Gradle构建失败并出现HTTPS必需错误

Question

这是我的构建脚本

plugins {
id 'java'
id 'maven-publish'
}

repositories {
   mavenCentral()
}

dependencies {
implementation 'org.springframework.boot:spring-boot-starter-data-solr:2.2.6.RELEASE'
implementation 'org.springframework.boot:spring-boot-starter-web:2.2.6.RELEASE'
implementation 'org.springframework.boot:spring-boot-starter-websocket:2.2.6.RELEASE'
implementation 'com.okta.spring:okta-spring-boot-starter:1.4.0'
implementation 'org.springframework.boot:spring-boot-starter-log4j2:2.2.6.RELEASE'

implementation 'org.janusgraph:janusgraph-cql:0.5.1'
implementation 'io.dropwizard.metrics:metrics-core:3.2.2'
implementation 'org.janusgraph:janusgraph-solr:0.5.1'

testImplementation 'org.assertj:assertj-core:3.16.0'
testImplementation 'org.testcontainers:testcontainers:1.14.1'
}

当我运行“ gradle buld”时，出现错误：

Execution failed for task ':compileJava'.
> Could not resolve all files for configuration ':compileClasspath'.
   > Could not resolve io.dropwizard.metrics:metrics-graphite:3.2.2.

我在做什么错了？
