Gradle 升级 7.2 > 7.3 中断，“此属性的值是最终的，不能进一步更改”（使用 Micronaut 插件？）

Question

我使用 Micronaut 3.1.3 和 Gradle 7.2 来构建我的项目。

切换到 Gradle 7.3后，内置中断会发出一些上下文无关的错误消息：

$ ./gradlew clean build
Executed by Gradle 7.3
- using Java 11.0.13
- using Kotlin 1.5.31
- using Groovy 3.0.9

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project '[PROJECT]'.
> The value for this property is final and cannot be changed any further.

随着--stacktrace一条很长的痕迹出现。以下摘录让我猜测问题可能出在 Micronaut 插件上：

* Exception is:

由于“配置根项目时出现问题”，我不确定我的哪一部分 build.gradle引发了问题。因此，根据我对 Micronaut 插件的第一次猜测，以下摘录告诉您正在使用的插件列表以及该插件的配置：

plugins {
  id('org.jetbrains.kotlin.jvm') version "${kotlinVersion}"
  id('groovy')
  id('org.jetbrains.kotlin.kapt') version "${kotlinVersion}"
  id('com.github.johnrengelman.shadow') version '7.+'
  id('io.micronaut.application') version '2.+'
  id('org.jetbrains.kotlin.plugin.allopen') version "${kotlinVersion}"
  id('com.google.cloud.tools.jib') version '3.+'
  id('org.openapi.generator') version '5.+'
  id('com.heroku.sdk.heroku-gradle') version '2.+'
}

[...]

micronaut {
  runtime('netty')
  testRuntime('spock2')
  processing {
    incremental(true)
    annotations('[PACKAGE]')
  }
}

也许这提供了足够的信息来解决问题的原因？如果没有，请告诉我。

Answer 1

I hit the same issue with my Java build and asked for help on gradle slack channel. It found to be a change in Gradle 7.3 behavior.

This issue contains an explanation of the cause and how to fix it. It helped me to solve the issue with my build: I had options defined in one of the test tasks and then useJUnitPlatform was applied across all test tasks afterwards using this snippet:

tasks.withType(Test).configureEach {
  useJUnitPlatform()    // <-- this line was breaking the build
}

This broke the build after migrating to Gradle 7.3. Removing options solved the problem for me.

这里有一个问题，要求在 Gradle 7.3 中将此破坏性行为转换为警告，并使其成为 8.0 中的破坏性更改。
