Welcome to Gradle 9.0.0!

Here are the highlights of this release:
 - Configuration Cache is the recommended execution mode
 - Gradle requires JVM 17 or higher to run
 - Build scripts use Kotlin 2.2 and Groovy 4.0
 - Improved Kotlin DSL script compilation avoidance

  • Gradle 版本是 8.7 （从报错里的 org.gradle.plugin.api-version=8.7可以看出）。
  • 插件版本：
  • spotless-plugin-gradle:6.25.0 需要 JDK11+
  • sonarqube-gradle-plugin:5.0.0.4638 需要 JDK11+
  • 你现在项目/环境在用 JDK 8 （报错里多次提到 compatible with Java 8）。

由于我的 JDK 版本是 8，所以最好的选择是降级。

  • 配置 maven-publish 插件

maven-publish 是 Gradle 官方提供的插件，用来生成和发布 Maven 兼容的产物（jar、pom.xml 等）。

最常见用途就是：

  • 在本地生成一个 pom.xml
  • 或者把构建好的库发布到 ~/.m2/repository（本地 Maven 仓库）
javascript 复制代码 
plugins {
    id 'java'
    id 'maven-publish'
}

publishing {
    publications {
        mavenJava(MavenPublication) {
            from components.java
        }
    }
}
  • 生成 POM 文件
vbnet 复制代码 
wechatpay-java % ./gradlew generatePomFileForMavenJavaPublication

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

For more on this, please refer to https://docs.gradle.org/8.7/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.

将 build/publications/mavenJava/pom-default.xml 复制到项目根目录下，重命名为 pom.xml。
