我和一个朋友在vscode上合作,但是我朋友的spring工作得很好,但是我的不行。总共有两个错误。
我尝试了各种措施,如gradle插件和java版本,但它不起作用。作为参考,java版本为17.0.5,适用于mac和vscode。感谢观看。

这条线
找不到org.springframework. Boot :spring-boot-gradle-plugin:3.0.4的匹配变体。消费者被配置为查找与Java 8兼容的库的运行时,打包为jar,其依赖项在外部声明,以及值为“7.6.1”的属性“org.gradle.plugin.api-version”,但是:
声明您的项目需要与Java 8兼容的库。但是,

  • Variant 'runtimeElements' capability org.springframework. Boot :spring-boot-gradle-plugin:3.0.4声明了一个库的运行时,打包为jar,其依赖关系对外声明:- 不兼容,因为此组件声明了与Java 17兼容的组件,而使用者需要与Java 8兼容的组件

说它所能找到的是一个需要Java 17的库,这是正确的,因为Sping Boot 3需要Java 17。
因此,您的本地构建以某种方式运行在Java 8上或以Java 8作为目标配置。您应该通过运行java -version来检查您的shell是否运行Java 17或更高版本。这同样适用于您的IDE配置。
