Gradle编译失败问题汇总
问题1(Could not resolve org.springframework.boot:spring-boot-gradle-plugin:3.0.0)
A problem occurred configuring root project 'clickIn'.> Could not resolve all files for configuration ':classpath'. > 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 8, packaged as a jar, and its dependencies declared externally, as well as attribute 'org.gradle.plugin.api-version' with value '7.5.1' 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 8 - Other compatible attribute: - Doesn't say anything about org.gradle.plugin.api-version (required '7.5.1') - 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 8) - Doesn't say anything about its elements (required them packaged as a jar) - Doesn't say anything about org.gradle.plugin.api-version (required '7.5.1') - 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 8 - Other compatible attribute: - Doesn't say anything about org.gradle.plugin.api-version (required '7.5.1') - Variant 'mavenOptionalRuntimeElements' capability org.springframework.boot:spring-boot-gradle-plugin-maven-optional:3.0.0 declares a runtime of a library, packaged as a jar, and its dependencies declared externally: - Incompatible because this component declares a component compatible with Java 17 and the consumer needed a component compatible with Java 8 - Other compatible attribute: - Doesn't say anything about org.gradle.plugin.api-version (required '7.5.1') - Variant 'runtimeElements' capability org.springframework.boot:spring-boot-gradle-plugin:3.0.0 declares a runtime of a library, packaged as a jar, and its dependencies declared externally: - Incompatible because this component declares a component compatible with Java 17 and the consumer needed a component compatible with Java 8 - Other compatible attribute: - Doesn't say anything about org.gradle.plugin.api-version (required '7.5.1') - Variant 'sourcesElements' 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 8) - Doesn't say anything about its elements (required them packaged as a jar) - Doesn't say anything about org.gradle.plugin.api-version (required '7.5.1')原因
Gradle的版本是7.5.1，它绑定的JDK版本是8，但是spring-boot-gradle-plugin:3.0.0要求JDK版本是17以上。所以要把Gradle绑定的JDK版本升级一下。
我用的是IDEA自带的Gradle，所以升级方法是在配置里找到Gradle，把JDK改为17。
问题2(Failed to resolve imported Maven)
org.gradle.api.GradleException: Failed to resolve imported Maven boms: Could not find org.springframework.cloud:spring-cloud-dependencies:2022.0.0-RC2.Searched in the following locations: - https://maven.aliyun.com/repository/public/org/springframework/cloud/spring-cloud-dependencies/2022.0.0-RC2/spring-cloud-dependencies-2022.0.0-RC2.pom这是我配置的maven仓库地址
repositories { maven { url 'https://maven.aliyun.com/repository/public/' } mavenLocal() mavenCentral()}原因
https://maven.aliyun.com/repository/public/仓库下找不到spring-cloud-dependencies:2022.0.0-RC2这个bom。去阿里云的maven后台【跳转】参考搜索一下版本所在的仓库，发现是在grails-core仓库下面，所以再添加https://maven.aliyun.com/repository/grails-core仓库配置。
repositories { maven { url 'https://maven.aliyun.com/repository/public/' } // 新增 maven { url 'https://maven.aliyun.com/repository/grails-core' } mavenLocal() mavenCentral()}来源地址：https://blog.csdn.net/u010363836/article/details/128351899
