring Boot 2.7.14, Gradle 8.1.1) didn't work at all.

Looks like there is a workaround. But it's not working for combination of Spring Boot 2.7.14 & Gradle 8.1.1.

[matthewadams]

Sure enough, reording like this got rid of the problem:

plugins {
	kotlin("jvm") version "1.8.22"
	kotlin("plugin.spring") version "1.8.22"
	id("org.springframework.boot") version "3.1.2"
	id("org.springdoc.openapi-gradle-plugin") version "1.7.0"
	id("io.spring.dependency-management") version "1.1.2"
}

This either needs to be identified as a bug and fixed, or at least documented.

Thanks! 🙏🏼

Any update here? Gradle 8 is out for some time, same for SpringBoot 3, and looks like it's not easy to work with them using springdoc

I guess the fix (at springdoc-openapi-gradle-plugin side) is

a) Either stop using bootRun task directly (e.g. here

springdoc-openapi-gradle-plugin/src/main/kotlin/org/springdoc/openapi/gradle/plugin/OpenApiGradlePlugin.kt

Lines 31 to 32 in e855f9c

	// The task, used to run the Spring Boot application (`bootRun`)
	val bootRunTask = tasks.named(SPRING_BOOT_RUN_TASK_NAME)

). Is the task really helpful?
b) Wait for both org.springframework.boot and java plugins, and massage bootRun only in case both plugins are added (see https://docs.spring.io/spring-boot/docs/current/gradle-plugin/reference/htmlsingle/#reacting-to-other-plugins.java ). For instance: plugins.withId("org.springframework.boot") { plugins.withId("java") { massageBootRunTask() } }
