org.springframework.boot:spring-boot-gradle-plugin:3.0.0 忽略 Gradle 工具链

Question

spring-boot-gradle-plugin 似乎忽略了我的 build.gradle 文件中的 Java 工具链声明。 我不确定为什么。

   > Could not resolve org.springframework.boot:spring-boot-gradle-plugin:3.0.0.
     Required by:
         project : > org.springframework.boot:org.springframework.boot.gradle.plugin:3.0.0
      > No matching variant of org.springframework.boot:spring-boot-gradle-plugin:3.0.0 was found. The consumer was configured to find a runtime of a library compatible with Java 11, packaged as a jar, and its dependencies declared externally, as well as attribute 'org.gradle.plugin.api-version' with value '7.6
' but:
          - Variant 'apiElements' capability org.springframework.boot:spring-boot-gradle-plugin:3.0.0 declares a library, packaged as a jar, and its dependencies declared externally:
              - Incompatible because this component declares an API of a component compatible with Java 17 and the consumer needed a runtime of a component compatible with Java 11
              - Other compatible attribute:
                  - Doesn't say anything about org.gradle.plugin.api-version (required '7.6')
          - Variant 'javadocElements' capability org.springframework.boot:spring-boot-gradle-plugin:3.0.0 declares a runtime of a component, and its dependencies declared externally:
              - Incompatible because this component declares documentation and the consumer needed a library
              - Other compatible attributes:
                  - Doesn't say anything about its target Java version (required compatibility with Java 11)
                  - Doesn't say anything about its elements (required them packaged as a jar)
                  - Doesn't say anything about org.gradle.plugin.api-version (required '7.6')
          - Variant 'mavenOptionalApiElements' capability org.springframework.boot:spring-boot-gradle-plugin-maven-optional:3.0.0 declares a library, packaged as a jar, and its dependencies declared externally:
              - Incompatible because this component declares an API of a component compatible with Java 17 and the consumer needed a runtime of a component compatible with Java 11
              - Other compatible attribute:

              - Incompatible because this component declares a component compatible with Java 17 and the consumer needed a component compatible with Java 11
              - Other compatible attribute:
                  - Doesn't say anything about org.gradle.plugin.api-version (required '7.6')

              - Incompatible because this component declares a component compatible with Java 17 and the consumer needed a component compatible with Java 11

如果有人可以就我可能做错的事情提供一些指导，我将不胜感激。 一个小小的免责声明：如果我删除插件并简单地在我的 build.gradle 中定义版本标签，一切都可以正常编译。

Answer 1

我认为，您的系统 java 版本是 11（您可以使用“java --version”命令检查），所以我认为您有 2 个选项。

1. 在您的系统上安装 java 17（并再次检查“java --version”）并运行 gradle build 或
2. 下载 jdk 17 并在运行 gradle build 时将其用作命令行参数。 示例 - 如果假设您在“D:\jdk-17”目录中下载 jdk 17，那么您的命令行将变为 -

gradlew -Dorg.gradle.java.home=D:\jdk-17 干净构建

注意：它可能还需要 gradle 版本 6.7.1 或更高版本。
